Description

In 2019, as part of the world-famous annual DJI Airworks conference, representatives of the leading manufacturer of unmanned technologies presented to the participants a new model of a professional quadcopter – DJI Phantom 4 Multispectral (hereinafter referred to as P4M). Although the device was created on the basis of the DJI Phantom 4 RTK model, inheriting the corresponding module from its predecessor, the uniqueness of the new drone was obvious. The drone received a multispectral camera as a regular payload, which turned the platform into an indispensable tool for farmers and agronomists. However, not only for them, since in practice it turned out to be possible to use the device with a multispectral camera for other useful tasks.

What is the purpose of multispectral cameras?

Although the use of multispectral cameras is not limited to agriculture, it is agricultural holdings, farmers and relevant specialists who have been widely using this tool in their work in recent years. Multispectral cameras, unlike the so-called RGB cameras, are able to see objects in the visible and near infrared spectrum. As a result of processing the images obtained in this way, users receive special frames that display the state of plants and soil in a way that the naked human eye cannot see.

Using these images, you can effectively monitor the condition of soils and crops in order to make timely decisions on fertilization, plant treatment, irrigation, and be able to predict future crop volumes. Multispectral imaging is also often used by insurance companies that provide services to farmers and households. In addition to farmers and insurers, multispectral imaging systems are used by biologists, ecologists, foresters, archaeologists, conservationists and many other professionals.

Why do you need the DJI Phantom 4 Multispectral?

According to PwC experts, the market for agricultural drones can grow by several tens of billions of dollars in the coming years. This is due to two key circumstances: the growing demand for food in different countries, as well as the development of digital technologies and the emergence of precision farming. Hence the emergence of more and more new models of specialized drones of various types and a variety of equipment for them, including multispectral cameras.

There are various options for connecting multispectral cameras to UAVs. Some purchase separate modules of such devices to install them on unmanned systems as a payload. Others are trying to save money by redesigning ordinary amateur drones and connecting additional equipment to them or modifying the RGB camera. DJI Phantom 4 Multispectral is a more rational and advanced solution, moreover, a “2 in 1” solution: the platform is equipped with a standard multispectral camera and an RTK module. Here, a special camera has become an integral component of the overall design of the aircraft, while in other models solutions in the form of a removable payload are more common.

The benefits of a solution like the DJI P4M are obvious. In addition to powerful specialized equipment, the user receives a relatively compact, mobile solution that can be conveniently and easily transported to different work sites. The RTK module, on the other hand, can significantly improve the accuracy of measurements and provide the user with much more reliable data than if it were a device equipped only with a camera. Large agricultural holdings are no less interested in this than small farms. The new unmanned platform will also suit other professionals who need to perform multispectral analysis from the air and maintain a high level of measurement accuracy.

Key Applications for the DJI Phantom 4 Multispectral

Let us formulate more clearly for what tasks the DJI Phantom 4 Multispectral can be used and in what areas of activity its operation will be the best solution:

  • Precision agriculture / farming. Here the Phantom 4 Multispectral can be used to improve the accuracy of the farm data depending on the season. The standard multispectral camera will help the user to collect and analyze data that cannot be seen with the naked human eye. The data collected by the Phantom 4 Multispectral, which can then be used by the multispectral P4, can then be used in yield indices such as NDRE or NDVI. In turn, farmers can reduce costs, conserve needed resources, and maximize yields wherever possible.
  • Environmental monitoring and inspection. Regularly checking and maintaining the right amount and quality of vegetation by conventional means is a rather difficult task. But if you use the Phantom 4 Multispectral and the DJI GS Pro app, it will make this routine a lot easier. You will also significantly reduce the time for such inspections. At the same time, the built-in RTK module will provide you with incredible data accuracy (up to 1 cm).

Benefits of the Phantom 4 Multispectral Imaging System

The appearance of P4M on the market is a new step in the development of digital technologies for agriculture. Now aerial photography, including for special tasks, has become much easier, more efficient and faster. In addition, users can combine the operation of the P4M quadcopter with specialized agricultural drones, such as the DJI Agras range, to increase the efficiency and accuracy of farmland processing.

Overview quadrocopter DJI Phantom 4 Multispectral

How is the Phantom 4 Multispectral imaging system arranged and how does it work? It is important to note that the pilot receives information not only from multispectral cameras, but also from RGB cameras, all of which are equipped with a global shutter with a resolution of 2 megapixels. As a result, professionals receive not only high-quality aerial photographs, but also information about the state of the crop. This allows the operator to easily switch between normalized difference vegetation index (NDVI) pre-analysis and RGB video feed to immediately focus on important objects and quickly make decisions about certain mandatory operations (pest control, irrigation and fertilization). At the same time, the shooting is high-quality, detailed and smooth thanks to the built-in camera gimbal with proprietary DJI 3-axis stabilization technology.

Another component that improves the shooting accuracy of the P4M is the sunlight sensor. It is built into the body of the drone in the top panel and serves to measure the intensity of sunlight so that the user can get the most accurate data at any time of the day. This is especially important for obtaining adequate information on the NDVI parameter.

The highest level of accuracy

Data accuracy is an important factor in many aerial photography applications. Agriculture is no exception. With the help of P4M, you will be able to get positioning parameters that are incredible in terms of accuracy, and right during the flight in real time. High accuracy is guaranteed by the RTK module and the TimeSync system developed by DJI.

The TimeSync (Time Synchronization) system is used to synchronize the time of data acquisition during the flight and shooting from the air. The system takes into account the maneuvering time and flight speed of the drone, the time of data acquisition and correlates this with the timers of external sensors and the reference time.

That is, in real conditions, the system constantly synchronizes the operation of the flight controller and 6 P4M cameras. As a result, this solution ensures the accuracy of location parameters up to 1 centimeter. An important contribution to the measurement accuracy is also made by the calibration process, during which the radial and tangential distortion is measured. The received distortion data is taken into account in each case, as it is stored in the metadata of each frame.

However, you can further improve your positioning accuracy by using not only the built-in RTK module, but also a D-RTK 2 mobile station and NTRIP (RTCM Network Transport over Internet Protocol, i.e. a protocol for streaming differential GPS data over the Internet). To do this, you will need a 4G connection (via an appropriate modem) or a wireless connection via WiFi. In order not to buy each module separately, you can use the package offer and purchase the DJI Phantom 4 Multispectral + D-RTK 2 High Precision GNSS Mobile Station.

In particular, they will help you import snapshots and create regular and index maps, as well as view and analyze information. You can plan missions and analyze the received data in GS Pro and Terra. In the latter application, you can also create 2D/3D models of areas of interest to you, including taking into account isolated trees or potential obstacles for the drone. You can read more about the DJI Terra app in the article “DJI Terra App for Mapping and Geodetic Surveys”, and see the features and pricing on the respective pages of DJI GS Pro and DJI Terra. Note that when you purchase a DJI Phantom 4 Multispectral quadcopter, you will already receive the DJI GS Pro app installed on the remote control.

It is also important to note that support for the DJI SDK service allows you to use specialized software from other manufacturers with the P4M.

Phantom 4 RTK

INCREDIBLY SMART. AMAZINGLY ACCURATE. HIGH PERFORMANCE

Phantom 4 RTK. Incredibly smart. Amazingly accurate. high performance

Phantom 4 RTK. The last word in cartography and geodesy

The last word in cartography and geodesy

True professionals in the field of cartography and geodesy will appreciate this compact, incredibly smart and highly accurate drone. We are talking about a new product from DJI – Phantom 4 RTK. Its new module that provides you with the best data, as well as a high-performance image processing system, along with other features, make it an ideal choice for surveying and mapping work.

Phantom 4 RTK. Mapping with incredible accuracy

Mapping with incredible accuracy

Although DJI has previously released aircraft that have been equipped to produce maps with a high degree of accuracy, the introduction of the Phantom 4 RTK was the next step in the development of such technologies and quality standards in the field of surveying. The equipment of the drone helps the user to obtain information in which the accuracy of the parameters is verified to the centimeter. At the same time, the drone flight route is built according to the most optimal scheme.

Horizontal Accuracy

The use of the RTK method allows to achieve the highest degree of horizontal positioning: 1 cm + 1 md.

Vertical Accuracy

The use of the RTK method also allows achieving high vertical positioning accuracy: 1.5 cm + 1 md

Professional photo and video

Photogrammetric Model Accuracy

Aerial survey using the RTK method gives the absolute accuracy of the photogrammetric model horizontally: 5 cm.

Phantom 4 RTK. High precision and safety

High precision and safety

Unlike DJI industrial platforms, the Phantom 4 series models have never been equipped with RTK modules before. The new modification of the famous fourth series, on the contrary, received such equipment for the first time, which gave it new properties. Such a model is sure to attract the attention of professionals, because in addition to a powerful camera and extensive post-processing capabilities, it guarantees the receipt of accurate data on the location of the drone in real time, moreover, with unprecedented accuracy (1 cm) and a minimum error in image metadata.

However, the benefits of the Phantom 4 RTK don’t stop there. The presence of an RTK module is important, but it is equally important to ensure safe piloting, especially in conditions of strong interference and weak signal, which are usually characteristic of urban environments. Therefore, in addition to the RTK receiver, the Phantom 4 RTK is equipped with a satellite positioning system module. The use of two modules at once – RTK and a satellite systems module – gives a synergistic effect, enhancing the safety of piloting and the degree of accuracy of information for performing geodesy, cartography and inspection tasks.

Phantom 4 RTK. Efficient and convenient integration

Efficient and convenient integration

Flexibility and the ability to integrate a range of developments into workflows is a hallmark and advantage of many DJI products. The Phantom 4 RTK is no exception, as its capabilities can be easily integrated into almost any workflow. It is enough to connect the positioning system to the D-RTK 2 mobile station. To do this, you can use a 4G modem or a WiFi wireless connection and the NTRIP protocol (implies RTCM network transmission via the World Wide Web). The user also gets the option to save the satellite data with the system for future processing.

Phantom 4 RTK. TimeSync system

TimeSync system

The TimeSync system used on the Phantom 4 RTK integrates several important components at once: the flight controller, camera, and RTK module. This greatly improves the efficiency of the geo-positioning module on the drone. However, TimeSync’s tasks are not limited to this, as it is also responsible for using the most accurate metadata of each frame and moving positioning data to the CMOS center. This feature helps to optimize the results of photogrammetric technology, and also helps to obtain location information with the highest accuracy – up to 1 cm.

Phantom 4 RTK. Image Processing Accuracy

Image Processing Accuracy

It is not enough to know exact location data. The high quality of cartography or object data is highly dependent on the capabilities of the imaging system. The Phantom 4 RTK camera system inherits the best of its predecessors: a 1.0-inch 20MP CMOS sensor for high-quality footage, a mechanical shutter to prevent blurry shots when shooting on the move, and other advantages.

Therefore, whatever tasks you solve – creating maps or simply collecting the data you need – everything will be done perfectly. The high resolution will help you achieve a ground resolution of 2.74 cm at a flight altitude of 100 m. And because you need maximum accuracy, a calibration process will be performed for each lens of the system, including measurement of radial and tangential distortion. The resulting distortion data will be stored in the frame metadata so that during post-processing, each shot can be approached individually.

GS RTK App

DJI always strives to make the operation of its drones, and even more so for professional purposes, as convenient and safe as possible. In this case, a special GS RTK application has been developed for such tasks, which will not only help you control the Phantom 4 RTK, but also make it much easier to perform special tasks. For example, you can use the Photogrammetry and Waypoint Flight modes to improve your work efficiency. The application in this way will automate the compilation of the route and the flight along it, and will also simplify the regulation of the degree of overlapping frames, speed and other parameters. These and a number of other features will allow you to carry out the mapping or inspection procedure much faster without compromising quality. The functionality of the application allows you not only to plan a flight and control the operation of the camera,

OcuSync system

This system has been working on the latest DJI models for several years now and has earned only positive feedback from pilots. The reasons become clear if you look at the OcuSync functionality, which allows you to ensure safe piloting and transmission of video images at a distance of up to 7 km. The system can be especially useful if you have to work on a large area. However, it should be borne in mind that the parameters of the system largely depend on the specific piloting conditions and weather conditions. Still, it is recommended – and it is even spelled out in the regulations of a number of countries – to keep the drone in sight, unless otherwise permitted by law.

Compatible with D-RTK 2

For future users of the DJI Phantom 4 RTK, it will be useful to know that the new model is compatible with the D-RTK 2 mobile station, which helps to transmit a differential signal to the aircraft in real time. For cartography, this is of great importance, since in this case accurate data is obtained. An even more important factor can be considered the joint operation of the mobile station and the OcuSync 2.0 transmission system, as a result of which the aircraft receives and transmits information in which the positioning accuracy reaches 1 cm, and in almost all circumstances.

Phantom 4 RTK. Mobile SDK

Mobile Service SDK

DJI is always open for cooperation, especially when it comes to creating professional applications. When you purchase the Phantom 4 RTK, you get a huge amount of power thanks to its compatibility with DJI’s Mobile SDK. It will allow you to quickly and easily automate and optimize the operation of the drone itself and its components using a mobile gadget.

Phantom 4 RTK. Image Processing Accuracy

Everything is ready for work!

DJI creates products that are ready to go almost immediately. With the GS RTK app, you get an easy way to collect data. Not only the RTK network is at your service, but also the capabilities of the D-RTK 2 mobile station. Thus, all the tools for performing surveying, mapping and inspection tasks are at your disposal.

FAQ

1. What is the difference between the Phantom 4 RTK and previous models in the Phantom series?

The main difference lies in the range of tasks that the old models of the Phantom series are designed to solve. These drones have been developed mainly for use by professional photographers and casual drone enthusiasts. The new Phantom 4 RTK, on ​​the other hand, was built for industrial applications such as high-precision mapping and data collection for a variety of purposes. There are also differences in equipment. If the camera capabilities and even the dimensions of the aircraft of the latest models of the Phantom series are similar, then the previous models do not have an RTK module, but the new Phantom 4 RTK model is equipped with such a device. In addition, it has a completely new TimeSync system for the famous DJI series, as well as a dedicated mapping application and other related components.

2. What propellers does the Phantom 4 RTK have?

The new Phantom 4 RTK features the same propellers as the previous Phantom 4 Pro, the 9450s quick release propellers.

3. Can the Phantom 4 RTK be operated in other countries and regions?

The Phantom 4 RTK has been developed in several versions, which are accordingly suitable for operation in various countries and/or regions. Users need to check the version code on the product packaging or use the GS RTK app to do this (go to the “Aircraft Information” menu and go to the “Firmware / Firmware” section).

Camera

1. What are the main differences between the camera of the new Phantom 4 RTK model and those on the Phantom 4 Advanced/Pro models?

The Phantom 4 RTK and the previous Phantom 4 Pro/Advanced share a number of camera features: they are equipped with a 1-inch 20-megapixel CMOS sensor. However, due to the Phantom 4 RTK’s specialization in mapping and geodetic work, its camera has received improved performance. It is equipped with a new lens distortion recording function. This means that every Phantom 4 RTK camera goes through a calibration process to measure lens distortion, resulting in the corresponding OPEN-CV parameters being recorded. Thus, users can get both original frames without distortion correction, and OPEN-CV distortion parameters in XMP format file. In the latter case, it will come in handy to perform the post-processing process.

2. Will the Phantom 4 Pro ND filters work with the Phantom 4 RTK camera?

Yes. The design and dimensions of these filters are fully compatible with the Phantom 4 RTK camera.

3. Does the Phantom 4 RTK digital signal processor support distortion correction?

No. You won’t be able to correct the distortion in-camera, and the shots will be less accurate than those that have been de-distorted with post-processing software.

Remote control

1. What are the main differences between the new Phantom 4 RTK remote control and the Phantom 4 Pro remote control?

The Phantom 4 RTK remote control has received a number of new features and interface elements that make it more versatile and more suitable for industrial applications. Among these changes, the appearance of a slot for Micro-SD cards, the presence of a built-in speaker, as well as hot-swappable batteries. In addition, the remote control has the function of connecting via the Internet to the RTK (Network RTK) network using a 4G router. And so that the user can start collecting data quickly, each remote comes preloaded with the new GS RTK app.

2. Is it technically possible to use the remote control of any Phantom 4 Advanced/Pro to control the Phantom 4 RTK drone?

No, there is no such possibility. You cannot control the Phantom 4 RTK with the Phantom 4 Advanced or Pro remote control.

3. How can I switch between US (FCC) and European (CE) modes?

The function to switch between FCC and CE modes is not available.

4. How to properly connect the remote control to the Phantom 4 RTK?

For this operation, you need to use the GS RTK app. To learn more about this, please refer to the User’s Guide.

Broadcast video

1. How far can the Phantom 4 RTK broadcast video?

The effective distance for video transmission depends on the method of performing this task, for example, on the position of the antenna, as well as on the external conditions of piloting. When flying in an open area free of obstacles, the maximum effective distance is 7 km (in FCC mode) and 4 km (in CE mode) at 2.4 GHz.

2. What should I do if the application gives the following message: “the signal of the remote control is weak, it is necessary to adjust the antenna”?

This message indicates an incorrect position of the antenna, which, most likely, affected the video broadcast signal, and, as a result, the quality of the live video. You should try to adjust the antennas so that their flat sides are facing the Phantom 4 RTK.

3. Is it possible to continue the automatic mapping mission if the Phantom 4 RTK loses the video broadcast signal during it?

Yes, this is quite possible, because if the signal is lost, you can reconnect and continue performing tasks.

Battery

1. Can Phantom 4 Pro batteries be installed on the new Phantom 4 RTK drone and vice versa?

Since the power supplies from the two models – Phantom 4 RTK and Pro – are cross-compatible and have the same capacity, this can be done. This will not affect the flight parameters in any way.

2. How long does it take to fully charge the Phantom 4 RTK power supply?

When the Phantom 4 RTK battery is fully charged, the procedure will take exactly one hour.

3. How should batteries be maintained and stored?

Store Phantom 4 RTK batteries in a dry place away from water. If stored for a long time, keep the power supply at 50% or higher. And to maintain the functionality of the battery, it should be discharged every three months.

4. If the battery icon in the app turns yellow, what does that mean?

This indicates that the power supply voltage level is now below 3.62 V and should be recharged soon.

5. Will the Phantom 4 RTK batteries work in cold temperatures?

At low temperatures (below 10 degrees Celsius), the battery capacity (and therefore the flight time of the drone) drops dramatically. To reduce the influence of the cold temperature factor, we recommend warming up the batteries to 20 degrees Celsius before flying.

6. Why do batteries get hot after being stored for a long time?

This is a completely natural, normal phenomenon. If the batteries have been stored for a long time at a charge level above 65%, then in this case, the discharge procedure is automatically activated to reduce the level to 65%. This process leads to heating of power sources.

RTK position and photo position

1. What options does the user have to get positioning data from the Phantom 4 RTK?
  1. You can use the local connection through the OcuSync system to the D-RTK 2 mobile station. (RTCM3.2)
  2. You can use remote connection via 4G router to custom RTK network using NTRIP account.(RTCM3.2)
  3. You can also remotely connect via WiFi access to a custom RTK network using an NTRIP account. This option is not available in Europe. (RTCM3.0/RTCM3.1/RTCM3.2)
2. What is the positioning accuracy of the Phantom 4 RTK?

Horizontal data accuracy with the Phantom 4 RTK is 1cm +1mm/km and vertical 1.5cm + 1mm/km.

3. What is the TimeSync system and how does it ensure the positioning accuracy of each frame received from the Phantom 4 RTK?

The TimeSync system is responsible for the constant alignment of the flight controller, camera, and RTK module. It then corrects the positioning data by placing it in the center of the CMOS sensor and rewrites the data from EXIF ​​to XMP.

4. What is the difference between PPK and RTK modes and how to use them correctly?

RTK and PPK are two different kinematic technologies that refer to data in different ways. While PPK typically has better positional accuracy than RTK, both technologies achieve centimeter accuracy. RTK technology will be useful for those users who use aerial photography and real-time connection through the OcuSync system or 4G router, which generally provides a convenient and efficient operation. If the user does not care about the amount of time spent on research and / or there is a need to work without a connection, then PPK technology will be the best choice.

5. How can I find XMP information in photos taken from the Phantom 4 RTK?

You need to open a snapshot in text format and look for the abbreviation “XMP” which will help you find this information in each file.

6. If you are taking photos from a Phantom 4 RTK, where can you find the location metadata recorded during the photo?

To do this, the new drones are equipped with the TimeSync system, which helps to store location information from the center of the CMOS matrix in each photo in its metadata.

7. How can I get the correction value between the phase center of the antenna and the center of the CMOS array?

For each photograph, the correction value between the phase center of the RTK module antenna and the center of the CMOS matrix in the NED (North-East-Down) coordinate system is recorded in the timestamp.MRK file, which is located in the “survey” folder.

Software

1. How can I update the Phantom 4 RTK firmware?

The process for updating the firmware of the new Phantom 4 RTK model is almost the same as for the Phantom 4 Pro. To separately update the firmware of the aircraft and the remote control, use the DJI Assistant 2 desktop app. You can also update the firmware of the aircraft and remote control, but at the same time, through the GS RTK app. To do this, you first need to connect the remote to the aircraft using an OTG and USB cable, and then follow the procedures in sequence according to the instructions in the GS RTK app on the remote.

2. When are the infrared sensors and left/right flight sensors activated?

Due to the fact that these sensors are currently not activated, the drone must be operated with the utmost care.

3. Which applications have got the function of mapping and inspection?

Users have access to a pre-installed GS RTK application that can be used for mapping or inspection. In addition, you can also install apps created with the DJI Mobile SDK.

4. Does the Phantom 4 RTK RTH (return to base) mode work differently from the Phantom 4 Pro?

No. In the new model, the principle of operation of the RTH mode is practically no different.

5. Are there any waypoint restrictions for the Phantom 4 RTK?

Yes, there is such a limitation and it consists in the fact that the distance between points should not exceed two kilometers, and the total number of such points should not exceed 99. In addition, the total length of the flight route should not exceed 15 km.

6. Can a user enter longitude and latitude points in Waypoint mode?

No.

7. If spatial KML files are imported using the GS RTK application, what is the maximum number of boundary points that can be set?

The GS RTK application currently supports up to 99 edge points in KML files.

mapping

1. What differential data formats does the Phantom 4 RTK system support?

The Phantom 4 RTK system currently supports RTCM 3.0 data, RTCM 3.1 data, MSM4 and MSM5 data in RTCM3.2.

2. Are the received Phantom 4 RTK coordinates relative or absolute?

The coordinates received by the Phantom 4 RTK are absolute in the coordinate system selected by the user.

3. How can I calculate the desired flight altitude based on the GSD value?

You can use the formula H = 36 * GSD to get the right value for the flight altitude. Please note that GSD (Ground Sampling Distance) in this formula is measured in centimeters, while H (Height or Flight Height) is measured in meters.

4. Does the Phantom 4 RTK capture capture altitude information? If yes, how is this data stored?

Climb and relative flight altitude data (relative to base parameters) is stored in images created by the Phantom 4 RTK. Altitude settings can be used for mapping, while relative elevation data is in an XMP file.

5. How can the Phantom 4 RTK capture perspective aerial topography images?

For aerial photography, use the Photogrammetry mode in the GS RTK app. In this mode, the user can adjust the suspension angle in the range of -90 ° and -45 °. This can be done in the Camera Settings submenu for the flight plan. The user can only set one gimbal angle at a time, so for locations that need to set several different tilt angle settings, you can schedule a repeat mission and adjust the camera angle.

6. Can I create a 3D model or point cloud using third party software and frames generated by the Phantom 4 RTK? If so, what would be the accuracy of such a model?

Yes, the user can use third party software to process the image data acquired with the Phantom 4 RTK and create models. However, the accuracy will vary depending on the photogrammetry algorithm used. To do this, we recommend that you first obtain information from a third-party manufacturer about the degree of accuracy.

7. What is the best method to use on the Phantom 4 RTK to map narrow sections of terrain?

When collecting data on infrastructure or other narrow terrain compartments, we suggest that you set a high overlap ratio, fly the aircraft higher than normal, and plan at least two flight paths for the entire compartment.

8. Is the Phantom 4 RTK compatible with third party base stations?

No. You will not be able to connect third party base stations to the Phantom 4 RTK or radio remote control. However, you can receive data from the RTK network server through the Ntrip protocol on a 4G/Wi-Fi network. Satellite data can also be stored on the aircraft for post-processing kinematics (PPK) as part of the mission.

Phantom 4 RTK SDK

INCREDIBLY SMART. AMAZINGLY ACCURATE. HIGH PERFORMANCE

Phantom 4 RTK. Incredibly smart. Amazingly accurate. high performance

Phantom 4 RTK. The last word in cartography and geodesy

The last word in cartography and geodesy

True professionals in the field of cartography and geodesy will appreciate this compact, incredibly smart and highly accurate drone. This is a new product from DJI – Phantom 4 RTK SDK. Its new module that provides you with the best data, as well as a high-performance image processing system, along with other features, make it an ideal choice for surveying and mapping work.

Phantom 4 RTK. Mapping with incredible accuracy

Mapping with incredible accuracy

Although DJI has previously released aircraft that have been equipped to create maps with a high degree of accuracy, the introduction of the Phantom 4 RTK SDK was the next step in the development of such technologies and quality standards in the field of surveying. The equipment of the drone helps the user to obtain information in which the accuracy of the parameters is verified to the centimeter. At the same time, the drone flight route is built according to the most optimal scheme.

Horizontal Accuracy

The use of the RTK method allows to achieve the highest degree of horizontal positioning: 1 cm + 1 md.

Vertical Accuracy

The use of the RTK method also allows achieving high vertical positioning accuracy: 1.5 cm + 1 md

Professional photo and video

Photogrammetric Model Accuracy

Aerial survey using the RTK method gives the absolute accuracy of the photogrammetric model horizontally: 5 cm.

Phantom 4 RTK. High precision and safety

High precision and safety

Unlike DJI industrial platforms, the Phantom 4 series models have never been equipped with RTK modules before. The new modification of the famous fourth series, on the contrary, received such equipment for the first time, which gave it new properties. Such a model is sure to attract the attention of professionals, because in addition to a powerful camera and extensive post-processing capabilities, it guarantees the receipt of accurate data on the location of the drone in real time, moreover, with unprecedented accuracy (1 cm) and a minimum error in image metadata.

However, the benefits of the Phantom 4 RTK don’t stop there. The presence of an RTK module is important, but it is equally important to ensure safe piloting, especially in conditions of strong interference and weak signal, which are usually characteristic of urban environments. Therefore, in addition to the RTK receiver, the Phantom 4 RTK SDK is equipped with a satellite positioning system module. The use of two modules at once – RTK and a satellite systems module – gives a synergistic effect, enhancing the safety of piloting and the degree of accuracy of information for performing geodesy, cartography and inspection tasks.

Phantom 4 RTK. Efficient and convenient integration

Efficient and convenient integration

Flexibility and the ability to integrate a range of developments into workflows is a hallmark and advantage of many DJI products. The Phantom 4 RTK SDK is no exception, as its capabilities can be easily integrated into almost any workflow. It is enough to connect the positioning system to the D-RTK 2 mobile station. To do this, you can use a 4G modem or a WiFi wireless connection and the NTRIP protocol (implies RTCM network transmission via the World Wide Web). The user also gets the option to save the satellite data with the system for future processing.

Phantom 4 RTK. TimeSync system

TimeSync system

The TimeSync system used on the Phantom 4 RTK integrates several important components at once: the flight controller, camera, and RTK module. This greatly improves the efficiency of the geo-positioning module on the drone. However, TimeSync’s tasks are not limited to this, as it is also responsible for using the most accurate metadata of each frame and moving positioning data to the CMOS center. This feature helps to optimize the results of photogrammetric technology, and also helps to obtain location information with the highest accuracy – up to 1 cm.

Phantom 4 RTK. Image Processing Accuracy

Image Processing Accuracy

It is not enough to know exact location data. The high quality of cartography or object data is highly dependent on the capabilities of the imaging system. The Phantom 4 RTK SDK capture system inherits the best of its predecessors: a 20MP 1.0-inch CMOS sensor for high-quality footage, a mechanical shutter to prevent blurry shots when shooting on the move, and other advantages.

Therefore, whatever tasks you solve – creating maps or simply collecting the data you need – everything will be done perfectly. The high resolution will help you achieve a ground resolution of 2.74 cm at a flight altitude of 100 m. And because you need maximum accuracy, a calibration process will be performed for each lens of the system, including measurement of radial and tangential distortion. The resulting distortion data will be stored in the frame metadata so that during post-processing, each shot can be approached individually.

GS RTK App

DJI always strives to make the operation of its drones, and even more so for professional purposes, as convenient and safe as possible. In this case, a special GS RTK application has been developed for such tasks, which will not only help manage the Phantom 4 RTK SDK, but also greatly facilitate the performance of special tasks. For example, you can use the Photogrammetry and Waypoint Flight modes to improve your work efficiency. The application in this way will automate the compilation of the route and the flight along it, and will also simplify the regulation of the degree of overlapping frames, speed and other parameters. These and a number of other features will allow you to carry out the mapping or inspection procedure much faster without compromising quality. The functionality of the application allows you not only to plan a flight and control the operation of the camera,

OcuSync system

This system has been working on the latest DJI models for several years now and has earned only positive feedback from pilots. The reasons become clear if you look at the OcuSync functionality, which allows you to ensure safe piloting and transmission of video images at a distance of up to 7 km. The system can be especially useful if you have to work on a large area. However, it should be borne in mind that the parameters of the system largely depend on the specific piloting conditions and weather conditions. Still, it is recommended – and it is even spelled out in the regulations of a number of countries – to keep the drone in sight, unless otherwise permitted by law.

Compatible with D-RTK 2

For future users of the DJI Phantom 4 RTK SDK, it will be useful to know that the new model is compatible with the D-RTK 2 mobile station, which helps to transmit a differential signal to the aircraft in real time. For cartography, this is of great importance, since in this case accurate data is obtained. An even more important factor can be considered the joint operation of the mobile station and the OcuSync 2.0 transmission system, as a result of which the aircraft receives and transmits information in which the positioning accuracy reaches 1 cm, and in almost all circumstances.

Phantom 4 RTK. Mobile SDK

Mobile Service SDK

DJI is always open for cooperation, especially when it comes to creating professional applications. When you purchase the Phantom 4 RTK SDK, you get a huge amount of power thanks to its compatibility with DJI’s Mobile SDK. It will allow you to quickly and easily automate and optimize the operation of the drone itself and its components using a mobile gadget.

The characteristics of speed, time and range provided by the manufacturer are the result of laboratory tests and are for informational purposes only. In a real situation, flight performance may vary depending on the conditions in which the flight is carried out.

1. What is the difference between the Phantom 4 RTK and previous models in the Phantom series?

The main difference lies in the range of tasks that the old models of the Phantom series are designed to solve. These drones have been developed mainly for use by professional photographers and casual drone enthusiasts. The new Phantom 4 RTK, on ​​the other hand, was built for industrial applications such as high-precision mapping and data collection for a variety of purposes. There are also differences in equipment. If the camera capabilities and even the dimensions of the aircraft of the latest models of the Phantom series are similar, then the previous models do not have an RTK module, but the new Phantom 4 RTK model is equipped with such a device. In addition, it has a completely new TimeSync system for the famous DJI series, as well as a dedicated mapping application and other related components.

2. What propellers does the Phantom 4 RTK have?

The new Phantom 4 RTK features the same propellers as the previous Phantom 4 Pro, the 9450s quick release propellers.

3. Can the Phantom 4 RTK be operated in other countries and regions?

The Phantom 4 RTK has been developed in several versions, which are accordingly suitable for operation in various countries and/or regions. Users need to check the version code on the product packaging or use the GS RTK app to do this (go to the “Aircraft Information” menu and go to the “Firmware / Firmware” section).

Camera

1. What are the main differences between the camera of the new Phantom 4 RTK model and those on the Phantom 4 Advanced/Pro models?

The Phantom 4 RTK and the previous Phantom 4 Pro/Advanced share a number of camera features: they are equipped with a 1-inch 20-megapixel CMOS sensor. However, due to the Phantom 4 RTK’s specialization in mapping and geodetic work, its camera has received improved performance. It is equipped with a new lens distortion recording function. This means that every Phantom 4 RTK camera goes through a calibration process to measure lens distortion, resulting in the corresponding OPEN-CV parameters being recorded. Thus, users can get both original frames without distortion correction, and OPEN-CV distortion parameters in XMP format file. In the latter case, it will come in handy to perform the post-processing process.

2. Will the Phantom 4 Pro ND filters work with the Phantom 4 RTK camera?

Yes. The design and dimensions of these filters are fully compatible with the Phantom 4 RTK camera.

3. Does the Phantom 4 RTK digital signal processor support distortion correction?

No. You won’t be able to correct the distortion in-camera, and the shots will be less accurate than those that have been de-distorted with post-processing software.

Remote control

1. What are the main differences between the new Phantom 4 RTK remote control and the Phantom 4 Pro remote control?

The Phantom 4 RTK remote control has received a number of new features and interface elements that make it more versatile and more suitable for industrial applications. Among these changes, the appearance of a slot for Micro-SD cards, the presence of a built-in speaker, as well as hot-swappable batteries. In addition, the remote control has the function of connecting via the Internet to the RTK (Network RTK) network using a 4G router. And so that the user can start collecting data quickly, each remote comes preloaded with the new GS RTK app.

2. Is it technically possible to use the remote control of any Phantom 4 Advanced/Pro to control the Phantom 4 RTK drone?

No, there is no such possibility. You cannot control the Phantom 4 RTK with the Phantom 4 Advanced or Pro remote control.

3. How can I switch between US (FCC) and European (CE) modes?

The function to switch between FCC and CE modes is not available.

4. How to properly connect the remote control to the Phantom 4 RTK?

For this operation, you need to use the GS RTK app. To learn more about this, please refer to the User’s Guide.

Broadcast video

1. How far can the Phantom 4 RTK broadcast video?

The effective distance for video transmission depends on the method of performing this task, for example, on the position of the antenna, as well as on the external conditions of piloting. When flying in an open area free of obstacles, the maximum effective distance is 7 km (in FCC mode) and 4 km (in CE mode) at 2.4 GHz.

2. What should I do if the application gives the following message: “the signal of the remote control is weak, it is necessary to adjust the antenna”?

This message indicates an incorrect position of the antenna, which, most likely, affected the video broadcast signal, and, as a result, the quality of the live video. You should try to adjust the antennas so that their flat sides are facing the Phantom 4 RTK.

3. Is it possible to continue the automatic mapping mission if the Phantom 4 RTK loses the video broadcast signal during it?

Yes, this is quite possible, because if the signal is lost, you can reconnect and continue performing tasks.

Battery

1. Can Phantom 4 Pro batteries be installed on the new Phantom 4 RTK drone and vice versa?

Since the power supplies from the two models – Phantom 4 RTK and Pro – are cross-compatible and have the same capacity, this can be done. This will not affect the flight parameters in any way.

2. How long does it take to fully charge the Phantom 4 RTK power supply?

When the Phantom 4 RTK battery is fully charged, the procedure will take exactly one hour.

3. How should batteries be maintained and stored?

Store Phantom 4 RTK batteries in a dry place away from water. If stored for a long time, keep the power supply at 50% or higher. And to maintain the functionality of the battery, it should be discharged every three months.

4. If the battery icon in the app turns yellow, what does that mean?

This indicates that the power supply voltage level is now below 3.62 V and should be recharged soon.

5. Will the Phantom 4 RTK batteries work in cold temperatures?

At low temperatures (below 10 degrees Celsius), the battery capacity (and therefore the flight time of the drone) drops dramatically. To reduce the influence of the cold temperature factor, we recommend warming up the batteries to 20 degrees Celsius before flying.

6. Why do batteries get hot after being stored for a long time?

This is a completely natural, normal phenomenon. If the batteries have been stored for a long time at a charge level above 65%, then in this case, the discharge procedure is automatically activated to reduce the level to 65%. This process leads to heating of power sources.

RTK position and photo position

1. What options does the user have to get positioning data from the Phantom 4 RTK?
  1. You can use the local connection through the OcuSync system to the D-RTK 2 mobile station. (RTCM3.2)
  2. You can use remote connection via 4G router to custom RTK network using NTRIP account.(RTCM3.2)
  3. You can also remotely connect via WiFi access to a custom RTK network using an NTRIP account. This option is not available in Europe. (RTCM3.0/RTCM3.1/RTCM3.2)
2. What is the positioning accuracy of the Phantom 4 RTK?

Horizontal data accuracy with the Phantom 4 RTK is 1cm +1mm/km and vertical 1.5cm + 1mm/km.

3. What is the TimeSync system and how does it ensure the positioning accuracy of each frame received from the Phantom 4 RTK?

The TimeSync system is responsible for the constant alignment of the flight controller, camera, and RTK module. It then corrects the positioning data by placing it in the center of the CMOS sensor and rewrites the data from EXIF ​​to XMP.

4. What is the difference between PPK and RTK modes and how to use them correctly?

RTK and PPK are two different kinematic technologies that refer to data in different ways. While PPK typically has better positional accuracy than RTK, both technologies achieve centimeter accuracy. RTK technology will be useful for those users who use aerial photography and real-time connection through the OcuSync system or 4G router, which generally provides a convenient and efficient operation. If the user does not care about the amount of time spent on research and / or there is a need to work without a connection, then PPK technology will be the best choice.

5. How can I find XMP information in photos taken from the Phantom 4 RTK?

You need to open a snapshot in text format and look for the abbreviation “XMP” which will help you find this information in each file.

6. If you are taking photos from a Phantom 4 RTK, where can you find the location metadata recorded during the photo?

To do this, the new drones are equipped with the TimeSync system, which helps to store location information from the center of the CMOS matrix in each photo in its metadata.

7. How can I get the correction value between the phase center of the antenna and the center of the CMOS array?

For each photograph, the correction value between the phase center of the RTK module antenna and the center of the CMOS matrix in the NED (North-East-Down) coordinate system is recorded in the timestamp.MRK file, which is located in the “survey” folder.

Software

1. How can I update the Phantom 4 RTK firmware?

The process for updating the firmware of the new Phantom 4 RTK model is almost the same as for the Phantom 4 Pro. To separately update the firmware of the aircraft and the remote control, use the DJI Assistant 2 desktop app. You can also update the firmware of the aircraft and remote control, but at the same time, through the GS RTK app. To do this, you first need to connect the remote to the aircraft using an OTG and USB cable, and then follow the procedures in sequence according to the instructions in the GS RTK app on the remote.

2. When are the infrared sensors and left/right flight sensors activated?

Due to the fact that these sensors are currently not activated, the drone must be operated with the utmost care.

3. Which applications have got the function of mapping and inspection?

Users have access to a pre-installed GS RTK application that can be used for mapping or inspection. In addition, you can also install apps created with the DJI Mobile SDK.

4. Does the Phantom 4 RTK RTH (return to base) mode work differently from the Phantom 4 Pro?

No. In the new model, the principle of operation of the RTH mode is practically no different.

5. Are there any waypoint restrictions for the Phantom 4 RTK?

Yes, there is such a limitation and it consists in the fact that the distance between points should not exceed two kilometers, and the total number of such points should not exceed 99. In addition, the total length of the flight route should not exceed 15 km.

6. Can a user enter longitude and latitude points in Waypoint mode?

No.

7. If spatial KML files are imported using the GS RTK application, what is the maximum number of boundary points that can be set?

The GS RTK application currently supports up to 99 edge points in KML files.

mapping

1. What differential data formats does the Phantom 4 RTK system support?

The Phantom 4 RTK system currently supports RTCM 3.0 data, RTCM 3.1 data, MSM4 and MSM5 data in RTCM3.2.

2. Are the received Phantom 4 RTK coordinates relative or absolute?

The coordinates received by the Phantom 4 RTK are absolute in the coordinate system selected by the user.

3. How can I calculate the desired flight altitude based on the GSD value?

You can use the formula H = 36 * GSD to get the right value for the flight altitude. Please note that GSD (Ground Sampling Distance) in this formula is measured in centimeters, while H (Height or Flight Height) is measured in meters.

4. Does the Phantom 4 RTK capture capture altitude information? If yes, how is this data stored?

Climb and relative flight altitude data (relative to base parameters) is stored in images created by the Phantom 4 RTK. Altitude settings can be used for mapping, while relative elevation data is in an XMP file.

5. How can the Phantom 4 RTK capture perspective aerial topography images?

For aerial photography, use the Photogrammetry mode in the GS RTK app. In this mode, the user can adjust the suspension angle in the range of -90 ° and -45 °. This can be done in the Camera Settings submenu for the flight plan. The user can only set one gimbal angle at a time, so for locations that need to set several different tilt angle settings, you can schedule a repeat mission and adjust the camera angle.

6. Can I create a 3D model or point cloud using third party software and frames generated by the Phantom 4 RTK? If so, what would be the accuracy of such a model?

Yes, the user can use third party software to process the image data acquired with the Phantom 4 RTK and create models. However, the accuracy will vary depending on the photogrammetry algorithm used. To do this, we recommend that you first obtain information from a third-party manufacturer about the degree of accuracy.

7. What is the best method to use on the Phantom 4 RTK to map narrow sections of terrain?

When collecting data on infrastructure or other narrow terrain compartments, we suggest that you set a high overlap ratio, fly the aircraft higher than normal, and plan at least two flight paths for the entire compartment.

8. Is the Phantom 4 RTK compatible with third party base stations?

No. You will not be able to connect third party base stations to the Phantom 4 RTK or radio remote control. However, you can receive data from the RTK network server through the Ntrip protocol on a 4G/Wi-Fi network. Satellite data can also be stored on the aircraft for post-processing kinematics (PPK) as part of the mission.

The data obtained by P4 Multispectral channels can be used for various crops and plants. Vegetation index maps such as NDVI or NDRE can be reconstructed for plant health monitoring using DJI Terra or third party applications.

2. Can I do scheduled inspections with the P4 Multispectral?

Yes, you can plan flight routes and repeat them with GS Pro.

3. Can maps be reconstructed using third party software?

Yes.

4. How to calculate flight altitude using ground resolution (GSD) value?

The GSD for P4 Multispectral is (H/18.9) cm/pixel. The flight altitude can be calculated according to the accuracy you require.

5. What is the max. area of ​​land that can be processed in one flight?

Max. the area is about 0.47 km2 per flight at 180 m, i.e. the ground resolution is about 9.52 cm/pixel.

6. Do waypoints contain flight altitude information?

Relative altitude information (relative to the takeoff point) is stored in pictures captured as waypoints.

7. Is the P4 Multispectral compatible with third party base stations?

No. Third-party base stations cannot be connected to the P4 Multispectral or remote control via radio. However, the data can be accessed through the RTK network server using a 4G or WiFi modem using the NTRIP protocol. Satellite data can be stored by aircraft users for further processing of the kinematics.

    Since purchasing this aircraft, DJI have started to include features that may, long term, reduce the functionality of the aircraft and allow further restrictions on where it can be flown to be put in place. I can understand why they have done this as there is a lot of media attention on irresponsible use of these machines – however, it does give the distinct impression that DJI believe they continue to have some degree of ownership of the device after is has been purchased.

    In Europe and the States at least, these updates are not (yet) mandatory.

    DJI have been slow and apparently reluctant to properly explain the purpose of these updates.

    I still believe the Phantom 4 Pro deservers a 5 star review, but I would suggest doing a bit of research before purchasing to ensure you are happy with the way DJI handles software updates and legislative compliance.

    Original review below
    —————————

    I’ve wanted a full size quadcopter for years, and I finally decided to buy the Phantom 4 pro.

    The first thing that strikes you on unpacking this aircraft is the quality of construction – it looks and feels solid, and about as far from being a ‘toy’ as you can imagine.
    The batteries were pretty discharged when it arrived, so the first thing was to charge the flight battery and controller to 100% before getting on with setting up the application.

    Once the battery was fully charged, I downloaded the ‘DJI assistant 2’ app to my PC and updated the firmware on the quadcopter.

    Next step was to install the DJI Go 4 app on my tablet (a Sony Xperia Z4) – and this was the only step where things didn’t go too smoothly.
    The tablets clamps snugly onto the controller, and connects to it with a standard USB cable – however, the Xperia didn’t detect the controller and I was faced with a ‘disconnected’ message.. A bit of Googling showed that this is a common problem with some tablets, and there is a workaround using the hidden Android Developer menu to force the tablet to detect the USB device.

    After connecting the controller, the next step was a controller firmware update (done via the App) – and, following that, an IMU calibration which requires you to put the Phantom on a flat surface and follow instructions to allow it to remove ‘drift’ from the IMU.
    I also took the opportunity to set the maximum height to a sensible limit (I chose 80m).
    I should also note that at this point, I registered for DJI’s ‘Phantom care’, which means that in the event of a catastrophic crash, I could purchase a replacement machine for less than £200.

    So, after all this and a fresh charge, the only thing to do was to find an open field with no people about for the first flight… Not so easy on Boxing day!

    Having finally found an open field, I fitted the blades to the Phantom – this is an easy job, you just push them on and rotate to lock – it takes less than a minute.
    Next, I used the Styrofoam case as a handy launch pad – set the Phantom on it, powered everything up and waited for the app to tell me that the home location had been registered – this is a very important step if you don’t want to lose your expensive aircraft on its first flight!
    Before flying, I set the ‘return to home’ height in the app to 35m, which I chose to be considerably higher than any obstacles nearby.

    So, having done this – I pressed the ‘launch’ button on the app, and swiped to indicate ‘yes, I really do want to launch’… immediately the motors do a little check and next the quadcopter lifts off and hovers, rock solid, at about head height… despite some fairly strong wind which the app warned me about.

    Next I applied some throttle and immediately the Phantom climbed absolutely vertically, until I let go of the left stick at which point it stopped. What amazed me was the despite some fairly strong breeze, the video coming back was absolutely rock solid.

    Having got a feel for how stable the aircraft was, I did a few circuits around the field, and then tried the ‘return to home’ function.
    This works very, very well – the Phantom climbed up to the pre-set height and then flew back to directly over its launch point – at which point the app told me is was descending..
    The Phantom began to descend quite slowly until it was a few metres above the ground – and then it hovered for a while before telling me that the location was not suitable for landing… this was spot on, as there was some tall grass. It was a fairly easy job to take over manually at this point and move to a flatter spot where I carried out a completely hassle free landing.

    So – having only flow some small ‘toy’ quadcopters before, I was amazed at how easy this thing is to fly, and how absolutely stable it remains when there are no control inputs – it’s almost like magic. I am very, very impressed.

    I spent the rest of my first session taking slightly longer flights, and experimenting with the advanced flight modes – such as Active Track, which worked incredibly well – until after about 25 minutes of flying I got the first battery warning, and used the ‘Home’ button to finish the flight.

    So all in all, I am amazed by this machine – yes, it’s very expensive – but if you want a real aircraft that can take beautiful video and stills, with easy handling and very quick setup / packing then this is the machine for you. It’s just incredible.

    UPDATE: 05-01-17

    Having used the P4P for a few days, I have noticed some problems with the video recording.
    The video on my unit ‘stutters’ during a pan, and occasionally the gimbal will twitch during flight.
    Having done a bit of research, it seems there are some known problems with the gimbal seembly on the early batches of the Phantom 4 Pro – I will be returning mine for an exchange when it’s back in stock.

    i will still give the P4P a five star rating – the issues are fairly minor (but shouldn’t exist on a product at this price) – and many people seem to have no problems at all.

    So, I would strongly recommend waiting a few months before buying to ensure you get one from a newer batch.

    It’s worth mentioning that Amazon have been excellent and have offered a full refund as the product is currently out of stock.

    UPDATE 15-01-17

    I have received a new Phantom 4 pro which has had the Gimbal issue rectified.

    This drone flys almost everyday and gets great results every time. 4k video is sharp and smooth and the quality exceeds my client’s expectations.

    This thing is great – going to give a full review within a few days, but (for me first drone) this thing is easy to fly, and being a photographer anyway, the quality of the image/video was essential – saving the £400 for the cheaper (none-pro) Phantom 4 is NOT worth the saving, unless you are happy with smart phone quality images, the Pro version (this one) I’d equate the image quality, roughly, to that of a Nikon D3200 – and as for the video quality – WOW – I have never owned a product that can shoot 4K @ 60FPS and look THAT good.

    If you intend on doing any low light work (indoors, just pre sunrise/post sunset or night flying, the, this version, the Phantom 4 Pro is essential. I’m going to take a wild guess here, and say, at least to You and I, the regular Phantom 4 (appx £1000) – you’re paying no more than £100 for the camera bit, at the MOST, and for the Phantom 4 Pro, I’d guess, you’re paying most of that £440, towards the better camera. Again, I am guessing, but if you’re buying a flying camera, you may as well pay 40% more cost, for 400% more camera. That’s all my personal guesstimated opinion, but why strap a 50 pence plastic case to a £700 smart phone?

    As you can see by my stars, this is not a toy and its not easy to learn. I would recommend it as an upgrade to someone who has already cut their teeth on another drone. Frankly, I have had it for awhile now and I am still learning all it features. One thing that impresses my and everyone who see video or still is the resolution and quality of the camera. This thing takes awesome footage and stills. Its also pretty tough as I have crashed it a few times in the process of learning and am about due for new props. I use it to fly over woods in search of historical items, bridges, homesteads and the like. Works really well for this and helps me to determine where I can search in person if it turns something up. Nice piece of gear.

    An amazing quadcopter. I write this a user of the Phantom 2 (with GoPro) so have some prior experience in flying and filming sequences.

    Why 3 stars? Because the video is technically flawed. I’ve shot at 60fps on 4k and every now and then, the image jutters/jumps. I don’t know if this is a software issue in the recording of information, or if the camera itself jumps microscopically every now and then. Either way, it’s an issue with this quadcopter and ruins a perfectly good video sequence. I will be conducting a few other test shoots on other settings to see if the problem is replicated. If it isn’t, then it’s possibly a software issue when recording at 60fps in 4k. If it does still occur, then it’s either of the two problems mentioned earlier. I’ll investigate a replacement with Amazon regardless.

    The main reason I bought this is because the photos can be shot in RAW (DNG) format, and as a photographer, this is a must. At only 20MP and with a dynamic range far more limited, it’s a step down from my DSLR. There is grain in even the lowest of ISO settings too, but in good light, it’s not distracting. However, for the cost of this quadcopter, it allows for aerial photography that is otherwise out of my budget and so will do for now.

    On to the good stuff. The DJI software is exceptional and worlds away from flying the Phantom 2. I purchased the non-Pro Plus edition as I felt the included screen was too small (despite the benefits in its brightness) and opted for the normal Pro version. I use an iPad to run the DJI software (although the brightness isn’t anywhere near as usable in bright sunlight) because the screen is far larger and I have the option to use third party software like Litchi. The signal from the quadcopter to the remote is amazing and the app comes with differing functionality, much of which is a gimmick in my opinion and therefor is somewhat limited in scope and use. The true joy and purpose of the quadcopter is to fly and record, so whatever floats your boat, be it free flight, or using automated features, you’ll find something you like in the Phantom 4 Pro, especially if using Litchi.

    Setup is a breeze, flying is a breeze and the app is well enough designed that you’ll figure out where options are and how to access them with a bit of use.

    It’s a shame that the Phantom 4 Pro, at least mine, is affected by this glitch in recording.
