Phantom 4 RTK

With a brand-new RTK module fitted into the top of the drone, the built-in centimetre-level navigation and positioning system can provide real-time data with 3cm accuracy. Paired with a redundant GNSS module, it is able to gain accurate results from stabilised flight even in areas with weak mobile network coverage. The D-RTK 2 mobile station can be also connected with this fully-integrated system, to achieve even more accurate results in areas with poor mobile network coverage.

Setting up ground control points can become a thing of the past, with only 0-5 GCPs required when deploying the Phantom 4 RTK. Without GCPs, the achievable horizontal accuracy is up to 3cm and vertical accuracy up to 5cm.

Although featuring the same 1-inch, 20MP CMOS sensor as the Phantom 4 Pro, the Phantom 4 RTK camera allows the operator to produce the original imagery minus distortion correction, providing more precise images for post-processing. Mapping accuracy meets the requirements of the ASPRS Accuracy Standards for Digital Orthophotos Class III.

The new TimeSync system works to simultaneously align the flight controller, camera and RTK module, whilst matching the positioning data to the centre of the 1-inch CMOS sensor. The Phantom 4 RTK will fly across complex terrain from a specified static height and has the ability to do so turning through the pre-set route at a consistent speed. The operator also has the ability to select and amend the flight path, at the same time adjusting altitude, speed, overlap rate and camera settings (to name a few!) – making drone mapping easier and more efficient than ever before.

All of this can be achieved within an extended battery life of 30 minutes, allowing the operator to map large areas per flight. Should the batteries require replacing/recharging during a flight, afterward the flight mission is automatically resumed due to the Operation Resumption function of the GS RTK App.

When processing the captured data, images can be used to create multiple industry-acceptable deliverables, including; point cloud classification, vectorisation, BIM (building information modelling), and volume/mass calculation.

DJI Phantom 4 RTK + D-RTK 2 Mobile Station + DJI TERRA

How do I purchase DJI Terra?
DJI Terra Advanced and Pro can be purchased through authorised DJI resellers. Contact Uplift Drones on 0330-111-8800 or email info@upliftdrones.com for pricing.
For how long will my DJI Terra license be effective?
The DJI Terra Advanced and Pro plans are only valid for one year .
Your license comes into effect starting the day the device is bound to DJI Terra.
What do I need to start using DJI Terra?
1. A Phantom 4 Series drone that supports DJI Terra, several batteries;
2. A laptop, a microSD card and a card reader;
3. A compatible cable (a USB-to-USB cable for Phantom 4, Phantom 4 Pro, Phantom 4 Advanced, a Micro-USB cable for Phantom 4 Pro+ V2.0, a USB-C cable for Phantom 4 RTK.)
How many computers can be bound to the same account?
Each activation code can be used with a DJI account to activate a license, which can be bound to a maximum of 3 Windows computers. The binding will be permanent and once bound, cannot be unbound.
What are the computer system requirements for 2D and 3D reconstruction with DJI Terra?
A Windows 7 or above (64 bits) system is required when using DJI Terra.
Minimum hardware configuration: 16GB RAM and a NVIDIA graphics card with at least 4GB VRAM.
Recommended hardware configuration: at least 32GB RAM and at least a NVIDIA 1050 Ti.
With these configuration requirements met, every additional 10GB of RAM will be able to process 1000 additional 4K images. The higher the system configurations, the larger the number of images that can be processed and the faster the reconstructions. The results from the models generated will not be affected by different hardware configurations.
Which aircraft are supported by DJI Terra?
Phantom 4 RTK, Phantom 4 Pro V2.0, Phantom 4 Pro+ V2.0, Phantom 4 Pro, Phantom 4 Advanced and Phantom 4. The Phantom 4 does not support 2D Real-time Mapping.
Can I still use the paid features of DJI Terra with no internet connection?
While connected to the internet, log into your account and bind a computer to the license so you can use the paid features of DJI Terra within the next 2 days even if you are not connected to the internet.
What is the difference between Waypoints Mission, Mapping Mission, and Oblique Mission?
Waypoints Mission: plan a flight route and capture photos or videos at waypoints along the route.
Mapping Mission: collect images of an area to reconstruct a 2D model.
Oblique Mission: collect images of an area from multiple camera angles to reconstruct a 3D model.
Why are there 5 flight routes when I plan an Oblique Mission in DJI Terra?
DJI Terra’s Oblique Mission uses 5 flight routes to capture the same amount of data as using 5 cameras simultaneously on a drone. The 5 flight routes correspond to the 5 camera headings – downward, forward, backward, leftward, and rightward.
How do I plan flight routes when there is no internet connection and the map cannot be loaded?
If you have access to a mobile device that has an internet connection (such as a cellphone), you can turn on the hotspot so that the laptop can be connected to the internet.
If the site where you are operating has no internet signal, you can pre-plan the flight route while you are indoors and have an internet connection, or manually fly the drone around the area to be mapped to set boundaries points to plan flight routes.
What is Ground Sample Distance (GSD)?
In photogrammetry and remote sensing, ground sample distance (GSD) in an aerial digital photo (such as an orthophoto) of the ground is the actual distance on the ground captured as represented by pixels. The unit is cm/pixel.
In the New Mapping Mission page, what does Relative Height in Advanced Settings mean? How is it different from Mission Altitude in Basic Settings?
Relative Height in Advanced Settings is the height of the takeoff point relative to the area being mapped. Mission Altitude is the height of the drone relative to the area being mapped, which is also how ground sample distance (GSD) is calculated.
When do I have to adjust the Relative Height in Advanced Settings?
When there is a large difference between the elevation of the takeoff location and the elevation of the area being mapped, you can adjust the Relative Height in Advanced Settings to ensure that the Mission Altitude is determined considering the elevation of the area being mapped.
What should I do to ensure accuracy in my missions when collecting data with the Phantom 4 RTK?
1) Conduct your missions in clear weather conditions with high visibility.
2) Check the images and videos for brightness and clarity immediately after your mission.
3) During a surveying mission, avoid areas with strong electromagnetic interference or obstructions to ensure the accuracy of the attitude algorithm of the Phantom 4 RTK. Also make sure that the remote controller is properly linked to the aircraft.
4) Ensure there is enough forward and side overlap. It is recommended to have a forward overlap rate of 80% and a side overlap rate of 70%. Overlap rates can be adjusted depending on the terrain.
When should I adjust the overlap rates based on the terrain?
It is recommended to have a forward overlap rate of 80% and a side overlap rate of 70%, which should meet the requirements for most application scenarios. The overlap rate can be increased when the area being mapped has a large difference in elevation to ensure the highest point mapped has enough overlap. When the area mapped is relatively uniform in elevation, the overlap rate can be adjusted lower to reduce the amount of data that needs to be processed, making the mapping mission more efficient. However, it is recommended to keep the forward overlap at a minimum of 65% and side overlap at a minimum of 60%.
When I connect DJI Terra to Phantom 4 RTK, the app tells me that I cannot take off because the RTK signal is too weak. What should I do?
It could be that you are operating somewhere with a lot of signal interference or obstructions, which affects the strength of the RTK signal. Try turning off the RTK module and take off manually with the GNSS positioning. Once the drone reaches a height where there is less interference, you can turn on the RTK module and connect to DJI Terra to conduct your flight missions.
Does DJI Terra support the marking of Ground Control Points (GCPs)?
Currently, DJI Terra does not support GCPs, but a similar mapping accuracy can be achieved by using DJI Terra with Phantom 4 RTK without marking GCPs.
Why is my computer stuck when processing images locally to reconstruct a model? Can I run DJI Terra while running other programs?
To build reconstruction models as quickly as possible, DJI Terra uses all the computer resources available, including the CPU, RAM, and VRAM of the graphics card, which could make the computer slower while running DJI Terra but should not be a problem once the processing is finished. It is recommended that you don’t run other programs that might be GPU-intensive while running DJI Terra, as doing so could result in failure of model reconstruction.
What are the Field, Urban, and Fruit Tree Scenarios in 2D Map?
The Field Scenario is designed to capture data from a relatively flat land, for example rice or wheat fields.
The Urban Scenario is designed for areas with buildings of different heights.
The Fruit Tree Scenario is designed for orchards that might have a large variation of elevations and heights. The 2D mapping algorithms are optimised for the three specific scenarios, so you can choose the one that best fits your mission type.
What projection is used to obtain the 2D mapping results in DJI Terra?
The map tiles in DJI Terra use the Web Mercator projection. The digital orthophoto map (result.tif) and digital surface model (dsm.tif) use the Universal Transverse Mercator (UTM) projection, where the projected zone number is calculated by taking the average of longitude coordinates collected.
Why is there a large discrepancy between the elevation result in the digital surface model (DSM) of the 2D map generated by DJI Terra and the actual elevation measured via RTK?
The location information on aerial images collected by a drone that’s not equipped with RTK is not the most accurate, which will result in a difference between the elevation in the digital surface model (DSM) and the actual elevation.

When conducting missions with the Phantom 4 RTK, if the 2D map is generated with only the Nadir view images collected, the precision of the DSM will be limited, which is why it is recommended to incorporate oblique imagery in building the 2D map to enhance precision. This can be done by setting the gimbal pitch to -45° and circling the point of interest during flight.

What is the difference between 3D Reconstruction in Mapping Mission and in Oblique Photography Mission?
There is no difference. If only Nadir view images are available, it is recommended to use a mapping mission for building 2D maps. If oblique photos are available, you can choose an oblique photography mission.
How different are the 3D models built at different resolutions? How long does it take to build models at these resolutions?
There are three options for reconstruction resolution: high, medium, and low, which will generate models at full, half, and quarter resolution respectively. The higher the resolution the better the quality of the reconstructed models. The rough ratio of time consumption for reconstruction at high:medium: low resolutions is about 16:4:1.
Why are there gaps in my model? What are some factors that affect the quality of the reconstruction?
Gaps in the model can be due to missing shots of the area being mapped, or images taken at poor angles. The quality of reconstruction can be affected by factors such as reflective surfaces in the area (water or glass), or large areas of the same color or pattern (white walls, skies).
Can I trim or edit the 3D models generated in DJI Terra?
Currently this function is not supported. If you would like to edit the model, you can export it and edit in another software.
What files can I get from the 2D maps and 3D models built in DJI Terra?
In addition to the map tiles shown in the app’s interface, DJI Terra’s 2D maps provide digital orthophoto maps and digital surface models in the GeoTIFF format used with UTM projection. DJI Terra’s 3D model reconstructions contain texture mesh in .ply format and level of detail model in .osgb or .b3dm formats.
How do I view the results and files from my 2D maps and 3D models?
You can click the More button in each Mission and open the file folders where the files generated from the missions are stored. You can also use Ctrl + Alt + F to quickly go to the folder. 2D maps are stored under “map” and 3D models are stored under “models”.
To view log files, use Ctrl + Alt + L.
What variables might affect the accuracy of the 2D and 3D reconstructions in DJI Terra?
The accuracy of the reconstruction can be affected by factors such as camera distortion, image quality, flight height, side and forward overlap settings, GPS (RTK) positioning accuracy and the area’s texture information.
What is the accuracy when building 2D maps and 3D models with the Phantom 4 RTK?
When using the Phantom 4 RTK, the absolute accuracy achieved by the 2D maps in DJI Terra is around 1 to 2 times the GSD, which is a similar level of accuracy as other data processing software. When flying at 100m height, the absolute horizontal accuracy of the 2D map is 2-5cm, and the absolute accuracy of the 3D models is within 4cm.
Which coordinate system and elevation are used for 2D and 3D reconstructions in DJI Terra?
The coordinate system used depends on the location of data collection. When using the Phantom 4 RTK to collect data, you can choose the coordinate system of the RTK module on the remote controller from the China Geodetic Coordinate System 2000 (CGCS2000), the World Geodetic System 1984 (WGS84, which is the default system), or a custom coordinate system. If you use another drone, the images collected have coordinates from the WGS84 system. The elevation of the data collected with the CGCS2000 and WGS84 system is the ellipsoid height.
Can I run multiple missions on the same computer?
Currently you cannot run multiple missions due to limitations in the computer’s processing capacity.
Can I import models generated in DJI Terra into other software programs, such as Maya, Blender, SketchUp, and 3ds Max?
When you convert .ply files generated in DJI Terra into .obj files, you can import them into Maya, Blender, SketchUp, and 3ds Max. Look up tutorials for the specific process for each software.
Can I embed a 3D model into a webpage?
Yes, .b3dm, .osgb, and .ply files generated by DJI Terra are universal file formats and can be embedded into webpages. You can find instructions for embedding each of these formats online.
Can I use non-aerial images to build 2D or 3D models?
Theoretically they can be used to reconstruct 3D models although the quality might suffer. They cannot be used to build 2D reconstructions.
Can I process images taken from non-DJI drones in DJI Terra to build 2D and 3D reconstructions?
Theoretically yes for 3D models, but the results might not be as good as if you were to use DJI drones. The quality of the reconstructions will benefit from GPS or RTK positioning data on the images. 2D reconstructions are not supported.
Which satellite positioning systems does the D-RTK 2 High Precision GNSS Mobile Station (D-RTK 2 Mobile Station) support?
The D-RTK 2 Mobile Station supports GPS, GLONASS, Galileo, and Beidou. It receives 11 satellite signals, including GPS L1, L2, L5; GLONASS L1, L2; Galileo E1, E5A, E5B and Beidou B1, B2, B3.
What is the difference between the D-RTK 2 Mobile Station and D-RTK?
There are 2 main differences: a. Physical differences: D-RTK is a module that includes 2 RTK receivers, antennas, and radio. One receiver can be used as the base station while the other as the rover station to transmit differential data via radio. D-RTK 2 Mobile Station is an all-in-one product that integrates a high-precision receiver and transmission links, making it easy to set up and use. b. Performance D-RTK has two versions that receive GPS+BDS or GPS+ GLONASS signals depending on the region of purchase. D-RTK 2 Mobile Station only has one version globally that supports four satellite navigation systems: GPS, BEIDOU, GLONASS, and Galileo, receiving 11 signals. The new antennas ensure better signal reception and higher positioning accuracy.
Which aircrafts is the D-RTK 2 Mobile Station compatible with?
It is compatible with Phantom 4 RTK, MG-1P RTK, and not with M210 RTK or D-RTK.
Why does the D-RTK 2 Mobile Station not support D-RTK?
Because the data links are different.
What does the D-RTK 2 Mobile Station do?
Currently it is a mobile RTK station, in the future it will be able to serve as a handheld mapping device and as a Continuously Operating Reference Station (CORS).
What are the power sources of the D-RTK 2 Mobile Station?
There are three power sources: 1. Internal battery WB37-4920mAh-7.6V 2. External battery (MG12000P) 3. AC power adaptor.
How long does the internal battery last?
At least two hours. The battery can be charged through the external power port on the D-RTK 2 Mobile Station, or removed and charged with the charger.
Does the internal battery need to be removed when the D-RTK 2 Mobile Station is not in use?
Yes. When not in use, please remove the battery. When powered off, the D-RTK 2 Mobile Station enters standby. If the battery is left in the D-RTK 2 Mobile Station, it will stand by for 10 days and then power off automatically to protect the battery, after which the battery needs to be changed or recharged.
Will the D-RTK 2 Mobile Station shut down when switching to an external power source?
When the internal battery is fully charged, the D-RTK 2 Mobile Station will stay on for at least two hours. If an external power source is connected before the internal battery is drained, the D-RTK 2 Mobile Station will continue to function, otherwise it will shut down.
Do I need to calibrate the D-RTK 2 Mobile Station with a reference point?
If there is a point with known location coordinates, simply place the D-RTK 2 Mobile Station exactly on that point then input the coordinates in the App. Make sure the difference in distance between the input and actual coordinates is less than 5 meters, or the input will not work.
How does the D-RTK 2 Mobile Station sense movement and determine if it is upright?
The D-RTK 2 Mobile Station is equipped with a high-performance IMU to monitor the status of the device and send that information to the aircraft. If the D-RTK 2 Mobile Station is moved or toppled over, the aircraft will stop performing RTK functions and display the status of the D-RTK 2 Mobile Station in the remote controller app.
How do I import a fixed set of coordinates into the D-RTK 2 Mobile Station?
This can be done in the remote controller app, please see the user manual for more information.
How do I run updates on the D-RTK 2 Mobile Station?
Log in to DJI ASSISTANT 2 with your DJI account, connect the D-RTK 2 Mobile Station to the PC with a Type-C cable and run the firmware update.
How does the Phantom 4 RTK differ from previous Phantom Series products?
While previous Phantom series drones were built around professional photographers and hobbyists, the Phantom 4 RTK was designed for industrial users for high-precision mapping and other data acquisition missions. While the Phantom 4 RTK shares a similar camera and form size, it also adds a RTK positioning module, a new TimeSync system, a purpose-built mapping app and more.
What propellers does the Phantom 4 RTK use?
The Phantom 4 RTK uses the same 9450s Quick Release Propellers as the Phantom 4 Pro.
Can I fly the Phantom 4 RTK in other countries or regions?
No, the Phantom 4 RTK has specific versions for different countries and/or regions. Users can check the version code on the product packaging or through the GS RTK app (go to Aircraft Information -> Firmware).
What is the difference between the Phantom 4 RTK’s camera and the camera on the Phantom 4 Advanced/Pro?
While the Phantom 4 RTK and Phantom 4 Pro/Advanced share the same 1-inch, 20 megapixel CMOS sensor, the Phantom 4 RTK has improved the capabilities of the camera for mapping through a new lens distortion recording process. Each Phantom 4 RTK camera goes through a calibration process that measures the distortions of the lens, and records the corresponding undistort parameters. The camera allows users to output the original images without distortion correction as well as the undistort parameters in the XMP file for post-processing
Can the ND filter of the Phantom 4 Pro be used on the Phantom 4 RTK?

Yes, the ND filters made for the Phantom 4 Pro can also be used for the Phantom 4 RTK.

Does the Phantom 4 RTK camera digital signal processor (DSP) support distortion correction?
No, you can enable the distortion correction in the camera but the images will be less precise compared to distortion elimination in post-processing software.
How is the Phantom 4 RTK camera calibrated?
Each Phantom 4 RTK camera goes through a calibration process that measures the distortions of the lens, and records the corresponding undistort parameters in XMP DewarpData. When the “distortion correction” is switched off, the original image with distortion will be generated. When the “distortion correction” is switched on, the parameters used to eliminate distortion is not the parameters calibrated, but the design parameters of the camera. When eliminating the distortions, it is not done pixel by pixel.
What are the highlight features for the standard remote controller of the Phantom 4 RTK?
1.Built-in 5.5-inch display, 1080P, up to 1000 nits brightness. You can see the screen in strong sunlight. The controller can work in low temperatures.
2.Supports hot swappable batteries.
3.Pre-installed GS RTK App can run Photogrammetry, Waypoint and other mission types.
4.OcuSync video transmission.
How can I switch between FCC and CE modes?
FCC and CE mode switching is not available.
Can I connect the Phantom 4 RTK to other Phantom series controllers?
No.
Can I continue my automated mapping mission if the Phantom 4 RTK loses video transmission signal during its mission?
Yes, if the video transmission signal is lost, you can reconnect and continue the mapping mission.
Can I use my Phantom 4 Pro batteries with the Phantom 4 RTK and vice versa?
Yes, the Phantom 4 RTK and Pro batteries are cross compatible and have the same capacity, meaning flight time won’t be effected.
How long does it take to fully charge a Phantom 4 RTK battery?
It takes roughly 60 minutes to fully charge a Phantom 4 RTK battery.
What options do I have to reference the positioning data from the Phantom 4 RTK?
1. Connect locally via OcuSync to your D-RTK 2 Mobile Station. (RTCM3.2)
2. Connect remotely via a 4G Dongle to a custom RTK network using a NTRIP account.(RTCM3.2)
3. Connect remotely via a WiFi hotspot to a custom RTK network using a NTRIP account. Not available in Europe.(RTCM3.0/RTCM3.1/RTCM3.2)
What positioning accuracy can the Phantom 4 RTK achieve?
The Phantom 4 RTK can achieve 1 cm+1 ppm (horizontal), 1.5 cm + 1 ppm (vertical) accurate data.
What is TimeSync and how does it ensure the positioning accuracy of each image taken on the Phantom 4 RTK?
TimeSync continually aligns the flight controller, camera and RTK module, then adjusts the positioning data to the center of the CMOS and records the data in EXIF and XMP format.
What apps have mapping or inspection function?
Users can use the pre-installed GS RTK app for mapping or inspection missions. Additionally, users can install apps built on DJI’s Mobile SDK.
What mapping platform is being used to provide map data to the Phantom 4 RTK app?
Mapbox is used to provide map data to the GS RTK app.
What formats of differential data does the Phantom 4 RTK support?
Currently the Phantom 4 RTK supports RTCM 3.0 data, RTCM 3.1 data, MSM4,MSM5, MSM6 and MSM7 data under RTCM3.2.
Are the coordinates measured by the Phantom 4 RTK relative coordinates or absolute coordinates?
The coordinates measured by the Phantom 4 RTK are absolute coordinates under WGS84.
How do I calculate an appropriate flight altitude based on a GSD value?
You can refer to the equation H=36*GSD to estimate an appropriate flight altitude. Please note that GSD ground sampling distance in this equation is measured by centimeters, while H (Height or flight altitude) is measured by meters. For example, GSD=2.74 cm, when altitude=100 m.
Do images captured by the Phantom 4 RTK store altitude any information? If so, how is this data stored?
Elevation and relative altitude (relative to your takeoff point) are stored in photos captured by the Phantom 4 RTK. Absolute altitude can be used for mapping, and relative altitude can be found in the XMP file.
How can I capture oblique photography when using the Phantom 4 RTK?
Oblique imagery can be captured while flying in the Photogrammetry mode on the GS RTK app. In the Photogrammetry mode, you can adjust gimbal angle from -90 °to -45° under Camera Settings for your flight plan.You can only set one gimbal angle value at a time, so for sites where you want to capture multiple angles you can plan the same mission and just adjust the camera angle.
Can I create a 3D model or point cloud with third-party software using the images captured by the Phantom 4 RTK? If yes, what is the accuracy of the model created?
Yes, you can use third-party software to process Phantom 4 RTK image data and create models, however the accuracy will vary based on the photogrammetric algorithm used. Please refer to the third-party software provider for more information on expected accuracy.
When there are no Ground Control Points (GCPs), what is the accuracy of the model that the Phantom 4 RTK data can make? Can the accuracy meet the requirements of 1:500 scale aerial triangulation?
The orthoimages created with the images captured by the Phanton 4 RTK and select reconstruction software have shown an absolute accuracy of roughly 5 cm, while the accuracy required in 1:500 scale aerial triangulation is less than 30 cm.

Is the Phantom 4 RTK compatible with third-party base stations?
No, you cannot connect third-party base stations to the Phantom 4 RTK or the remote controller via a radio station. However, you can obtain data from a network RTK server via Ntrip protocol in 4G/Wi-Fi network environment. Satellite observation data can also be saved in the aircraft for users to conduct post processed kinematics (PPK) to complete their tasks.
