The Phantom 4 RTK has a similar shape and size. As well as an RTK positioning module, the new TimeSync system and a mapping application, among other things.

Which propellers does the Phantom 4 RTK use?

The Phantom 4 RTK uses the same 9455S 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 country and/or region specific versions. Users can check their version code on the product packaging or in the GS RTK application (go to Aircraft Information – Firmware).

CAMERA
Frequently Asked Questions about Camera

How does the Phantom 4 RTK camera differ from the Phantom 4 Advanced/Pro camera?

While the Phantom 4 RTK and Phantom 4 Pro/Advanced share the same one-inch, 20-megapixel CMOS sensor, the Phantom 4 RTK’s camera has gone through a process of measuring and recording lens distortion in order to be used for mapping work. All Phantom 4 RTK cameras go through a calibration process in which lens distortion is measured and recorded in parameters. The camera allows users to take images without distortion correction, along with the distortion correction parameters in an XMP file for post-processing.

Can the ND filters of the Phantom 4 Pro be used with the Phantom 4 RTK?

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

Can the Phantom 4 RTK camera’s digital signal processor correct distortions?

No, you can enable distortion correction in-camera, but the images will be less accurate than those that can be obtained by removing distortion in post-processing.

How is the Phantom 4 RTK camera calibrated?

All Phantom 4 RTK cameras go through a calibration process in which lens distortion is measured and recorded in XMP DewarpData parameters. When “distortion correction” is disabled, the original image will be saved with the distortions. When “distortion correction” is activated, distortion is removed using the factory settings, not the calibrated ones. Distortion correction is not performed pixel by pixel.

No.

VIDEO TRANSMISSION
Frequently Asked Questions about Video Transmission

What is the video transmission range of the Phantom 4 RTK?

The effective video transmission range depends on your working configuration (e.g. antenna position) and flight environment. In an open, unobstructed area, the maximum range is 7 km according to FCC standards and 5 km according to CE standards. (2.4 GHz).

What should I do if the application sends me the following notification: “the remote controller signal is weak, please adjust the antenna”?

This means that incorrect antenna placement will affect the video transmission and the quality of the real-time view. You can adjust the antennas so that the flat side of the antenna faces the Phantom 4 RTK.

Can I continue my automated mapping task if the Phantom 4 RTK loses the video signal during the task?

Yes, if the video signal is lost you can reconnect and resume the task.

BATTERY
Frequently Asked Questions about Batteries

Can I use the batteries from my Phantom 4 Pro with the Phantom 4 RTK and vice versa?

Yes, the Phantom 4 RTK and Phantom 4 Pro have compatible batteries, with the same capacity. This means that flight time will not be affected.

How long does it take to fully charge a Phantom 4 RTK battery?

It takes about 60 minutes to fully charge the Phantom 4 RTK battery.

How should I maintain and store the batteries?

Batteries should be stored in a dry, cool and well-ventilated place, away from possible fires, high temperatures or flammable materials. Do not place the battery in an environment that may cause the battery temperature to rise, such as in direct sunlight or inside a car exposed to the sun. For long-term storage, make sure that the charge level is above 50 %, but not fully charged. The battery should be charged and discharged every three months to keep it active if it is stored for a long time.

What does it mean when the battery icon turns yellow in the application?

This means that the battery is low on charge. Be careful when flying in this situation.

Can I use the Phantom 4 RTK batteries at low temperatures?

Battery capacity and, therefore, flight time will drop dramatically at low temperatures. (<-10 °C/14 °F). It is recommended that you warm the batteries to 20 °C/68 °F before take-off to lessen this effect. To ensure flight safety, the battery cannot be charged if the temperature is below 5 °C/41 °F or above 40 °C/ 104 °F.

Why do batteries start to heat up after being stored for a long time?

This phenomenon is normal. When batteries are stored for a long time with more than 65% charge remaining, an automatic discharge process will be initiated to reduce the battery to 65%. This will cause the battery to heat up.

POSITION AND ORIENTATION
Frequently Asked Questions about Positioning and Orientation

What options do I have for referencing Phantom 4 RTK positioning data?

  1. Connect through OcuSync to your D-RTK 2 Mobile Station. (RTCM3.2)
  2. Remotely connect to a custom RTK network with a 4G accessory using an NTRIP account. (RTCM3.2)
  3. Connect remotely via Wi-Fi to a customized RTK network with an 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 capture data with an accuracy of 1 cm + 1 ppm (horizontal) and 1.5 cm + 1 ppm (vertical).

What is TimeSync and how does it ensure the positioning accuracy of each image taken with the Phantom 4 RTK?

TimeSync continuously synchronizes the flight controller, camera and RTK module, and adjusts the positioning data to the CMOS center, saving the data in EXIF and XMP format.

What is the difference between PPK and RTK modes, how are they used?

RTK and PPK are two different kinematic technologies and reference data in different ways. Although PPK is generally slightly more accurate than RTK, both achieve centimeter-level accuracy. RTK is recommended for users who will be flying in environments with real-time connection via OcuSync or 4G and who prefer practicality and efficiency. For users who have enough time and do not mind operating offline, PPK is a better option.

What PPK file types does the Phantom 4 RTK support, what are these files for and how do I use them?

EVENTLOG.bin is a binary file containing the logs, time data and information about the exposure.

PPKRAW.bin is a file in RTCM3.2 MSM5 format containing satellite information and ephemeris data.

Rinex.obs is a file in RINEX format created after encoding.

Timestamps.MRK is a file in ASCII format containing exposure information and temporal data.

How do I find the XMP information in the photos taken with my Phantom 4 RTK?

Open the photo in text format and search for “XMP” to find this information in each photo.

Cuando saco una foto con el Phantom 4 RTK, ¿cuál es el punto de referencia de la información de posicionamiento?

Thanks to the new TimeSync system, each photo stores the position of the CMOS center in the metadata.

Where can I find the offset value between the phase center of the antenna and the center of the CMOS sensor?

For each photo the offset level between the phase center of the RTK module antenna and the CMOS sensor is stored in the time stamp in the NED coordinate system, in a .MRK file in the “survey” folder.

What calculation method does the PPK cloud service use?

Kinematic post-processing can be performed with the PPK cloud service in two different ways: With the DJI Base Station and with a RINEX Base Station.

(1) DJI Base Station: Connect the DJI D-RTK 2 High Accuracy GNSS Mobile Station to the remote control with a USB cable to upload the PPK data to the base station. Once the server has the aircraft and D-RTK 2 information, it will automatically start the PPK calculations.

(2) RINEX base station: Converts satellite information received from third party base stations to the RINEX standard format. Then, import the PPK information to the remote control and upload it to the cloud for PPK calculations.

In which folder on the SD card should I save third party satellite data for kinematic post-processing calculations with a RINEX base station, where will the calculation results be saved?

You should save the third party satellite data in the folder \third_base, and place it in the root directory of the remote control’s SD card. The post-processing results will be saved in (root directory)\DCIMSURVEY(mission name)\result.csv.

¿Cómo puede conseguir el servicio PPK en nube de coordenadas de las estaciones base de terceros si estoy utilizando una estación base RINEX para realizar los cálculos PPK?

(1) If the RINEX file contains an “APPROX POSITION XYZ” field, which includes the approximate location of the base station in the ECEF coordinate system, the cloud PPK service will be able to compare it with the information collected in the field and convert it to geographic coordinates. These coordinates will be set by default as the phase center of the base station antenna.

(2) Users can manually enter the longitude and latitude information of the base station, as well as the distance between the lowest part of the base station and the antenna phase center (APC). With this information, the PPK cloud service will perform calculations based on the user’s manually entered antenna phase center.

(3) The cloud PPK service can also get the location of the antenna phase center through single point positioning (SPP) with RINEX information. These coordinates will be used for PPK calculations. *

*Available only in Europe at this time.

Where is the PPK cloud service available?

The service is available in all countries except the USA, Canada, Hong Kong and Macau.

Where are the coordinate files saved when I use the D-RTK 2 mobile station as an RTK scanner?

You can find it at Download.

How does the RTK scanner perform the measurements?

There are two ways:

(1) Instantaneous measurement

(2) Average of 10 values measured over a period of 2 seconds.

Does the D-RTK 2 Mobile Station need to have the RTK set to “FIX” to be used as a scanner?

(1) If you want to perform instantaneous measurements, it must be set to “FIX”.

(2) For average measurement, it is recommended that it be set to “FIX”.

How can I update the firmware of the D-RTK 2 Mobile Station?

At this time you can only update it via the Phantom 4 RTK remote control (not the Remote Control SDK).

What is the “RTK positioning accuracy maintenance” mode?

When the RTK positioning accuracy hold mode is enabled, and if signals from the RTK base station are lost, the positioning accuracy will slowly decrease from the absolute accuracy of 1 cm + 1 ppm down to approximately 20 cm. The RTK Flag value in the image XMP data will be 16, and the RTK status of the remote control will remain FIX.

SOFTWARE
Preguntas frecuentes sobre el software

How can I update the Phantom 4 RTK firmware?

Updating the Phantom 4 RTK firmware is similar to updating the Phantom 4 Pro firmware. You can update the remote control and aircraft firmware separately with DJI Assistant 2.

You can also update the drone and the remote control at the same time with the GS RTK application. First you have to connect the remote control to the aircraft with the OTG and USB cables. Then follow the instructions in the GS RTK application on the remote control.

In which situations are the lateral infrared sensors activated?

At this time the infrared sensors are not active, fly with caution.

What software can I use to plan flights and control my Phantom 4 RTK?

You can use the GS RTK application to plan and control flights. For mapping missions you can use the specialized PC software DJI Terra. If you have purchased a Remote Control SDK, you can also use DJI GS Pro, DJI Pilot and other third-party applications that have been developed using DJI’s Mobile SDK.

Which mapping platform is used as the source of the mapping data for the Phantom 4 RTK application?

Mapbox supplies map data to the GS RTK application.

What are the benchmark limitations of the Phantom 4 RTK?

In the GS RTK application the maximum number of reference points is 199. In DJI Terra the reference points can be up to 2 km away, and only a maximum of 99 points can be set. The total distance of a Trajectory mission cannot exceed 40 km, and in Photogrammetry mode the maximum distance is 100 km.

Can I set reference points by typing longitude and latitude values in the Trajectory mode?

No.

When importing KML area files into software programs, what is the maximum number of perimeter points I can set?

The maximum number of perimeter points supported by the GS RTK application is 199. In Terra’s case, it is 99.

In which missions can I import KML files?

In the following missions: 2D Photogrammetry (Photogrammetry 2D), 3D Photogrammetry (Dual Grid) (Photogrammetry 3D wpcodeself),[Double Grid] 3D Photogrammetry (Multiple Orientation) (Photogrammetry 3D wpcodeself[Multi-oriented]), Area Segmentation (Block Segmentation) and Constant Height (Terrain Awareness).

In Terrain Awareness mode, is there any way to disable the display of the terrain redrawing map?

Yes. Click on the — icon in the upper right corner during this mode, then click on the — icon in the sidebar. You will reach the general settings, where you can disable this display.

When is it advisable to use Block Segmentation?

Area segmentation divides large areas of territory into several flight paths to improve mission efficiency. It offers the best results when flying over relatively flat areas without major elevation changes.

How do I use area segmentation to plan flight missions?

(1) Select area segmentation (2) Set the area to be mapped: you can do this manually or import kml files

(3) Adjusts grid dimensions and direction (4) Adjusts camera settings and overlap ratio.

In area segmentation, are flights planned separately for each section, or are they planned as a whole?

Flight routes are planned jointly. It is not possible to adjust the overlap ratio, altitude, direction or other parameters for each section separately.

How do I control several aircraft at the same time during area segmentation missions?

Cuando termines la planificación, vincula cada Phantom 4 RTK con cada misión de vuelo correspondiente. You can then start one of the missions separately, or all of them at once.

How many Phantom 4 RTK can I control at a time with area segmentation?

A maximum of 5.

If I work with several aircraft at the same time, can I collide with each other?

No. Thanks to obstacle detection technology, when two or more Phantom 4 RTKs approach each other, they will decelerate or hover. They will only continue their mission when the area has been cleared.

Can I run a Phantom 4 RTK mission using altitude above sea level?

Yes, but only in Trajectory.

How do I use the altitude above sea level to fly with the Phantom 4 RTK?

(1) Access the RTK configuration and check that the RTK status is FIX.

(2) Select Trajectory and add reference points with RTK enabled. The system will automatically record the altitude with respect to sea level of each reference point.

(3) Select Absolute Altitude in the altitude pop-up window when performing the operation.

Can I use the altitude above sea level in a mission if I do not have RTK enabled or if its status is not FIX?

No. In such cases you can only use the default altitude.

How much do I have to adjust the Relative Height?

When there is a difference between the altitude of the take-off point and that of the area to be mapped, you can adjust the Relative Height to ensure sufficient overlap ratios in the measurement. See the illustration below for more information:

If the drone takes off from a 50 m building (H1 in the illustration), is going to map area A and the altitude at which it takes aerial images is expected to be 100 m, you can set the mission altitude to 100 m, and the relative altitude to 50 m. Similarly, if the drone takes off from H2 to map area B, which is a 40 m high hill, and the expected altitude for aerial image capture is 60 m, you can set the mission altitude to 60 m and the relative altitude to -40 m. You can adjust the relative altitude (Relative Height) in 2D Photogrammetry, 3D Photogrammetry (Dual Grid) (Photogrammetry 3D) and 3D Photogrammetry (Dual Grid) missions [Double Grid]), 3D Photogrammetry (Multi-Orientation) (Photogrammetry 3D [Multi-oriented]), Linear Flight Mission and Block Segmentation.

In what situations can variable altitude flight path missions be used?

Variable altitude flight paths are useful for taking modeling photographs in terrain with large differences in altitude, such as power transmission lines, roads, and rivers with ascending and descending topography.

Are there altitude and angle restrictions between reference points when planning a variable altitude flight path?

There are no altitude restrictions between two reference points. The actual flight altitude is determined by the altitude limit. There are no angle restrictions.

Does a variable altitude flight path mission support imported KML files? What are the requirements for KML files?

Yes. Click on the “KML” icon in the function menu to select the file. The KML file type must be linear and the format of the field for absolute altitude in the KML file must be “absolute”.

What is “mission altitude” in a variable altitude flight path mission?

It is the distance between the flight plane and the plane between the points A, B and C.

It is the distance between the flight plane and the plane between the points A, B and C.

Yes, a flight path can be executed in reverse sequence. After a flight path has been generated from the recorded landmarks, click the reverse sequence button at the bottom of the interface to reverse the landmark flight sequence.

In what situations can slope flight paths be used?

They are useful for situations involving model elements such as slopes and building facades. Slope flight path planning generates flight paths automatically for sloping surfaces or facades, and correctly collects photogrammetric data.

What is the function of the flight path plan view when executing a slope flight path mission?

During a slope flight path mission, the application interface will display an image transmission window, a map view window and a plan view window. The plan view window is located in the lower right corner of the interface. During a mission, it can display the flight path from a vertical perspective with respect to the aircraft and thus help determine the area to be mapped and position the aircraft.

¿Qué son la “distancia de la misión” y la “altitud de la misión” en una misión de ruta de vuelo en pendiente?

The “mission distance” and “mission altitude” are used to adjust the distance between the flight plane and the plane between points A, B and C. If the slope is steep or completely vertical, you can select the perpendicularity mode with respect to the target plane and adjust the distance between the flight plane and the plane between points A, B and C by setting the “mission distance”. If the slope is relatively flat, you can use the perpendicularity mode with respect to the horizontal plane and adjust the distance between the flight plane and the plane between points A, B and C by setting the “mission altitude”.

How do I ensure flight safety when planning a slope flight path?

When planning the reference points for a flight path over the sloping plane between points A, B and C, pay attention to the area to be mapped taking into account the predetermined expanded distance from point C, and make sure that there are no flight safety risks within the predetermined expanded area.

MAPPING AND MAPPING
Frequently Asked Questions on Cartography and Mapping

What formats does the Phantom 4 RTK support for differential data?

The Phantom 4 RTK currently supports RTCM 3.0, RTCM 3.1, MSM4, MSM5, MSM6 and MSM7 data under RTCM3.2.

Are the coordinates collected by the Phantom 4 RTK relative or absolute?

The coordinates collected by the Phantom 4 RTK are absolute coordinates in WGS84.

How can I calculate the appropriate flight altitude based on a certain ground pixel size?

You can use the equation H = 36.5 × GSD to estimate the appropriate flight altitude. Note that the ground pixel size (GSD) in this equation is measured in centimeters, while the flight altitude (H in the equation) is measured in meters. For example, the GSD is 2.74 cm at 100 m altitude.

Is any real altitude information stored in the photos taken with the Phantom 4 RTK? If so, how is it stored?

The Phantom 4 RTK collects altitude relative to sea level and altitude relative to your takeoff point. The altitude with respect to sea level can be used for mapping, while the relative altitude can be found in the XMP file.

How can I capture a time-lapse photo with the Phantom 4 RTK?

Oblique images can be captured by flying in photogrammetric mode in the GS RTK application. In photogrammetric mode, you can adjust the stabilizer angle from -90° to -45° in Camera Settings according to your flight plan. Only one stabilization angle can be set at a time, so if you want to capture the same location from several angles you will have to plan the same mission with different camera angles.

Can I create a 3D model or point cloud with third-party software from photos taken with the Phantom 4 RTK? If so, how accurate is the model created?

Yes, you can use third-party software to process the Phantom 4 RTK image data and create models. However, accuracy will vary depending on the photogrammetric algorithm used. Consult the software vendor for more information regarding the accuracy to expect.

How accurate are the models generated by the Phantom 4 RTK when no ground control point (GCP) is established, and are the accuracy requirements met for aerial triangulation at 1:500 scale?

Orthoimages created with images captured by the Phantom 4 RTK with specific reconstruction software have shown an absolute accuracy of approximately 5 cm, when the accuracy required for aerial triangulation at 1:500 scale is less than 30 cm. This means that the accuracy of the Phantom 4 RTK meets the requirements for aerial mapping at 1:500 scale.

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 remote control via a radio station. However, you can get the data from an RTK server on a Wi-Fi or 4G network with the NTRIP protocol. Users can store satellite data in the aircraft to perform kinematic post-processing (PPK) to complete their tasks.

If inaccuracies in elevation information occur when collecting orthoimages with the Phantom 4 RTK, what could be the cause?

The causes may be, among others:

(1) Ground control points (GCP) are set in a different coordinate system or with a vertical datum that does not correspond to the position of the Phantom 4 RTK. Make sure that the coordinate systems match.

(2) The RTK status of the Phantom 4 RTK is not FIX. Asegúrese de que el estado de RTK es FIX antes de iniciar la recogida de datos.

(3) The internal camera parameters used during post-processing are not accurate.

If the internal camera parameters used by the post-processing modeling software are inaccurate, resulting in inaccurate altitude, how can altitude accuracy be improved when collecting orthophotographic data using a Phantom 4 RTK?

The “Altitude Optimization” is already configured by default in the parameter settings for the planning modes “2D Photogrammetry” and “Area Segmentation”. After enabling this feature, the Phantom 4 RTK will return to the center of the mapped area after completing the flight path, and gather images of the slope features to improve altitude accuracy. This function is only applicable to the planning modes “2D Photogrammetry” and “Area Segmentation”.
