Broadcast Mode

How does the D-RTK 3 Multifunctional Station connect to an aircraft in Broadcast Mode? Will I need to manually reconnect it for the next use?

Access the RTK settings page on your aircraft and select "D-RTK Base Station" as the RTK source. Then, choose the desired D-RTK device from the scanned list to connect. For future uses, the aircraft and remote controller will automatically connect once powered on. If the connection is not established automatically, you can manually trigger it in the settings.

How do I set coordinate points in Broadcast Mode for the D-RTK 3 Multifunctional Station?

You can set coordinate points by accessing the Coordinate Calibration section within the RTK settings. The base station's coordinate points can be established through Network RTK calibration, PPP calibration, or manual calibration.

What should I do if I forget the administrator password for D-RTK 3 Multifunctional Station in Broadcast Mode?

Press and hold the power button for 10 seconds to reset to the default password "123456".

Can the station be moved when using the D-RTK 3 Multifunctional Station as a Base Station?

No, the D-RTK 3 Multifunctional Station will monitor its current position for any movement. If movement is detected, a displacement warning will appear in the app, and the flight mission will be terminated, requiring the user to return and manually land the drone. The system will only resume normal operation once the D-RTK 3 Multifunctional Station updates its position.

How should the D-RTK 3 Multifunctional Station be set up as a Base Station, and what precautions should be taken?

Set it up in an open, unobstructed area where the antenna can effectively cover the measurement and takeoff areas. When using the survey pole for installation and elevation, be mindful of the surrounding environment to prevent toppling or electrical hazards.

When are the D-RTK 3 Multifunctional Station satellite raw observation files generated, and how can they be exported?

A satellite raw observation file is generated each time the device is powered on and off in Relay Station Mode or Broadcast Mode. To export the files, connect the device to a computer, and copy the DAT files corresponding to the task timing from the removable disk that appears. These files can then be processed using DJI Terra.

Rover Station Mode

How do I connect the D-RTK 3 Multifunctional Station in Rover Station Mode to a network RTK signal?

In the DJI Enterprise app settings, enter the NTRIP configuration information provided by your network RTK service provider to connect to the network RTK.

How can I export the control point data in Rover Station Mode of the D-RTK 3 Multifunctional Station?

In the DJI Enterprise app, select the "Mission Library," then choose "Export" to export control points compatible with DJI Terra in JSON format and control point results in CSV format.

How do I use the Tilt Compensation feature on the D-RTK 3 Multifunctional Station?

In the DJI Enterprise app, tap the Tilt Compensation icon and follow the app instructions to complete the shaking and inertial navigation calibration to enable Tilt Compensation.

How is the base station height calculated in Rover Station Mode for the D-RTK 3 Multifunctional Station?

The DJI Enterprise app has built-in parameters for this purpose. You only need to enter the pole height directly when using the app. If you are using a third-party surveying pole without a pole height marker, the pole height is calculated from the bottom tip of the pole to the nut joint after the pole is screwed into the main unit (excluding the part screwed into the nut).

How is the base station height calculated in Rover Station Mode for the D-RTK 3 Multifunctional Station?

Input the survey rod height in the DJI Enterprise app, and the app will automatically calcuate the central height.

How is the Tilt Compensation feature implemented in Rover Station mode of the D-RTK 3 Multifunctional Station? What scenarios does it support?

The Tilt Compensation feature is implemented using the device's built-in IMU sensors, which determine the current tilt angle of the device. The actual position of the pole's pointing is determined through trigonometric calculations. This feature supports marking points in locations such as corners of walls, roadsides, and utility poles, where upright point marking is difficult or inconvenient, allowing for tilted point marking.

Will not installing the OcuSync Orientation Antennas affect the Rover Station when measuring control points with the D-RTK 3 Multifunctional Station?

You can operate the Rover Station without the OcuSync Orientation Antennas installed. However, prolonged removal may compromise the waterproof integrity of the antenna interfaces. Therefore, it is advisable to remove them only if absolutely necessary.

What data format does the D-RTK 3 Multifunctional Station generate in Rover Station mode? How can it be imported into DJI Terra with one click?

The control point and checkpoint data exported from the DJI Enterprise app are in JSON format. When using DJI Terra's ground control point management feature, you can import this data as control points and checkpoints with a single click, without needing to select a format.

Relay Station Mode

How does the D-RTK 3 Multifunctional Station connect to an aircraft in Relay Station Mode?

1. Turn on the remote controller and aircraft, and ensure they have completed pairing. On the home screen of the DJI Pilot 2 app, tap the relay pairing button, and select "Connect Relay Device" to enter pairing mode.
2. Press and hold the power button on the D-RTK 3 Multifunctional Station for 5 seconds to enter the linking mode, during which the mode indicator will flash.
3. After Once the D-RTK 3 Multifunctional Station links with the remote controller and the aircraft, the mode indicator will display a solid blue light.

What should I pay attention to when using the D-RTK 3 Multifunctional Station in Relay Station Mode?

To ensure good image transmission relay performance, please set up the D-RTK 3 Multifunctional Station at a high location, such as on a rooftop, whenever possible. If you want to use the relay RTK function, the D-RTK 3 Multifunctional Station must be fixed in place, and its top needs to be unobstructed.

In which countries or regions is the D-RTK 3 Multifunctional Station Relay Station Mode not supported?

Relay Station Mode is unavailable in countries or regions without 5GHz frequency support, such as Japan, Russia, and Kazakhstan. Only the Base Station and Rover Station modes are supported in the aformentioned countries. In Relay Station Mode, if a previously paired drone remote controller and relay station are brought to Japan for use, the remote controller and drone will not be able to connect with the relay station. Additionally, if you attempt to pair the remote controller with the relay station in Japan, the pairing will fail.

How can a paired remote controller be reconnected to a new drone while in Relay Station Mode on the D-RTK 3 Multifunctional Station?

1. Pair a new aircraft while the relay station is powered on.
2. If the relay station is powered on after pairing the new drone, you can restart the drone or the remote controller, and then pair it with the relay station again to establish a connection among all three devices.

How do I activate the D-RTK 3 Multifunctional Station?

Frequency pairing is only required in Relay Station Mode. In Relay Station Mode, select the relay station pairing option on the remote controller, then press and hold the D-RTK 3 Multifunctional Station power button for 5 seconds to enter pairing mode.

What is the connection logic for the D-RTK 3 Multifunctional Station in Relay Station Mode?

In Relay Station Mode, the station connects simultaneously to both the remote controller and the aircraft, while the remote controller also maintains a signal connection with the aircraft. The aircraft will switch its signal connection method during flight based on the actual flight environment. The remote controller's flight interface will only display the integrated signal.

What are the practical applications of the D-RTK 3 Multifunctional Station in Relay Station Mode?

Relay Station Mode can be used when obstructions in the aircraft's takeoff area affect communication between the aircraft and the remote controller. Placing the Relay Station at a high point in an area can bypass obstructions, extending the signal control range. The Relay Station can be set up in unfavorable on-site environments, allowing the pilot to operate the remote controller from a shaded location, indoors, or inside a vehicle.
