Configure the DJI D-RTK2 Base Station

This section covers the configuration of your DJI D-RTK2 Mobile Base Station.

You will need to activate your DJI D-RTK2 base station if using for the first time. Refer to Base Station Activation and Setup     for more information.

Mount the DJI D-RTK2 Base Station to the Tripod

To achieve centimeter-level precision, it is essential to set up the base station over a known location with known coordinates. However, the system can also work without a known location, but the D-RTK2’s global accuracy would be at the meter-level, which is the accuracy provided by standard GPS without RTK corrections.

Refer to the Manually Input Coordinates section for more information on adjusting the base station coordinates.

To mount the base station:

1. Find an open outdoor space and set up the tripod. Make sure it is stable, leveled, and has a clear view of the sky. We recommend that you follow these guidelines for optimal performance and accuracy:

   • Tripod Position and Angle: Once the tripod has been leveled, refrain from changing its position or angle to maintain accuracy. If any adjustments are made, it will require releveling.

   • Clear Line of Sight: To ensure a wide field of vision, confirm that there are no obstructions (such as trees or buildings) at an angle exceeding 15 degrees above the horizontal plane of the DJI D-RTK2 antenna. This prevents GNSS signal absorption or blockage.

   • Distance from Emission Sources: Position the setup location at least 200 meters away from high-power radio emission sources, including TV and microwave stations, and maintain a minimum distance of 50 meters from high-voltage transmission lines. This separation is essential to prevent electromagnetic interference with GNSS signals.

   • Avoiding Water and Signal Interference: Choose a location that is distant from large bodies of water and objects that may strongly interfere with satellite signal reception, thereby minimizing multi-path effects.

2. Connect the DJI D-RTK2 body to the extension rod and install the combination on the tripod.

3. Mount the battery to the base station.

4. Adjust the base station using the gradienter, ensuring the bubble is kept inside the black circle.

Power on the Base Station

Short press, then press and hold the Power button (refer to Figure 1) to turn on the base station. The power indicator should be in solid green. In addition, refer to the following table for the link indicators.

Switch the Base Station to Broadcast Mode

The DJI D-RTK 2 Mobile Station provides different operating modes to use with different products. For the M300/M350, the base station should be operating in Broadcast mode (Operating Mode 5).

1. Press and hold the Operating Mode button (refer to Figure 1) for two seconds. The indicator turns yellow and blinks once indicating the base station is ready to switch modes.

   If no action is taken within 2 seconds, the base station will remain in the current mode.

2. Short press the button to cycle through modes. For broadcast mode, the mode light flashes green 5 times.

Connect the M300/M350 Controller to the D-RTK2 Base Station

Follow these steps to link the remote controller to the broadcast network of the D-RTK2 Mobile Station.

1. Mount the Hovermap to the aircraft then connect the Fischer connector to the payload. Also, ensure that the OSDK cable is secured on the top of the drone.

2. Power on the aircraft first, then the Hovermap, and then the M300/M350 controller.

   Make sure that the D-RTK2 Mobile Station you want to connect to is in Broadcast mode.

3. On the M300/M350 controller, open the DJI Pilot Pro 2 app.

4. Tap Enter Camera View then close the Pre Flight Checks page.

5. Tap the More Settings button (…) on the upper-right of the display.

6. Tap RTK from the menu on the left to display the RTK Settings page.

7. Make sure that the RTK Positioning and Maintain Positioning Accuracy Mode are toggled on.

8. In the field next to Select RTK Service Type, tap the down arrow then select D-RTK2 Mobile Station to search for available base stations.

9. You will get a notification after changing the RTK service type. Tap OK then proceed to restart the aircraft.

10. Scroll down to the Status section then connect to the base station by tapping > to bring up the Select D-RTK2 Mobile Station page.

11. Select the name of the base station to connect to and wait for the blue tick to indicate a successful connection. Go back to the main RTK settings page.

12. Once connected, the Status will change from Not Connected to displaying the name of the connected base station. Check that the Orientation and Positioning status also show as “FIX” to indicate that the RTK module is ready and the aircraft is ready for flight.

Restart the aircraft if you are experiencing connection and configuration issues.

Manually Input Coordinates

It is crucial to have accurate base station coordinates as drone RTK readings are computed relative to the base station location. This can be obtained by setting up the base station over a known surveyed point or manually adjusting the base station coordinates.

To adjust coordinates:

1. Scroll to the bottom of the RTK Settings page.

2. Tap Advanced Settings then enter the administrator password for the D-RTK2 mobile base station (default password is 123456).

3. In the Advanced Settings page, tap Adjust Coordinates.

4. Input the current location information of the mobile station and tap OK to record the location in the system.

If the input values for Broadcast Mode are over 15m away from the actual DJI D-RTK2 Mobile Station coordinates, they will    not be accepted. In case the DJI D-RTK2 Mobile Station is restarted after the input coordinates have been successfully set,   those coordinates will only be used if the difference between the actual and the set coordinates is less than 5m. Otherwise,   the actual positioning coordinates will be used.

You are now ready to perform a scan mission.
