What is D-RTK 2 mobile base station?
D-RTK 2 High-Precision GNSS Mobile Station (abbreviated as D-RTK 2 mobile station) is the High-precision satellite signal receiver developed by DJI. Users use D-RTK 2 to help UAS to realize RTK positioning.
How to use D-RTK 2 mobile base station?
Preparation
DJI D-RTK 2 supported UAS such as Phantom 4 RTK, M300 RTK and MG-1P RTK
D-RTK 2 mobile base station
UAV Remote Controller
Unfold the tripod on a horizontal ground, insert the extension rod into the tripod, adjust the D-RTK 2 mobile station to the desired height, tighten the sleeve on the tripod, and then attach the D-RTK 2 body onto the extension rod and tighten the lock nut on the D-RTK 2 body.
Ensure that the bubble of the bubble level on the mount base is located within the black circle (viewed from the top of the bubble level vertically).
Mount the battery into the battery compartment.
Powering the D-RTK 2 Mobile Station on
Press and hold the Power button (in the middle) to power on the D-RTK 2 mobile station (The power indicator blinking solid green indicates that D-RTK 2 is on).
Press and hold the Operating Mode button (on the right) to switch modes based on the UAS (The operating mode indicator blinking green once indicates that D-RTK 2 is in the Mobile Station mode).
Linking
Power on the remote controller. initiate the mobile station linking process to link the RC with the D-RTK2 mobile station via the DJI flight controller mobile app such as DJI Pilot, MG, GS Pro and GSR apps.
For example in the DJI MG app, go to Operation View > ... > RTK to enable RTK function. Select the RTK service type to D-RTK 2 Mobile Station. Then tap Linking at the bottom. The remote controller status indicator will blink blue and a beeping sound from the remote controller will indicate that the remote controller is being linked. Press the Link button on the D-RTK 2 mobile station and the link indicator will blink red and green alternatively, indicating that the mobile station is being linked. The linking is successful when the indicator light on the remote controller becomes solid green. After linking the remote controller with the D-RTK 2 mobile station, tap Link with Aircraft in the pop-up window to link with the aircraft. Then press the Link button on the aircraft to finish linking.
Usage
The RTK icon and the satellite number will be shown on the status bar at the top of the Operation View, when the color changes to white, RTK can be used for aircraft positioning.
If users would like to manually input coordinate information, please wait for the system to search for satellites. When FIX is displayed, go to the bottom of the RTK settings page and tap Advanced Settings, and input GNSS coordinates.
If the D-RTK 2 mobile station is restarted after input coordinates are successfully set, these coordinates will be used only if the difference between the actual coordinates and the set coordinates is less than 5 meters, otherwise, the actual positioning coordinates will be used to ensure accuracy.
Notes:
1. The mobile station should be away from high-power radio sources;
2. Ensure that no large area of water or objects that strongly interfere with the reception of satellite signals surround.
3. Do not change the position and the angle of tripod or the D-RTK 2 mobile station after setup, otherwise, it needs to be re-leveled.
4. Ensure that there is no obstacle above the mobile station.
5. After startup, please wait 2 minutes for D-RTK 2 to automatically obtain position information.
6. The input coordinates will be used only if the difference between the actual coordinates and the set coordinates is less than 5 meters..
