3.1.1.1.2. Physical Base Station Solution (D-RTK 2)
Set up D-RTK 2 at a point with known coordinates and keep the measuring rod touching the ground.
This solution requires that the base station is set up stably and protected properly. If tilt or
displacement exists, calculations cannot be performed properly.
On the settings screen of Matrice 300 RTK or Matrice 350 RTK, select D-RTK 2 and change its
status to Mode 5. Then, link the aircraft to D-RTK 2 by entering the password, which is 123456 by
default. Go to the Advanced Settings screen in the app and change D-RTK 2's coordinates to those
of the known point. (In elevation scenarios, add the device height of 1.8 meters to the elevation of
the known point on the ground.)

After setting up the D-RTK 2 base station, you can connect to D-RTK to fly the aircraft.
Alternatively, you can set RTK to None in the RTK settings of the remote controller to switch to the
GNSS flight mode. After the data collection for the task is done, use a Type-C cable to connect the
aircraft to D-RTK 2. Copy the base station file with a suffix of .DAT for the corresponding time slot,
and paste the file into the same folder as the raw point cloud data. DJI Terra can then calculate the
difference automatically during data post-processing.
Note: If you need higher absolute accuracy or need to change the setup point of the D-RTK 2 base
station, set up D-RTK 2 at a known point instead of directly using its self-convergent GNSS
coordinates. This is because the statically convergent coordinates of D-RTK 2 have meter-level
errors and the error direction is unknown. If the data is used directly, the absolute accuracy of the
result cannot be guaranteed and the data of multiple flights cannot be spliced together.
3.1.1.1.3. Physical Base Station Solution (Third-Party RTK Device)
When no network RTK is available and D-RTK 2 Mobile Station is unavailable, a third-party RTK
base station device can be set up at a known point in the mapping area. In this case, no
connections are required between the aircraft and the RTK base station. After the flight is
