2.3.4 Beam Divergence Angle
A divergence angle, if any, of the beams from the LiDAR can produce light spots which increase in
size as the distance increases.
2.3.5 Ranging Accuracy
Ranging accuracy refers to the discrepancy between the LiDAR-measured distance and the actual
distance. Ranging accuracy is different from system accuracy in that the former does not represent
the accuracy of the final result.
3. DJI L1 Field Operation Guide
3.1 RTK/PPK
For the purpose of point cloud data processing, L1 needs to have centimeter-accurate positioning
data with either RTK or PPK. The RTK FIX status needs to be maintained throughout the duration of
the L1 flight mission. If RTK connection stability cannot be guaranteed, PPK could also be used. The
detailed workflows of each method are described below.
3.1.1 Ntrip (Custom Network RTK) Solution
In the RTK settings page of the DJI Pilot App, you can choose Custom Network RTK, and enter the
NTRIP account information to connect to the Ntrip service. (Note: The remote controller must be
