Notes:

1. The accuracy was measured under the following conditions in a DJI laboratory environment: after a 5-minute warm up, using Mapping Mission with Calibration Flight enabled in DJI Pilot, and with the RTK in FIX status. The relative altitude was set to 50 m, flight speed to 10 m/s, gimbal pitch to -90°, and each straight segment of the flight route was less than 1000 m. DJI Terra was used for post-processing.
2. Measured in an environment of 25℃ with a target (80% reflectivity) 100 meters away. The result may vary under different test conditions.
3. The recommended microSD cards may be updated in future. Visit the DJI official website for the latest information.
