Check the following if the RTH isn't working as expected:
- There may be a problem with the Global Navigation Satellite System (GNSS) or a large positioning error. To resolve this issue, make sure that the drone is not in an environment close to buildings, transmission towers, the ground, or a water surface, etc.
- The downward-facing stereo camera may have recorded the scenery of the Home Point, and the drone is trying to return to the point where it actually took off. In this case, there is sometimes a margin of error between the position coordinates of the Home Point on the Airpeak Flight app screen and the actual Home Point.
- The drone may not be able to approach the Home Point if it is near a geofence.
