A compass calibration is a process used to compensate for magnetic interference that can affect a UAV's magnetometer, which is used to determine heading. This interference can come from the UAV's own electronics, nearby metal objects, or external magnetic fields. The calibration process involves rotating the UAV in various orientations to allow the flight controller to map and compensate for these interferences. The first step is to select a suitable location. Choose a location that is free from magnetic interference. Avoid areas near metal objects, power lines, or other sources of electromagnetic radiation. An open field or park is generally a good choice. The second step is to initiate calibration mode. Power on the UAV and connect it to the remote controller or ground station. Enter the flight controller's software and select the compass calibration option. This will ....
