Compass

Also known as a magnetometer, the compass is an orientation sensor used by the flight controller to determine the direction to which the model is pointing. It is an indispensable sensor for autonomous navigation in multi-rotor aircraft, but is dispensable in fixed-wing aircraft.

Some GPS modules have an integrated compass, which bypasses the requirement of the flight controller to have its own integrated compass.
