The present invention relates to unmanned aerial vehicles. The method includes: when the magnetometer is invalid or encounters strong magnetic interference, assuming that a track angle is equivalent to the head direction, and accelerating the aircraft in a head direction; determining whether a speed obtained after the aircraft is accelerated reaches a preset value; if the speed reaches the preset value, obtaining the track angle of the aircraft according to the speed; obtaining a current location and a home point of the aircraft by using a positioning system that can provide global or local coordinates, to obtain a heading angle of the aircraft; determining whether a difference between the heading angle of the aircraft and the track angle of the aircraft is less than a fixed value.
