An orientation control method for a drone is disclosed. The method comprises steps of receiving wireless signal sent wirelessly from a target device by at least three receivers arranged on the drone,and detecting the phase of the wireless signal respectively received by each of the three receivers with a phase detector of the drone. Next, the current relative orientation of the drone with respectthe target device is calculated through a phase differences of the three phases of the three receivers. The drone is controlled to move to orientate user-designated direction according to the calculated current relative orientation and a directional signal sent wirelessly from a remote control. Thus, the drone is allowed to be able to correctly face the direction indicated by a user.
