Abstract: System and method of wireless communication in UAV systems that uses geolocation-based beamforming. The antenna array on the transmit device is first calibrated to compensate the random phase errors of the antenna. During operation, the geolocations of the UAV and its remote control and the rotational position of the transmit device are used to determine a beamforming direction. A beamforming vector is selected based on the beamforming direction. The beamformer on the transmit device then beam forms the antenna array such that data or other information can be transmitted to the receive device in the beamforming direction.
