Abstract
A UAV system includes a remote controller including two first antennas and a UAV including two second antennas arranged at two landing stands of the UAV, respectively. The two first antennas and the two second antennas are configured to establish a 2×2 MIMO communication link. The remote controller is configured to transmit current terminal position information of the remote controller to the UAV via the 2×2 MIMO communication link. The UAV determines current remote controller relative position information of the remote controller relative to the UAV according to the current terminal position information and current UAV position information acquired via a position sensor, and controls communication between the UAV and the remote controller according to the current remote controller relative position information.
