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.

Abstract: The present disclosure relates to an inertia measurement module for an unmanned aircraft, which comprises a housing assembly, a sensing assembly and a vibration damper. The vibration damper comprises a first vibration-attenuation cushion; and the sensing assembly comprises a first circuit board, a second circuit board and a flexible signal line for connecting the first circuit board and the second circuit board. An inertia sensor is fixed on the second circuit board, and the first circuit board is fixed on the housing assembly. The inertia measurement module further comprises a weight block, and the second circuit board, the weight block, the first vibration-attenuation cushion and the first circuit board are bonded together. The present disclosure greatly reduces the influence of the operational vibration frequency of the unmanned aircraft on the inertia sensor and improves the measurement stability of the inertia sensor.
