The invention discloses an unmanned aerial vehicle, positioning equipment and a positioning system. The unmanned aerial vehicle is characterized in that a controller sends a first ultra wide band (UWB) signal to a radio frequency transceiver circuit; the radio frequency transceiver circuit transmits a first UWB signal through the antenna array, receives a feedback UWB signal for the first UWB signal from a positioning device of the parking apron through the antenna array, and sends the feedback UWB signal to the controller; the controller obtains the distance between the unmanned aerial vehicle and a positioning device of the parking apron according to the transmission time of the first UWB signal and the transmission time of the feedback UWB signal; the antenna array comprises a plurality of antennas, and the plurality of antennas form a plane; the controller obtains the angle between the unmanned aerial vehicle and the positioning equipment of the parking apron according to second UWB signals sent by the positioning equipment of the parking apron and received by the multiple antennas; according to the distance and angle between the unmanned aerial vehicle and the positioning equipment of the parking apron, the unmanned aerial vehicle is controlled to return, and automatic and accurate return of the unmanned aerial vehicle can be realized.

    本申请公开了一种无人机、定位设备及定位系统,无人机包括:控制器向射频收发电路发送第一超宽带UWB信号;射频收发电路通过天线阵列发射第一UWB信号,并通过天线阵列接收来自停机坪的定位设备针对第一UWB信号的反馈UWB信号,并将反馈UWB信号发送给控制器;控制器根据第一UWB信号的传输时间和反馈UWB信号的传输时间获得无人机与停机坪的定位设备之间的距离;天线阵列包括多个天线,多个天线形成一个平面;控制器根据多个天线接收的停机坪的定位设备发送的第二UWB信号获得无人机与停机坪的定位设备之间的角度;根据无人机与停机坪的定位设备之间的距离和角度控制无人机返航停机坪,能够实现无人机的自动精准返航。
