[0062] UAV take-off: The secondary control personnel control the tethered UAV to be powered on, and the UAV automatically matches the ground station. The main control personnel send remote control instructions to control the autonomous take-off of the tethered UAV, and the cable winding and unwinding device 10 automatically pays out the cable. The tethered UAV flies to a predetermined height of 200m - 300m with the RRU and omnidirectional antenna and starts to provide public network communication signals.

[0063] UAV landing: The main control personnel send instructions to control the autonomous landing of the tethered UAV, and the cable winding and unwinding device 10 automatically winds up the cable.

[0064] UAV return: After the tethered UAV lands on the lifting platform 2, the secondary control personnel control the UAV to power off.
