Tethered UAV System KWT-TMOP-100

A solution for countless surveillance missions is the ALLTECH tethered UAV system for Permanent Surveillance. Long-term auto-hover is suited for tethered drone platforms. The KWT-X6L multirotor aircraft, the moored airborne power supply, the smart cable recovery device, and the ground high-power electric energy transmission module make up the captive drone platform. The tethered platform recognizes the long-term stagnation of the rotor drone and resolves the battery capacity issue.
