Overview
Tethered quad-rotor surveillance UAV with free-flight mode
A tethered quad-rotor surveillance drone that stays aloft for 12 hours or more on ground power, sends control and video over a fibre-optic tether with no radio, and can release the tether for a free flight of 35 minutes or more.
The aircraft climbs to 120 m or more on a 150 m tether that carries 3 kW of power and a fibre-optic data link, while a motorised winch pays the tether out and reels it in automatically. When the mission moves, the operator releases the tether in the air and the drone flies on by itself.
