The Cobra is a tethered drone that receives power from a ground module via cable, allowing it to stay in the air for many hours continuously. It can carry payloads up to 3kg at 100m altitude or 5kg at 50m altitude, such as a 36x optical zoom camera or retransmitter, and provides reliable communications for ground forces and other unmanned vehicles. Setup and flight are fully automatic, taking off, flying, and landing with only a start confirmation and button press on a touchscreen tablet or phone.
