The Hovermast is a general-purpose intelligence-gathering craft that can carry up to 9 kilograms of equipment like radar systems or sensors. It attaches to a small vehicle like a car or truck by a combination power and data cable, then flies above it while collecting data. The HoverMast, which weighs about 10 kilograms, is supposed to be able to rise to heights of 50 meters in 10 to 15 seconds.
