UMAR – Unmanned Multirotor Aerial Relay

dp-16-diagram-full“Following” Comm Relay for Boats and Vehicles

With a moving platform below, the six rotor motors are redundant in order to maximize reliability. By overlapping the upper and lower rotors, DPI UAV Systems takes advantage of an additive lift effect and can minimize the rotors’ size. This reduces both the visual and acoustic profile.

The UMAR is a small, intelligent, tethered UAV that flies up to 500 feet above its vehicle (boat, truck, etc.). Unlike other tethered UAVs, the UMAR is intelligent, autonomous and capable of maintaining airspeed.

Land on moving platforms: With advanced object recognition and obstacle avoidance technology, the UMAR can land on pitching, heaving, and rolling platforms, as well as traveling platforms.
