UMAR is a modular, all-weather tethered UAS providing over-the-horizon communications and ISR support from mobile and maritime platforms.

# DPI UAV Systems UMAR – Unmanned Multirotor Aerial Relay (Tethered UAS)

The UMAR (Unmanned Multirotor Aerial Relay) from DPI UAV Systems is a rugged, tethered UAS built for persistent ISR and over-the-horizon communications in mobile and maritime environments. Designed to operate from ships, trailers, or vehicles in motion, UMAR functions as a mobile mast or airborne tower, delivering elevated sensor and radio payloads with minimal operator input.

Key Features and Capabilities

• All-Weather Maritime Design: Operates in rain, salt spray, snow, high humidity, and wind speeds up to 35 knots, without requiring ship stabilization.

• Automated Deployment: Supports semi-autonomous takeoff, vessel-following, and landing, even on moving platforms at speeds over 20 MPH.

• Persistent Power: Powered continuously via tether using 208 or 440 VAC 3-phase shipboard power, with <12 kW consumption.

• Secure Communications: Features jam-resistant, encrypted fiber-optic data links, ensuring uninterrupted ISR and command relay.

• OTH Communications Extension: Elevates payloads up to 500 ft AGL, extending radio and sensor range by 2–3× beyond line-of-sight.

• Payload Flexibility: Carries up to 15 lb, supporting EO/IR sensors, tactical radios, and directional antennas.

• Compact Deployment: UAV weighs 55 lb (with payload), housed in an 8 × 6.5 × 8 ft container; full system weight ~7,000 lb.

• Emergency Battery Backup: Provides 5 minutes of untethered flight in case of power loss.
