UMAR - UNMANNED MULTIROTOR AERIAL RELAY
Large Tethered UAS for Vehicles, Boats and Ships
The Unmanned Multirotor Aerial Relay (UMAR) is a tethered drone that lifts payloads, such as communication antennas up to 500+ ft. with 400+ hr. endurance. Just by lifting up an antenna, the UMAR system can extend boat/ship radio line of site from 8 miles to 30 miles!
Use Cases
- Maritime Broadband Communication
- Emergency portable cell phone tower
- Port/stadium security
- Traffic monitoring
- Air quality monitoring
- Radio range extension of unmanned boats and ground vehicles
- Telecommunications
- Long endurance environmental assessments & surveys
