US Navy launches MUOS-3 satellite
The US Navy and Lockheed Martin launched the third Mobile User Objective System (MUOS) satellite, MUOS-3, the company announced on 20 January.
MUOS operates like a smart phone network in the sky, vastly improving current secure mobile satellite communications for warfighters on the move. Unlike previous systems, MUOS provides users an on-demand, beyond-line-of-sight capability to transmit and receive high-quality, prioritised voice and mission data, on a high-speed Internet Protocol-based system.
Replacing the legacy Ultra High Frequency (UHF) follow-on system, MUOS satellites have two payloads to ensure access to UHF narrowband communications as well as new capabilities. MUOS’ advanced Wideband Code Division Multiple Access (WCDMA) payload incorporates commercial technology and a new waveform to provide users priority-based capacity.
Once fully operational, MUOS will provide 16 times the capacity of the legacy system. More than 50,000 terminals that are in the field today can be retro-fitted with WCDMA.
