Developed for the U.S. Navy by Lockheed Martin, the Mobile User Objective System (MUOS) is revolutionizing secure ultra-high frequency (UHF) satellite communications (SATCOM) for mobile forces.

MUOS radio terminal users -- supporting mobile, tactical ground, sea or air operations -- can seamlessly connect around the globe and into the Global Information Grid, as well as into the Defense Switching Network. MUOS’ new capabilities include simultaneous crystal-clear voice, and video and mission data on a high-speed Internet Protocol-based system.

Delivering the next generation of narrowband communications, each MUOS satellite has two payloads supporting both these new Wideband Code Division Multiple Access (WCDMA) waveform capabilities and the legacy UHF satellite communications system, still used by many mobile forces today. Once operational, MUOS will provide 16 times the capacity of the legacy system it will eventually replace.

The MUOS network is sustained by an initial configuration of four orbiting satellites (MUOS 1-4) and four relay ground stations. An on-orbit spare, MUOS-5, will ensure the network is always available to support U.S. and allied mobile forces, as well as actively supporting the legacy UHF system.
