MUOS secure communications satellite system ready for full operational use
DENVER, Colo., – A new global, military, satellite-based cellular network designed for secure communications for mobile forces is now ready for full operational use in warfighting environments.
The Mobile User Objective System (MUOS), developed by prime contractor Lockheed Martin with ground systems provider General Dynamics Mission Systems, was deemed operationally effective, operationally suitable, and cyber survivable, following successful completion of its Multiservice Operational Test and Evaluation (MOT&E). This summer’s rigorous MOT&E, conducted by the U.S. Navy’s Commander, Operational Test and Evaluation Force, included participation from the U.S. Army and the U.S. Marine Corps.
Mobile forces have been conducting early testing and training on MUOS since the network was approved for Early Combatant Command use in July 2016. In August 2018, U.S. Strategic Command approved MUOS for expanded operational use to include non-combat operations – like humanitarian response, disaster relief and further training. The successful MOT&E now makes MUOS’ advanced communications capabilities fully available to the tactical warfare environment.
Comprised of five geosynchronous satellites and four geographically dispersed relay ground stations, the MUOS network brings to mobile forces new, simultaneous, crystal-clear voice, video and mission data over a secure high-speed Internet Protocol-based system. Users with new MUOS terminals will be able to seamlessly connect beyond line-of-sight around the world and into the Global Information Grid, as well as into the Defense Switched Network. MUOS also has demonstrated successful communication of Integrated Broadcast Service (IBS) messages.
Today MUOS’ satellites, built by Lockheed Martin, provide both the advanced, new Wideband Code Division Multiple Access (WCDMA) waveform and legacy SATCOM UHF communications signals to support troops as they transition over to the more-versatile cellular network. MUOS’ ground system, built by General Dynamics Mission Systems, has two locations in the United States, one in Australia and one in Europe -- each supporting the system’s global, beyond-line-of-sight, narrowband communications reach.
The Navy's Program Executive Office for Command, Control, Communications, Computers, Intelligence and Space Systems (PEO C4 and Space Systems), and its Communications Satellite Program Office responsible for the MUOS program, are based in San Diego, California.
