Mobile User Objective System (MUOS)

muos_6.8.2010_s460

The Mobile User Objective System (MUOS) is a next-generation narrowband tactical satellite communications system designed to significantly improve ground communications for U.S. forces on the move.

MUOS will provide military users 10 times more communications capability over existing systems, including simultaneous voice, video and data, leveraging 3G mobile communications technology.

MUOS systems will fully support legacy UHF SATCOM terminals and Joint Tactical Radio System terminals, ensuring its users receive the technological advancements needed without a gap during necessary system upgrades. The MUOS constellation will also provide enhanced geolocation capabilities.

Program Specifics:

Lockheed Martin Space Systems, Sunnyvale, Ca., is the prime contractor and systems integrator for the U.S. Navy’s MUOS program. On Sept. 24, 2004, the company was awarded a $2.1 billion contract to build the first two satellites and associated ground control elements for the MUOS system. The U.S. Navy has since exercised the contract option to produce three additional spacecraft, developing four MUOS satellites with one on-orbit spare and the supporting ground systems.

MUOS satellites will be developed at the company's Commercial Space Systems unit in Newtown, Pa.; final assembly and test will occur in Sunnyvale. Lockheed Martin's award-winning A2100 bus, which has achieved over 100 years of on-orbit service, will serve as the MUOS spacecraft platform.
