Lockheed Martin delivers US Navy’s first MUOS satellite and gears up for February 2012 launch from the Cape
Lockheed Martin has delivered the US Navy’s first mobile user objective system (MUOS) satellite to Cape Canaveral Air Force Station, Florida, on December 15, where it will be prepared for a February 16, 2012 lift off-aboard an Atlas V launch vehicle.
The MUOS constellation is a next-generation narrowband tactical satellite communications system that will augment and replace the legacy ultra high frequency follow-on system, providing significantly improved and assured communications for the mobile warfighter.
The MUOS satellite will now undergo post-shipment testing, fuelling, payload fairing encapsulation, and mate atop the Atlas V launch vehicle in preparation for launch.
MUOS consists of four geostationary earth orbit (GEO) satellites with an additional on-orbit spare, and a fibre optic terrestrial network connecting four ground stations around the globe. Each satellite will feature two payloads that enable the system to integrate with the existing architecture while upgrading military users to the new wideband code division multiple access (WCDMA) system. Utilising the latest commercial advances in 3G cell phone and satellite technology, MUOS will provide mobile warfighters point-to-point and netted communications services at enhanced data rates and priority-based access to on-demand voice, video and data transfers.
As the first MUOS satellite prepares for launch, the Lockheed Martin team continues to make significant progress on the subsequent satellites. The second MUOS space vehicle is currently undergoing environmental testing which will validate its performance in a simulated space environment. TheĀ third andĀ fourth MUOS satellites are also steadily progressing.
