Lockheed Martin has delivered a UHF satellite communications system module for the second satellite in the U.S. Navy‘s Mobile User Objective System (MUOS) program, the company announced April 29.  

    The MUOS module, which aims to provide assured communications, including simultaneous voice, video and data, to mobile warfighters, features a wideband code division multiple access payload to provides a 10-fold increase over legacy UHF satcom systems in the number and capacity of satellite links. The module also includes UHF legacy systems designed by Boeing.

    The Lockheed technology will support new mobile satellite terminals that are under development for the Joint Tactical Radio System. The company will complete the final test verification phase on the system module, integrate it with the spacecraft propulsion core module and other space vehicle components, and begin environmental and acceptance testing of the fully integrated space vehicle.

    The first MUOS satellite, along with the associated ground system provided by General Dynamics C4 Systems, is scheduled for on-orbit hand-over to the Navy in 2011.
