MUOS satellite tested

The first Mobile User Objective System (MUOS) military communications satellite built by Lockheed Martin for the U.S. Navy has successfully completed a major end-to-end system test, validating satellite performance and functionality with user ground terminals. Completion of this key milestone confirms the system meets requirements and allows the satellite to proceed to final factory test activities prior to launch. MUOS will augment and replace the Ultra High Frequency (UHF) Follow-On system (UFO) providing communications, including simultaneous voice, video and data, for mobile warfighters.
