Navy accepts MUOS-2

SUNNYVALE, Calif. -- Lockheed Martin has completed on-orbit testing of the second Mobile User Objective System (MUOS) satellite and handed over spacecraft operations to the U.S. Navy. The handover also includes acceptance of three MUOS ground stations that will relay voice and high-speed data signals for mobile users worldwide. MUOS-2 was launched July 19, 2013 aboard a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station, Fla. The system improves secure communications, delivering simultaneous and prioritized voice, video and data for the first time to users on the move.
