The communications satellite was launched on Friday, February 24 from Cape Canaveral Air Force Station, Florida at 5:15 p.m. EST. MUOS, the Mobile User Objective System, is a next-generation narrowband tactical satellite communications system designed to improve ground communications for U.S. military forces on the move. It will provide users 10 times more communications capacity over existing systems, including simultaneous voice, video, and data by leveraging 3G technologies. Data rates of up to 384 kbps “on the move” will be available, with MUOS incorporating IPv4 and IPv6 to enable roaming to IP networks. Lockheed Martin (News - Alert) has the contract for building MUOS, which is designed to replace the legacy Ultra High Frequency Follow-On (UFO) system. A total of four MUOS satellites will be put into geosynchronous earth orbit (GEO), along with an on-orbit spare. Each satellite is built using Lockheed’s A2100 bus and is equipped to deliver 16 WCDMA beams. The satellites carry both MUOS WCDMA and legacy UHF SATCOM payloads in order to support both legacy UHF SATCOM terminals and JTRS-compatible terminals... Read More |
