Mission Description: The Navy’s Mobile User Objective System (MUOS) is a next-generation narrowband tactical satellite communications system designed using a combination of orbiting satellites and relay ground stations to significantly improve communications for U.S. forces on the move. MUOS will provide new beyond-line-of-sight secure communications capabilities, with smartphone-like simultaneous voice, video and data – to connect military users almost anywhere around the globe.
