The Mobile User Objective System, or MUOS, is a constellation of geostationary communications satellites operated by the US Navy. Consisting of five spacecraft – MUOS is a replacement for the earlier UHF Follow-On (UFO) programme and will provide video, voice and data communications to mobile terminals with near-global coverage.

The satellites provide two services, a legacy UHF communications system to provide continuity for users of the UFO satellites and a new, more advanced service: Wideband Code Division Multiple Access (WCDMA).

MUOS’ WCDMA capabilities only require four of the five satellites, so in this role MUOS-5 will serve as a reserve satellite; however its UHF payload will be fully operational.
