Abstract:

The Mobile User Objective System MUOS is a narrowband Military Satellite Communications MILSATCOM system that supports a worldwide, multi-Service population of mobile and fixed-site terminal users in the Ultra High Frequency UHF band, providing increased communications capabilities to smaller terminal users while still supporting interoperability to legacy terminals. MUOS adapts a commercial third generation Wideband Code Division Multiple Access WCDMA cellular phone network architecture and combines it with geosynchronous satellites in place of cell towers to provide a new and more capable UHF MILSATCOM system. The constellation of four operational satellites and ground network control will provide greater than ten times the system capacity of the current UHF Follow-On UFO constellation. MUOS includes the satellite constellation, a ground control and network management system, and a new waveform for user terminals. The space segment is comprised of a constellation of four geosynchronous satellites, plus one onorbit spare. The ground system includes the ground transport, network management, satellite control, and associated infrastructure to both fly the satellites and manage the users communications. MUOS is designed to support users that require greater mobility, higher data rates, and improved operational availability. The new waveform is termed the MUOS Common Air Interface CAI, a Software Communications Architecture compliant modulation technique for the Joint Tactical Radio System terminals.
