Program: MUOS

Mobile User Objective System

Narrowband tactical satellite communications system to replace UHF

Will cost $2.1 billion. The concept study was provided by Lockheed Martin Missiles & Space for $700,000.
Five satellites are planned, with an option for 3 more.


Lockheed Martin Space Systems, General Dynamics C4 Systems and Boeing Satellite Systems (BSS) are to produce the first two satellites and associated ground control elements.

With Lockheed Martin's design, MUOS satellites will be fully compatible with the existing UHF system and associated legacy terminals while significantly increasing military communications availability (especially with the Lockheed Martin-built wideband code division multiple access payload that incorporates advanced technology to provide a 16-fold increase over legacy UHF SATCOM in the number and capacity of satellite links.) and providing simultaneous voice, data and video in real time. MUOS will also maximise the full feature capability of the future Joint Tactical Radio Systems (JTRS) terminals. Anticipated launch date for the first MUOS satellite is planned for 2010.

General Dynamics C4 Systems will lead the user-entry and integrated ground segments of the MUOS programme, supplying a secure ground network, satellite control and network management, and a JTRS-compliant terminal solution. BSS will provide a significant portion of the UHF payload capability. Harris Corporation will supply the MUOS spacecraft antenna. The team also includes Northrop Grumman.

Will implement the well known Wideband Code Division Multiple Access (WCDMA) waveform and Universal Mobile Telecommunications System (UMTS) standard.
