Mobile User Objective Sys (MUOS)

Abstract

The Mobile User Objective System (MUOS) program provides for the development of the next generation Department of Defense (DoD) advanced narrowband communications satellite constellation. The current Ultra-High Frequency (UHF) Follow-On (UFO) constellation is projected to degrade below acceptable availability parameters in 2011. The MUOS Program requirements are baselined to the 15 January 2008 Capability Production Document (CPD) Increment 1 validated by Joint Requirements Oversight Council Memorandum (JROCM) 015-08, which was derived from the 17 July 2001 MUOS Operational Requirements Documents (ORD) as modified by JROCM 187-03, dated 23 September 2003. This MUOS Research Development Test & Evaluation, Navy (RDT&E,N) effort supports an On-Orbit Capability (OOC) in calender year (CY) 2011 and Full Operational Capability (FOC) in CY2015. A MUOS Risk Reduction & Design Development (RRDD) contract was awarded in September 2004 to Lockheed Martin after Key Decision Point (KDP) B. The approval at KDP-B in September 2004 officially designated the MUOS Program as a DoD Space Major Defense Acquisition Program. In FY 2011, MUOS efforts will be focused on completion of work on the assembly, integration and testing of satellite 1, satellite 1 shipment and launch vehicle mate operations and launch. Continue work on assembly, integration and testing of satellite 2. Complete development and test of follow-on versions of the CAI waveform. Complete ground systems software development/final qualification tests, as well as assembly/integration/factory acceptance tests. Complete site acceptance test at Wahiawa and Australia ground stations. Note: The Navy anticipates requesting a reprogramming to meet FY10 requirements. The UHF SATCOM Hosted Payload effort was funded to mitigate some of the long-term legacy UHF gap caused by projected UFO failures and the availability of the MUOS-compatible Joint Tactical Radio System (JTRS). FY09 funding supported the acquisition strategy development and contract planning efforts for the development of a UHF Hosted Payload capability. In February 2009, the Hosted Payload program was cancelled. Studies have identified methods to obtain a cost-effective, low risk path to implement legacy payload changes to mitigate any on-orbit losses of UHF capability and ensure continuity of legacy requirements. FY10 plan is to pursue additional UHF capability and incorporate into the MUOS spacecraft's final assembly and integration for Flight 1 and Flight 2.
