The Lockheed-Martin corporation has released that the Mobile User Objective
System (MUOS) will employ third-generation (3G) commercial cellular technology
to provide improved and assured communications to US warfighters. This
announcement was made public by Lockheed-Martin, as MUOS prime integrator, at
MILCOM 2004 in Monterey, California.
is an advanced narrowband tactical satellite communications system that will
replace the current Ultra High Frequency Follow-On (UFO) system beginning in
2010 following the first MUOS spacecraft launch. In addition, MUOS will be fully
compatible with existing UFO system and associated legacy terminals. Military
communications availability will be increased by leveraging proven 3G commercial
cellular advancements, which represent significant improvement over previous
MUOS will rely upon the MUOS 3G Wideband Code Division Multiple Access (WCDMA)
waveform and the Universal Mobile Telecommunications System (UMTS)
infrastructure to transmit text, voice, video and multimedia to a wide range of
platforms, including 'always-on' connection handheld terminals that will be
significantly faster than previous systems. MUOS will integrate seamlessly with
the future Joint Tactical Radio System (JTRS) making possible full exploitation
of JTRS features as well.
Lockheed-Martin team is currently under a $2.1 billion contract for development
and manufacturing of two satellites and associated ground control elements on
behalf the US Navy Space and Naval Warfare Systems Command (SPAWAR). The
contract could be as high as $3.26 billion executing all options on three
additional spacecraft. Final assembly and test will occur at Lockheed-Martin
Space Systems facilities in Sunnyvale, California.
