Perhaps  someone could forward this to the MilRadioComms list for  me.

Second  MUOS satellite gets new communications system module

Posted by John  McHale
SUNNYVALE, Calif., 1 May 2010

The second satellite in the  U.S. Navy's Mobile User Objective System
(MUOS) program now has a new  communications system module from
Lockheed Martin [NYSE:  LMT].

Supporting ultra-high frequency (UHF) satellite  communications
(SATCOM), MUOS will provide assured communications,  including
simultaneous voice, video, and data, for mobile  warfighters.

Designed and built by Lockheed Martin in Newtown, Pa., and  delivered
to the company's facilities in Sunnyvale, Calif., the module  features
a wideband code division multiple access payload that  incorporates
advanced technology to provide a 10-fold increase over legacy  UHF
SATCOM in the number and capacity of satellite links, Lockheed  Martin
officials say. These technologies will support new mobile  satellite
terminals that are under development for the Joint Tactical  Radio
System (JTRS).

The module also includes a legacy UHF payload  provided by Boeing
Defense, Space and Security in El Segundo, Calif., that  is compatible
with more than 10,000 deployed UHF SATCOM terminals that  will
transition to MUOS as existing UHF Follow-on (UFO) satellites  reach
the end of their on-orbit life.

Over the next few months,  Lockheed Martin will complete the final test
verification phase on the  system module, integrate it with the
spacecraft propulsion core module and  other space vehicle components,
and begin environmental and acceptance  testing of the fully integrated
space vehicle.

The first MUOS  satellite has completed Passive Intermodulation testing
and is currently  undergoing electromagnetic
interference/electromagnetic compatibility  testing in support of the
spacecraft Level Baseline Integrated System Test  (BIST). BIST testing
will characterize the overall performance of the fully  integrated MUOS
spacecraft and establish a performance baseline prior to  entering the
environmental test phase, which includes acoustic and thermal  vacuum
testing.

The first MUOS satellite, along with the associated  ground system
provided by General Dynamics C4 Systems, Scottsdale, Ariz.,  is
scheduled for on-orbit hand-over to the Navy in 2011.

Lockheed  Martin Space Systems in Sunnyvale, Calif., is the MUOS prime
contractor and  system integrator. The Navy's Program Executive Office
for Space Systems in  Chantilly, Va., and its Communications Satellite
Program Office in San  Diego are responsible for the MUOS program.
