SSL-built satellite for Sirius XM Radio successfully performs post-launch 
maneuvers 
PALO ALTO, CA, Oct. 28, 2013 /CNW/ - Space Systems/Loral (SSL, a leading 
provider of commercial satellites, today announced that the Sirius FM-6 
satellite, designed and built for Sirius XM Radio, is performing post-launch 
maneuvers according to plan. The satellite deployed its solar arrays late 
Friday evening, following a successful launch from the Baikonur Space Center 
in Kazakhstan aboard a Proton Breeze M launch vehicle, provided by 
International Launch Services (ILS). Yesterday, it began the first of 
several thruster firings to maneuver into geosynchronous orbit. 
Sirius FM-6 is a high-power, 20-kilowatt satellite that has an X-band uplink 
and an S-band downlink payload. It has a nine-meter unfurlable reflector, 
built by Harris Corporation, which allows for broadcast to cars and satellite 
radios for the home, office and to mobile devices. 
The first three satellites built by SSL for SiriusXM were placed in a unique 
near-polar orbit and have provided uninterrupted service throughout their 
life. Sirius FM-6 is the third high power geostationary (GEO) satellite 
built by SSL for SiriusXM. 
Sirius FM-6 will help ensure continuous and reliable delivery of SiriusXM's 
unparalleled audio entertainment and data services to 25.6 million subscribers 
across North America. 
"Our close collaboration with SiriusXM over the years has resulted in some of 
the world's most powerful spacecraft," said John Celli, President of SSL. "It 
has been an honor to work with SiriusXM, and to contribute to the success of 
satellite radio, which brings popular entertainment and important information 
to millions of people in their cars, homes and businesses." 
Sirius FM-6 is SSL's tenth 20-kilowatt satellite to be placed into orbit. It 
is based on the SSL 1300 space-proven platform, which has a long history of 
reliability and provides the power and flexibility to support a broad range of 
applications and technology advances. With this launch, there are 74 
SSL-built satellites currently on orbit.
