SSL-built communications satellite for SKY Perfect JSAT is performing post-launch manuevers according to plan

Palo Alto, CA - Space Systems Loral (SSL) a leading provider of innovative satellites and spacecraft systems, today announced that a satellite designed and built for SKY Perfect JSAT Corporation, a leading satellite operator based in Japan, was launched on Saturday night and is successfully performing post-launch maneuvers according to plan. The satellite, JCSAT-16, deployed its solar arrays on schedule following the SpaceX Falcon 9 launch from Cape Canaveral Air Force Station in Florida. JCSAT-16, which will provide service for video distribution and data transfer communications, began firing its main thruster early today, to navigate toward its final geostationary orbit.

“I would like to congratulate SKY Perfect JSAT and SpaceX on another successful launch, the second this year for our three companies working together,” said John Celli, president of SSL. “We are honored to provide SKY Perfect JSAT with another important satellite for its fleet, and look forward to working closely together again on the launch of JCSAT-15, which is scheduled to take place later this year.”

JCSAT-16 is an 8.5-kW multi-mission satellite designed to function as an in-orbit back-up for multiple orbital locations that will ensure stability for existing services and further strengthen SKY Perfect JSAT Corporation’s business. The satellite, which has both Ku- and Ka-band capabilities, will serve the Japanese market from multiple orbital locations.

“SSL is a valued and reliable partner, which has now provided two satellites for us this year,” said Shinji Takada, Representative Director, President and CEO of SKY Perfect JSAT. “We look forward to integrating JCSAT-16 into our fleet and further strengthening the stability of our services for our customers.”

JCSAT-16 is based on the highly flexible SSL 1300 platform, which has the capability to support a broad range of applications and technology advances. SSL is also building JCSAT-15, which is expected to launch later this year.
