Galaxy 16 satellite

Galaxy 16 is a C- and Ku-band satellite with 24 C-band and 24 Ku-band transponders to be delivered December 31, 2005

The spacecraft is a version of SS/L’s space-proven LS-1300 satellite platform, which has an excellent record of reliable operation. The geostationary LS-1300 has a designed service life of 15 years and maintains station-keeping and orbital stability by using bipropellant propulsion and momentum-bias systems.

Galaxy 16, a high-power fixed satellite service (FSS) spacecraft built for PanAmSat Corporation (NYSE: PA) by Space Systems/Loral (SS/L), was successfully launched today at 12:50 a.m. PDT. The satellite was delivered into a geosynchronous transfer orbit aboard a Sea Launch Zenit-3SL rocket from the Odyssey Launch Platform, positioned on the equator in the Pacific Ocean. Space Systems/Loral is a subsidiary of Loral Space & Communications (NASDAQ: LORL).

"Galaxy 16 illustrates SS/L's expertise in developing cost-effective, high-utility FSS spacecraft for use by the world's largest communications carriers," said Patrick DeWitt, president, Space Systems/Loral. "With a cost-effective integration of advanced satellite features and high performance, space-proven technology, Galaxy 16 will provide PanAmSat with the ability to deliver highly competitive and reliable services to their customers."

Weighing in at 4,640 kg (10,229 pounds), Galaxy 16 is designed to provide over 10 kilowatts of power throughout its 15-year mission life. The satellite's communications payload carries 24 high-power Ku-band and 24 C-band transponders. From its orbital location at 99 degrees West longitude, Galaxy 16 will provide coverage for data and video services, including high-definition television (HDTV) broadcasts and IPTV (Internet Protocol Television), across the entire United States, including Alaska, Hawaii and Puerto Rico, in addition to Canada and Mexico.

The satellite is the fourth spacecraft built for PanAmSat by SS/L. A fifth, Galaxy 18, is currently under construction at SS/L's facility in Palo Alto, Calif., scheduled for delivery in 2007.
