The Space Systems/Loral (SSL)-built MBSAT broadcast communications satellite launched successfully at 12:40 EST March 13. The satellite was carried on an International Launch Services Atlas III rocket from Cape Canaveral Air Force Station.

SS/L built the MBSAT bird for Mobile Broadcasting Corp. of Japan and SK Telecom of Korea. It will be positioned at 144 degrees East longitude, and it will deliver high-quality music, video and data to mobile users in Japan and Korea through a variety of mobile terminals.

The satellite carries two high-powered transponders for direct broadcasting services and two additional transponders that provide links to terrestrial repeater networks, which augments the satellite broadcast signal. Each transponder has an operating bandwidth of 25 megahertz, Loral Space and Communications said. The satellite is expected to have a 12- year lifespan.
