Geostationary Transfer Orbit


BSAT-2c was a geostationary communications satellite designed and manufactured by Orbital Sciences Corporation on the STAR-1 platform. It was stationed along its companion BSAT-2a from where they provided redundant high-definition direct television broadcasting across Japan.

The original companion for BSAT-2a was BSAT-2b, but a launch failure during its launch during July 2001, meant that it was not possible to commission it into service. Thus, in October of the same year, BSAT-2c was ordered and launched in June 2003. It was retired in August 2013.
