1991-028A
Contel ASC's second ASC satellite, ASC 2, was launched in 1991 while Contel was merging with GTE. Once on-orbit, it was renamed Spacenet 4, part of the GTE Spacenet system. It took over the services provided by ASC-leased transponders on the Westar system. In 2003 the satellite supported the SES Americom Worldsat network over the Pacific and was being used in collaboration with SCC.
