Galaxy 25
Galaxy 25 launched in 1997, contracted by International Launch Services, formerly known as Intelsat Americas 5 until 15 February 2007 when it was renamed as result of the merger between owner Intelsat and PanAmSat for Telstar 5, is a medium-powered communications satellite formerly in a geostationary orbit at 97° West, above a point in the Pacific Ocean several hundred miles west of the Galapagos Islands. It was manufactured by Space Systems/Loral using its LS-1300 satellite bus and is currently owned and operated by Intelsat. The satellite's main C-band transponder cluster covers the United States, Canada, and Mexico; its main Ku-band transponder cluster covers the United States, Mexico, and the Northern Caribbean Sea. An additional C-band and a Ku-band transponder pair targets Hawaii.
Galaxy 25 has a projected life of 12 years. It was replaced by Galaxy 19 in late 2008. When it was last in service at 97.1° West, Galaxy 25 transmitted both Free-to-air direct-to-home broadcasting and encrypted subscription channels / services. The replacement satellite, Galaxy 19 was successfully launched on September 24, 2008. Galaxy 25 has been moved to a different orbital position at 93.1° West where it is currently broadcasting several services on its Ku band transponders.
