From Wikipedia, the free encyclopedia
Galaxy 25 (G-25) launched in 1997, formerly known as Intelsat Americas 5 (IA-5) until February 15, 2007 when it was renamed as result of the merger between owner Intelsat and PanAmSat or Telstar 5) is a medium-powered communications satellite in a geostationary orbit at 97.0 degrees west, above a point in the Pacific Ocean several hundred miles west of the Galapagos Islands. It was manufactured by Space Systems/Loral, part of its FS-1300 line, and is currently owned and operated by PanAmSat. The satellite's main C-band transponder cluster covers the United States, southern Canada, and Mexico; its main Ku-Band transponder cluster covers the U.S., Mexico, and the northern Caribbean Sea. An additional C-band and a Ku-Band transponder pair targets the Hawaiian Islands.
Galaxy 25 has a projected life of 12 years, is scheduled to be replaced in the third quarter of 2008 by Galaxy 19 (formerly IA-9).[1] Galaxy 25 transmits both free-to-air (FTA) direct-to-home (DTH) broadcasting and encrypted subscription channels / services.
