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 formerly in a geostationary orbit at 0°N 97°W / 0°N 97°W / 0; -97, 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 Intelsat. The satellite's main C-band transponder cluster covers the United States, southern Canada, and Mexico; its main K_u band transponder cluster covers the U.S., Mexico, and the northern Caribbean Sea. An additional C-band and a K_u band transponder pair targets the Hawaiian Islands.

Galaxy 25 has a projected life of 12 years. It was replaced by Galaxy 19 (formerly IA-9) in late 2008.^[1] When it was last in service at 97 degrees west, Galaxy 25 transmitted both free-to-air (FTA) direct-to-home (DTH) broadcasting and encrypted subscription channels / services. The replacement satellite, Galaxy 19 was successfully launched on September 24, 2008.^[2] Galaxy 25 has been moved to a different orbital position at 0°00′N 93°06′W / 0°N 93.1°W / 0; -93.1 where it is currently broadcasting several services on its K_u band transponders.
