USA-195, or Wideband Global Satcom 1 (WGS-1) is an American military communications satellite operated by the United States Air Force as part of the Wideband Global Satcom programme. Launched in 2007, it was the first WGS satellite to reach orbit. It is stationed at a longitude of 174.8° east.
Built by Boeing, USA-195 is based on the BSS-702 satellite bus. It had a mass at launch of 5,987 kilograms (13,199 lb), and was expected to operate for fourteen years. The spacecraft is equipped with two solar arrays to generate power for its communications payload, which consists of cross-band X and Ka band transponders. Propulsion is provided by an R-4D-15 apogee motor, with four XIPS-25 ion engines for stationkeeping.
USA-195 was launched by United Launch Alliance, who placed it into orbit using an Atlas V rocket flying in the 421 configuration. The launch took place from Space Launch Complex 41 at the Cape Canaveral Air Force Station, with liftoff occurring at 00:22 UTC on 11 October 2007. The launch was successful, placing the satellite into a geosynchronous transfer orbit, from which the spacecraft raised itself into geostationary orbit using its onboard propulsion systems. The satellite was designated USA-195 under the US military's designation system, and received the International Designator 2007-046A and Satellite Catalog Number 32258.
