USA-195, orWideband Global SATCOM 1 (WGS-1) is a United States militarycommunications satellite operated by theUnited States Air Force as part of theWideband Global SATCOM programme. Launched in 2007, it was the first WGS satellite to reach orbit. It is stationed at alongitude of 174.8° East (Ocean Pacific).[3]
The WGS system is a constellation of highly capable military communications satellites that leverage cost-effective methods and technological advances in the communications satellite industry. The WGS system is composed of three principal segments: Space Segment (satellites), Control Segment (operators) and Terminal Segment (users). Each WGS satellite provides service in multiple frequency bands, with the unprecedented ability to cross-band between the two frequencies on board the satellite. WGS augments other satellites.[4]
In early 2001, a satellite communications industry team led byBoeing Satellite Systems was selected to develop the Wideband Gapfiller Satellite (WGS) system as successors to theDefense Satellite Communications System (DSCS) series of communications satellites. This satellite communications system is intended to support thewarfighter with newer and far greater capabilities than provided by current systems. In March 2007, the acronym WGS was changed to Wideband Global SATCOM.[5]
Just one WGS satellite provides more SATCOM capacity than the entire legacy Defense Satellite Communications System (DSCS) constellation.[4]
Built byBoeing, USA-195 is based on theBSS-702satellite bus. It had a mass at launch of 5,987 kg (13,199 lb), and was expected to operate for fourteen years. The satellite is equipped with twosolar arrays to generate power for its communications payload, which consists of cross-bandX-band andKa-bandtransponders. Propulsion is provided by an R-4D-15apogee motor, with fourXIPS-25ion engines for stationkeeping.[5]
WGS-1 was launched byUnited Launch Alliance (ULA), who placed it into orbit using anAtlas Vlaunch vehicle flying in the 421 configuration. The launch took place fromSpace Launch Complex 41 at theCape Canaveral Air Force Station (CCAFS), with liftoff occurring at 00:22UTC on 11 October 2007.[1] The launch was successful, placing the satellite into ageosynchronous transfer orbit (GTO), from which the spacecraft raised itself intogeostationary orbit using its onboard propulsion systems. The satellite was designated USA-195 under theU.S. military's designation system, and received theInternational Designator 2007-046A andSatellite Catalog Number 32258.[1][6]
