USA-195, or Wideband Global SATCOM 1 (WGS-1) is a United States 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 (Ocean Pacific).[3]
Overview
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 by Boeing Satellite Systems was selected to develop the Wideband Gapfiller Satellite (WGS) system as successors to the Defense Satellite Communications System (DSCS) series of communications satellites. This satellite communications system is intended to support the warfighter 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]
