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. In early 2001, a satellite communications industry team led by Boeing Satellite Development Center, 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 Soldier, warfighter with newer and far greater capabilities than provided by current systems. In March 2007, the acronym WGS was changed to Wideband Global SATCOM. Just one WGS satellite provides more SATCOM capacity than the entire legacy Defense Satellite Communications System (DSCS) constellation.Satellite description
Built by Boeing Satellite Development Center, Boeing Satellite Systems, WGS F3 is based on the Boeing 702, BSS-702 satellite bus. It had a mass at launch of , and was expected to operate for fourteen years (to 2023]). The satellite is equipped with two Solar panels on spacecraft, solar arrays to generate power for its communications payload, which consists of military cross-band X band, X-band and Ka band, Ka-band Transponder (satellite communications), transponders. Propulsion is provided by a R-4D-15 Apogee kick motor, apogee motor, with four XIPS-25 ion engines for stationkeeping.Launch
WGS F3 was launched by United Launch Alliance (ULA), who placed it into orbit using a U.S.Con. Delta IV launch vehicle, which flew for the first time in the Medium+ (5,4) configuration. The launch took place from Cape Canaveral Space Launch Complex 37, Space Launch Complex 37B (SLC-37B) at the Cape Canaveral Space Force Station, Cape Canaveral Air Force Station (CCAFS), with at 01:47:00 Coordinated Universal Time, UTC on 6 December 2009 (5 December 2023, 20:47ET). The launch was successful, placing the satellite into a geostationary transfer orbit (GTO), from which it raised itself into geostationary orbit using its propulsion system. Following launch, the satellite was designated USA 211 under the List of USA satellites, U.S. military's designation system, and received the International Designator 2009-068A and Satellite Catalog Number 36108.Location
