USA-244, or Wideband Global Satcom 6 ( WGS-6) is an American military communications satellite operated by the United States Air Force as part of the Wideband Global Satcom programme. Launched in 2013, it was the sixth WGS satellite to reach orbit. It is stationed at a longitude of 104° east, in geostationary orbit. WGS-6 was procured by the Australian Defence Force for the US Air Force, in exchange for participation in the programme. [3 ]
Boeing, USA-244 is based around 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. [4 ]
USA-244 was launched by
United Launch Alliance, who placed it into orbit using an Delta IV Medium+(5,4) rocket, flight number D363. The launch took place from Space Launch Complex 37B at the Cape Canaveral Air Force Station, with liftoff at 00:29 UTC on 8 August 2013. The launch was successful, placing the WGS-6 into a [1 ] geosynchronous transfer orbit, from which the spacecraft raised itself into geostationary orbit using its onboard propulsion system. The satellite was designated USA-244 under the US military's designation system, and received the International Designator 2013-041A and Satellite Catalog Number 39222. [2 ] [5 ]
