Operation and usage of the WGS System is divided into three segments the Space Segment with the Satellites, the Control Segment which operates the satellites, and the Terminal Segment which corresponds to user terminals on the ground. WGS was initiated to deliver newer and greater capabilities to the warfighter by deploying a constellation of high-throughput satellites to Geostationary Orbit. XIPS, the Xenon Ion Propulsion System, has flown on numerous spacecraft and is ten times more efficient than the conventional chemical propulsion systems, the only disadvantage being the low thrust that can be achieved with the system leading to a longer time frame needed between launch and Beginning of Service. The Boeing 702 uses advanced technologies in propulsion, power generation and thermal control, and can connect X- and Ka-band users within the coverage field of view via reconfigurable antennas and a digital channeliser. WGS can tailor coverage in near-real time and connect X-Band and Ka-Band Users anywhere within the field of view.
