Features 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). WGS provides worldwide, flexible, high-capacity communications for US Government Agencies, Department of Defense (DOD), multiple International Partners and the North Atlantic Treaty Organization (NATO). Based on the Boeing BSS-702 bus, the satellite will have a dry mass of more than 3,000kg and will produce more than 11kilowatts of power at the end of its 14-year design life. WGS-11+ is expected to include advanced digital payload and operational capabilities that improve on those of its predecessors. Delivers IP-based voice, video, and data networking Set up and point the terminal in 30 minutes or less Ruggedized, packable, lightweight terminal With a simple feed-arm swap, the Viasat MMT operates over commercial Ku-, WGS Ka-, ViaSat-1 and ViaSat-2 Ka-, and commercially available X-band constellations. Block I contains WGS-1, WGS-2 and WGS-3 satellites, while block II satellites include WGS-4, WGS-5 and WGS-6. WGS-10 is the latest part of a constellation of highly-capable communications satellites that serve the armed forces of the United States and its allies.

If the WGS Program did not go forward, DoD satellite communication capabilities would be at risk and would not be adequate to meet DoD's future and increasing communication requirements. WGS systems enhance the DoDs communication services provided by the defence satellite communications system (DSCS) satellites and the global broadcast system (GBS) operating at an ultra-high frequency (UHF). Canada has also signed on to become a partner.[5]. The Option for WGS4 and 5 was exercised in November 2006. Oct. 10, 2007 At the time the program passed its preliminary design review in October 2020, contractor Boeing said delivery was on track for 2024. A coverage footprint of 200-400 miles . The Australian Government provided A$927m ($822.7m) in funding for ground infrastructure of the sixth WGS satellite under a memorandum of understanding (MoU) signed with the DoD in 2007. The first satellite was scheduled to launch in early 2004, with the second one to follow in 2005, both aboard a U.S. Air Force Evolved Expendable Launch Vehicle. SATCOM Services. The versatile reachback capability offered by the STAR-T/WGS combination strongly supports force-projection operations emphasized in both the Army's transformation strategy and Joint Vision 2020. These satellites have a much smaller coverage fraction f than does GPS, typically limited by a sensor's field of view. Hoping to prod a debate on the Space Force's future, Chief of Space Operations Gen. B. INPE Image Catalog is a go-to source of free satellite imagery maps of South and Central America, and Africa only. 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. .
