Wideband Global SATCOM Satellite (WGS) is the backbone of the U.S. military's Wideband satellite communications capability. Boeing conducted a ground test for a Ka-band SATCOM antenna system for installation in the spacecraft in January 2011. Dominic This year, resiliency is baked into all the conversations, said assistant secretary of Defense for space policy John, The Space Force and the Pentagon have put considerable effort into making proliferating satellite constellations to make them more resilient against attack, but the ground stations and networks that communicate with those satellites pose a backdoor risk through which adversaries could potentially attack space capability, said Chief of Space Operations, The Space Force must transition from delivering behind-the-scenes support to playing a more active role in which space capabilities are continuously tested and contestedand it must do so in as short a time as possible, said Chief of Space Operations Gen. B. These characteristics provide a quantum leap in communications capacity, connectivity and flexibility for U.S. military forces and. SATCOM Services. It provides services to the US DoD and Australian Department of Defence. A satellite's latitude () is the latitude of the point These characteristics provide a quantum leap in communications capacity, connectivity and flexibility for U.S. military forces and international partners while seamlessly integrating with current and future X- and Ka-band terminals. The block II satellites meet the bandwidth requirements of war-fighters, thereby providing information exchange, enabling execution of tactical command and control, communications and computers, intelligence, surveillance, reconnaissance (C4ISR), battle management and combat support information. WGS-7 and WGS-8 were launched in July 2015 and December 2016 respectively. Boeing received a $338.7m contract modification to build WGS-10 in July 2012. The original RD-4 was developed as an attitude control thruster for the Apollo Service and Lunar Lander modules. 1 priority in 2022, with proliferated constellations of satellites a focus of this program to ensure systems remain operable even if some elements are lost. High-capacity military communications satellite, 39 125-MHz Channels via digital channeliser/router. Limited protected services are provided under conditions of stress to selected users employing terrestrial modems capable of providing protection against jamming. A description published by the Air Force calls the constellation "the backbone of the U.S. military's satellite communications" adding the satellites themselves are its "highest capacity communications satellites." Data can be delivered in the form of unclassified, in-the-clear broadcast signals and fully encrypted signals received by large platforms on ships and aircraft down to communications packages carried by individual soldiers. If you continue to use this site we will assume that you are happy with it. The system will provide capacity ranging from 2.1 Gbps to more than 3.6 Gbps to tactical users, depending on the mix of ground terminals, data rates and modulation schemes employed. Features The WGS constellation provides broadband communications for the U.S. military and allies. Boeing and the U.S. Air Force MILSATCOM Systems Wing have signed in October 2006 a $1.067billion contract for up to three more Wideband Gapfiller Satellites (WGS), if all options are exercised. S.O.S./911 coverage for the device only applies to areas shown above. In return, the Australian Defence Ministry was given access to the data sent by the sixth satellite, which was developed to increase the bandwidth capacity of US forces.
