The US Air Force extended the order value to $1.09bn in September 2011 to facilitate the production, launch and on-orbit activation of the seventh satellite and to procure the long lead materials for an eighth WGS satellite. Logicon provides communications software and SAIC extends engineering and communications architectures. WGS 3-WGS F3-12W-KA band footprint-beam-coverage : WGS 1+2+3 - Global beams, geographical . Its coverage area stretches from the West Coast of the United States to Southeast Asia. EN . The system provides two-way X- and Ka-band communications, as well as Ka-band broadcast services to the US armed forces and other allied forces worldwide, and X-band satellite transfers of data, photos and videos to troops on the battlefield. The Gapfiller satellites must either be backward compatible with, or allow for the affordable upgrade of, the existing terminal populations in use with the DSCS and GBS systems. The Gapfiller satellites serve as the means to continue and increase the capability of wideband services until the introduction of the Objective or Advanced Wideband System. 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-4 (USA-233), the first satellite of the Block II, was launched by United Launch Alliance (ULA) from SLC-37B at the Cape Canaveral Air Force Station (CCAFS) by a Delta IV M+ (5,4) on 20 January 2012, at 00:38:00 UTC. There was a continuing need for these users to access the Gapfiller satellites and the two or more DSCS III SLEPs to provide worldwide coverage. Due to the early loss of a MILSTAR satellite, DOD committed to the purchase of 4 AEHF satellites plus one spare. WGS The Wideband Global Satcom System is a U.S. satellite constellation providing communications for military operations around the globe, supporting soldiers, ships, and aircraft including unmanned drones used for surveillance and intelligence gathering operations around the globe. Please make a donation to support Gunter's Space Page. The new channelizer makes use of the latest Application Specific Integrated Circuit technology to be more efficient in converting uplinked data to digital signals which can then be moved internal to the satellites ahead of reconversion and downlink. The WGS system is composed of three principal segments: Space Segment (satellites), Control Segment (operators) and Terminal Segment (users). It provides services to the US Department of Defense and the Ministry of Defense for Canada as well as other Government and Allied users under unstressed conditions. These characteristics provide a quantum leap in communications capacity, connectivity and flexibility for U.S. military forces and. Official U.S. government information about the Global Positioning System (GPS) and related topics The history of U.S. MILSATCOM has been one of aggregation of mission capabilities over time.

It is positioned over the Eastern Atlantic at an orbital slot of 12> West longitude to operate in the Atlantic region. Beginning in 1998, GBS broadcasts via communication payloads on two UFO Ka-Band augmented satellites. To take advantage of WGS' increased capabilities, STAR-T was upgraded by adding a fourth band (Ka), making it a quad-band terminal. Background The WGS Fleet is controlled by four Army Wideband Satellite Operation Centers that receive telemetry and send commands to up to three satellites per center. It is principally designed and developed for the US Department of Defence (DoD). The satellite operates in the Indian Ocean region and provides high-capacity communication links to US troops in . Other improvements involve uniquely shaping the terrestrial footprint of the beams for smaller footprints that are less susceptible to jamming. Fiscal 2018 procurement funds in the amount of $300,000,000 are being obligated at the time of award. Installation of satellite TV; Satellite News; TV of the world; Contacts; Search. The WGS satellites will complement the DSCS III Service Life Enhancement Program (SLEP) and GBS payloads and will offset the eventual decline in DSCS III capability. The Defense Department started placing WGS satellites in orbit in 2007. WGS is designed to enhance and augment heritage communications from the DSCS-3 satellites, delivering Super High Frequency (SHF) wideband communications, and Ka-band Global Broadcast Service (GBS). WGS offers 4.875 GHz of instantaneous switchable bandwidth, thus each WGS can supply more than 10 times the capacity of a DSCS III Service Life Enhancement Program (SLEP) satellite. WGS was developed to replace the legacy 14-satellite US Defense Satellite Communications System (DSCS) constellation, launched from 1982 to 2003. As the backbone of the U.S. military's global satellite communications, WGS provides flexible, high-capacity communications for the Nation's warfighters through procurement and operation of the satellite constellation and the associated control systems. The XIPS-25 system used by the 702SP spacecraft consists of a central Xenon tank and four 25-centimeter ion thrusters. WGS-2 is operated by third SOPS at 50th Space Wing, Schriever AFB, under the operational command of the Joint Functional Component Command (JFCC) SPACE at Vandenberg AFB, California. WGS augments the one-way Global Broadcast Service (GBS) service through new two-way Ka-band service. launches following at approximately six-month intervals.

The U.S. Air Force Space and Missile Systems Center is harnessing advanced satellite communication technology from the private sector through the Wideband Global SATCOM (WGS) 11+ platform and its Pathfinder effort.The WGS-11+ effort is centered on capabilities that will provide more coverage beams, beam-formed bandwidth and frequency re-use than existing legacy systems, according to a release . Limited protected services are provided under conditions of stress to selected users employing terrestrial modems capable of providing protection against jamming. 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). Hoping to prod a debate on the Space Force's future, Chief of Space Operations Gen. B. Try reducing the number of spacecraft selected if the map is slow to respond. The method of ion acceleration varies between the use of Coulomb and Lorentz force, but all designs take advantage of the charge/mass ratio of the ions to create very high velocities with very small potential differences which leads to a reduction of reaction mass that is required but also increases the amount of specific power compared to chemical propulsion. The satellite was partially-funded by allied nations, including Canada, Denmark, the Netherlands, Luxembourg, New Zealand and the United States, for military access to the entire WGS constellation.[18]. WGS-5 and 6 were launched in 2013 followed by WGS 7 in 2015.
