DoD wideband satellite communication services are currently provided by a combination of the existing Defense Satellite Communications System (DSCS) and Global Broadcast Service (GBS) satellites. In December 2019, Boeing announced that it had developed WGS-11, a new variant of its commercial 702 satellite, which can offer greater bandwidth efficiency and signal power than the previous satellites. Operation and usage of the system is broken into 3 segments. [3] According to United Launch Alliance, quoted on Spaceflight Now, "A single WGS spacecraft has as much bandwidth as the entire existing DSCS constellation. A description published by the Air Force calls the constellation the backbone of the U.S. militarys satellite communications adding the satellites themselves are its highest capacity communications satellites.. The third SOPS controls the spacecraft platform via unique software and databases designed by Boeing and fitted on the command and control segment consolidated (CCS-C) systems supplied by Integral Systems. The WGS consists of two segments. Typically, 702HP is equipped with a 490-Newton bipropellant apogee motor for the climb into Geostationary Orbit. The USSF Space Delta 8s 4th Space OperationsSquadron (4 SOPS) manages and controls the on-orbit satellite buses. [9][10] Originally, the second spacecraft was to fly on the Delta IV M+ (5,4), and the third on the Atlas V 421, but they were switched for an undisclosed reason.[11]. The history of U.S. MILSATCOM has been one of aggregation of mission capabilities over time. WGS hosts a powerful communications payload for secure and fault-proof communications. WGS 6 (USA 244) - Orbit. The Gapfiller System supports continuous 24 hour per day wideband satellite services to tactical users and some fixed infrastructure users. The Defense Department started placing WGS satellites in orbit in 2007. We use cookies to ensure that we give you the best experience on our website. After the launch, the military designated the WGS-1 as USA-195, which entered service in April 2008. 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). The narrower spot beams on WGS-11+ are designed to deliver a stronger, more reliable connection, said vice president of Boeing Government Satellite Systems Troy Dawson in the Boeing release. On April 19, 2019 Boeing Co., El Segundo, California, was awarded a not-to-exceed $605,000,000 firm-fixed-price modification (P00109) to previously awarded contract FA8808-10-C-0001 for the production of the Wideband Global Satellite Communication Space Vehicle 11. WGS was initiated to deliver newer and greater capabilities to the warfighter by deploying a constellation of high-throughput satellites to Geostationary Orbit. .

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. WGS10 was ordered in July 2012. The terminal segment refers to the users of the communication services provided by the WGS system. "[4] WGS operations are currently run by the 4th Space Operations Squadron, out of Schriever Space Force Base, as well as the 53rd Space Operations Squadron. 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." CONNA - North America AMSAT - North & South America OCSAT - Asia Pacific EMSAT - Europe and Africa IOSAT - India, CIS, Middle-East The combination of the Wideband Gapfiller Satellites, DSCS satellites, GBS payloads, wideband payload and platform control assets, and earth terminals operating with them has been referred to as the Interim Wideband System (IWS). Frequency of satellite TV, satellite TV channels, satellite TV set without a problem . 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 WGS constellation provides broadband communications for the U.S. military and allies. Tacticalforces rely on WGS to provide high-capacity connectivity betweenindividual users and the Defense Information Systems Network (DISN). WGS-5 and 6 were launched in 2013 followed by WGS 7 in 2015. Enabled by a constellation of low Earth orbit satellites, Starlink will provide fast, reliable internet to populations with little or no connectivity, including those in rural communities and places where existing services are too expensive or unreliable. Boeing illustration. WGS systems comprise three main segments, which are space, terminal and control. A digital channelizer divides the uplink bandwidth into nearly 1900 independently routable 2.6MHz subchannels providing any-coverage-to-any-coverage connectivity (including X-to-Ka and Ka-tocrossbanding) for maximum operational flexibility. 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. On 3 October 2007, Australia's Department of Defence announced that the country would fund a sixth satellite in the constellation. The space segment refers to satellites in orbit; WGS-1 was launched into orbit on 10 October 2007 on the United Launch Alliance (ULA) Atlas V launch vehicle.

The breakage of uplink bandwidth into approximately 1,900 independently routable 2.6MHz subchannels by a digital channeliser has increased the connectivity between uplink and downlink coverage areas. The Global Broadcast Service space segment was implemented in three phases. 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. Dec. 5, 2009 The satellite operates in the Indian Ocean region and provides high-capacity communication links to US troops in Iraq and Afghanistan. Ion thrusters generate thrust by accelerating ions through the use of an electric field and ejecting these ions at extremely high velocity creating thrust force propelling the spacecraft forward. . [14], On 23 August 2010, Boeing was awarded an Air Force contract worth US$182 million to begin work on the seventh WGS satellite. An artists illustration of the Wideband Global Satellite Communications satellite WGS-11+. map shows the quantized color-coded availability from each satellite's field of view based on the optimized data rate for the reference link which operates in a relatively benign propagation environment. The WGS-6 was delivered to the US Air Force in December 2013. Satellite Dish Pointer with Google Maps. About Contact Widget Social Media Facebook Twitter Instagram . The WGS-4 was launched atop the same vehicle and at the same location in January 2012 and was accepted by the US Air Force in April 2012.
