In 2019, Boeing received a contract to build an 11th WGS satellite. The new satellite is destined to join a constellation of 10 other WGS satellites in high geosynchronous Earth orbits providing communications to deployed forces. Large swatches of America have little or no coverage. Boeings team of contractors includes Harris Corporation, ITT Industries, Logicon and SAIC. WGS systems feature digitally channelised transponder satellites that provide communication capacity, connectivity and flexibility to the US military forces. The WGS system iscomposed of three principalsegments: Space Segment(satellites), Control Segment(operators) and TerminalSegment (users). The Block II satellites are similar to the three Block I satellites already in production. WGS-11+ is expected to include an advanced digital payload and operational capabilities that improve on those of its predecessors. Payload commanding and network control are managed by the armys 53rd Signal Battalion at Peterson AFB, Colorado, with subordinate elements at seven locations. Chance Saltzman in a weekend address to Air, The recently-concluded Juniper Oak, an all domain exercise carried out from Jan. 23-26, was the largest U.S.-Israel partnered exercise in history, according to U.S. Central Command. The digital channeliser also offers multicast and broadcast services to support the network protocol. It was followed by the launch of the WGS-5 in May 2013 and that of the WGS-6 in August 2013. WGS is based on Boeings BSS-702HP satellite platform, the high-power configuration of the 702 bus that can support the most powerful communications payloads with state of the art onboard systems including precise pointing capability and the use of flight-proven components and built-in redundancy to ensure the satellite meets its in-orbit lifetime of 15 years. It was launched on a Delta IV Medium+ (5,4) launch vehicle. Each WGS satellite is digitally channelized and transponded. Users of WGS include the U.S., Canada and Australia. The U.S. Department of Defence selected Boeing Space Systems in 2001 for the WGS satellites as a replacement for the Defense Satellite Communications System 3 in operation from the 1980s into the 2000s. The Air Force Space Command estimates each satellite will cost approximately US$300 million. 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. July 23, 2015 Work will be performed in El Segundo, California, and is expected to be complete by Nov. 20, 2023. The Army relies on Ka and Ku band satellite communications (SATCOM) for beyond line of sight (BLOS) communications between Division, Brigade, Battalion, and Company echelons. WGS provides two-way X-band and Ka-band communications as well as Ka-band broadcast services to US Armed Forces and other agencies worldwide. The next satellite in the Air Force's Wideband Global SATCOM family of satellites will be able to deliver twice the capability of the entire constellation to war fighters thanks to commercial technology. The Wideband Global SATCOM system (WGS) is a high capacity United States Space Force satellite communications system planned for use in partnership by the United States Department of Defense (DoD), Canadian Department of National Defence (DND) and the Australian Department of Defence. click here. The WGS satellites make use of modern satellite communications systems such as phased array antennas and digital signal processing technology to create a powerful architecture with a high degree of flexibility. 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. Boeing conducted a ground test for a Ka-band SATCOM antenna system for installation in the spacecraft in January 2011. The DoD wideband satellite communications system consists of multiple types of military satellites, control facilities, and user terminals that comprise three distinct segments: (1) the User Terminal Segment, (2) the Space Segment, which consist of three Gapfiller Satellites in geo-synchronous orbit, each providing a two way X-band, a new two way military Ka-band, and broadcast Ka-band services, and (3) the Control Segment. The satellite operators in charge of commanding and monitoring the satellite's bus and payload systems as well as managing the network operating over the satellite are the control segment. The Delta IV's Delta Cryogenic Second Stage deployed the satellite as planned on 8 December 2016, at 00:35 UTC. No other alternatives to the WGS program had been identified by the MILSATCOM Joint Program Office (SMC/MCX). The Global Broadcast Service space segment was implemented in three phases. The WGS consists of two segments. Sens. Slow Medium Fast. SSC Space US has supported launch and early orbit checkout operations for all eight WGS satellites and the Boeing/SSC partnership will continue in the future with the WGS-9 and WGS-10 missions. Background It enables a user to inquire about satellite imagery over any portion of the world by specifying a nominal scene center designated by PATH and ROW numbers. SSC is proud to be in a long-term relationship with Boeing on this important mission providing safe and secure critical communications, said Erik Eliasen, Vice President of National Security Space Programs for SSC Space US. The DSCS system was replaced by five fully operational Wideband Gapfiller Satellites (WGS), each able to downlink 2.4 Gbps of data to tactical users. It is available in different medium models: medium+ (4,2), medium+ (5,2), medium+ (5,4) and heavy. Required power varies between 1,300 and 4,500 Watts achieving a thrust of up to 165 Millinewtons and a specific impulse of 3,500 seconds. One major upgrade provided by WGS is X-Ka-Band inter-connectivity delivered by a digital channelizer which divides the uplink bandwidth into independently routable 2.6MHz subchannels which can be converted from Ka-to-X-Band and vice versa. Core U.S. MILSATCOM will span just 14 satellites by 2020 [Advanced EHF (AEHF): 4, Wideband Global SATCOM (WGS): 6, Mobile User Objective System (MUOS): 4]. Ford. 3 hours 6 hours 12 hours 24 hours. 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. The next three, WGS satellites 4, 5, and 6, make up Block II. Two of the four thrusters are used as primary units at any given time and stationkeeping in Geostationary Orbit will require four burns for a total of about 30 minutes per day to maintain the satellite within a 0.01 degree stationkeeping zone which allows many satellites to be collocated in a single orbital slot. Each individual beam is shapeable and can be uniquely tailored to each situation. An artists illustration of the Wideband Global Satellite Communications satellite WGS-11+. }, Page last modified: It provides steerable spotbeams that can reach any position within the satellites field of view between 65 degrees north and south latitude. WGS 5 extended the Wideband Global SATCOM constellation to the Americas for a host of users following launch in May 2013. Each WGS satellite provides service in both the X and Ka frequency bands, with the unprecedented ability to cross-band between the two frequencies onboard the satellite. Timezone: 51.51N Phase III is an Objective capability planned as part of the Advanced Wideband System (AWS) I FY 2009-Plus. Subsequently, the The result has been today's limited number of large satellites of ever-increasing complexity. The Army is acquiring the ground control segment and the 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.
