Two-way Ka- (1GHz) and X-Band (500MHz) communications are supported by the Spacecraft which also provides a capability to convert signals from one to the other with its onboard systems. In addition, the channelizer supports multicast and broadcast services and provides an extremely effective and flexible uplink spectrum monitoring capability for network control. In March 2007 the acronym WGS was changed to Wideband Global Satcom. Red dots are reference stations used within the current network. 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].
Power is stored in dual Lithium-Ion batteries and dedicated avionics regulate the main power bus of the spacecraft to provide power to all subsystems of the satellite bus and the communications payload. 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. Additionally, the Satellite Control Network will also use the WGS in a similar manner as the DSCS III constellation is used to route ATM packets through the Defense Information Systems Agency (DISA) "cloud" to establish command and control streams with various satellite constellations. General Characteristics
The constellation of WGS satellites increases the communications capabilities of the militaries of the United States, Canada, and Australia by providing additional bandwidth and communications capabilities for tactical command and control, communications, and computers; intelligence, surveillance, and reconnaissance (C4ISR); battle management; and combat support information. The satellite operators come under the control segment. WGS-3 (USA-211) was launched on 6 December 2009, at 01:47:00 UTC, covers the Atlantic Ocean. Beginning in FY 2005 additional GBS Phase II coverage and capacity is provided by launch of three Wideband Gapfiller Satellite (WGS). Each WGS satellite has a launch mass of around 5,987 Kilograms and is based on Boeings BSS-702HP satellite platform. The order for long lead items for WGS7 was placed in August 2010. WGS 8, launched in 2016, marks the first in the Modified Block II satellites, hosting an upgraded digital channelizer which enables a 90% improvement in available bandwidth compared to previous WGS spacecraft. Map denotes coverage for satellite two-way voice and duplex data only. No other alternatives to the WGS program had been identified by the MILSATCOM Joint Program Office (SMC/MCX). 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." 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. 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. The WGS provide near-term continuation and augmentation of the services currently provided by the Defense Satellite Communications System (DSCS) and the Global Broadcast Service (GBS) Ka services currently provided by GBS payloads on UFO satellites. The WGS satellite delivers 19 independent coverage areas divided in eight steerable/shapeable X-Band beams delivered by separate transmit and receive arrays, ten steerable Ka-Band beams provided by ten independently steerable dish antennas and one X-Band Earth Coverage beam. WGS also augments the current Ka-band Global Broadcast Service (on UHF F/O satellites) by providing additional information broadcast capabilities as well as providing new two-way capability on that band. 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. Chance Saltzman unveiled his "Theory of Success" concept Feb. 22, as the force carves out its military role. The dashed part of the orbit path shows where the satellite is in the earth's shadow, The satellite was launched by a Delta IV M+ (5,4) launch vehicle, originally an Atlas V 421 but replaced with WGS-2.
