Boeing successfully launched the WGS-2 into geostationary orbit on the Atlas V in April 2009. On 3 October 2007, Australia's Department of Defence announced that the country would fund a sixth satellite in the constellation. [16][17], WGS-9 (USA-275) was launched on 19 March 2017, at 00:18:00 UTC. directed the acquisition of two additional WGS satellites. WGS-11+ is expected to include advanced digital payload and operational capabilities that improve on those of its predecessors. These satellites operate in the programmed X- and Ka-band frequency spectrum. DOD considered accelerating AEHF by 18 months but later agreed to have a 3-year gap from last MILSTAR and the first AEHF launch. Each standard WGS satellite offers 4.875 GHz of instantaneous switchable bandwidth corresponding to a capacity of 2.1 to 3.6 Gbps depending on the ground terminals, data rates and modulation profiles that are employed. It is available in different medium models: medium+ (4,2), medium+ (5,2), medium+ (5,4) and heavy. The Program Office plan for WGS satellite launch is to integrate them on both Delta and Atlas Evolved Expendable Launch Vehicles (EELVs). If you continue to use this site we will assume that you are happy with it. The Option for WGS4 and 5 was exercised in November 2006. The engine provides a specific impulse of 312s, has a thrust to weight ratio of 13.7 and operates at a chamber pressure of 6.9 bar. The Global Broadcast Service [GBS] augments and interfaces with other communications systems to provide a continuous, high-speed, one-way flow of high-volume information supporting routine operations, training and military exercises, special activities, crisis, situational awareness, weapons targeting, intelligence, and the transition to and conduct of operations short of nuclear war. Mapping provided by https://hilltopviews.org.uk. 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. Dec. 7, 2016 The first launch was on Delta and the second on Atlas. The WGS system is composed of three principal segments: the Space Segment (satellites), the Control Segment (operators), and the Terminal Segment (users). Ford. On January 16, the U.S. Army posted a request for information on a Wideband Global Satellite (WGS) Ka-Band Satellite Surrogate. Atlas V is equipped with 4m-diameter payload fairing, two solid rocket motors and a single-engine Centaur upper stage, attached to a single common core booster (CCB) powered by an RD-180 engine.
