This enables increased mission flexibility and . 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. 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. Coverage Maps. At the time the program passed its preliminary design review in October 2020, contractor Boeing said delivery was on track for 2024. One of the NATO systems using satellite communications from NSS6G is the Alliance Ground Surveillance (AGS) system. The first launch of WGS-1 was conducted by United Launch Alliance (ULA) on 11 October 2007, at 00:22 UTC. [1] The system is composed of the Space Segment satellites, the Terminal Segment users and the Control Segment operators.[2]. 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. Thus, each WGS can supply more than 10times the capacity of a DSCS-3 Service Life Enhancement Program (SLEP) satellite. WGS-4 is an extremely advanced satellite operating at the established X-Band and the high frequency Ka-Band. 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. 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. 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. In March 2007 the acronym WGS was changed to Wideband Global Satcom. Step 1. The WGS system is composed of three principal segments: Space Segment (satellites), Control Segment (operators) and Terminal Segment (users). [7] Once in their orbits at an altitude of 35,900km (22,300mi), each will weigh approximately 3,400kg (7,500lb).

With an initial launch scheduled for mid-2004 aboard an Air Force Evolved Expendable Launch Vehicle, WGS will provide early transformational capabilities supporting government objectives for a Transformational Communications Architecture in 2009 and beyond. 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 WGS constellation provides broadband communications for the U.S. military and allies. 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. The Gapfiller System supports continuous 24 hour per day wideband satellite services to tactical users and some fixed infrastructure users. [8] The next four, WGS-7, -8, -9, and -10, make up Block II Follow-On. Each individual beam is shapeable and can be uniquely tailored to each situation. (Courtesy of Boeing), WIDEBAND GLOBAL SATCOM SATELLITE Dianne Feinstein (D-Calif.) and Marco Rubio (R-Fla.) introduced the Space National Guard Establishment Act on, The Space Force is opening up its competition for rocket launches with a dual-lane approach, according to a new draft request for proposals (RFP) from industrypotentially giving smaller companies more opportunities. The WGS payload. An artists illustration of the Wideband Global Satellite Communications satellite WGS-11+. The contract was worth $160.3m and was extendible up to $1.3bn. The Option for WGS4 and 5 was exercised in November 2006. 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. Canada has also signed on to become a partner.[5]. Main; Satellites; TV Package; HD Channels; Ultra HD Channels; Coverage Maps; BISS key; Sat Receivers . The SATCOM Office provide SATCOM SystemExpert (SSE) support and functions to USSPACECOM and utilizes fourRegional SATCOM Support Centers (RSSCs) to provide global planning andoperational support to the various WGS user communities The military's Protected Tactical Waveform is expected to run on the WGS satellites. 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. 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). The Australian Government provided A$927m ($822.7m) in funding for ground infrastructure of the sixth WGS satellite under a memorandum of understanding (MoU) signed with the DoD in 2007. WGS 5 extended the Wideband Global SATCOM constellation to the Americas for a host of users following launch in May 2013. The very first Wideband Gapfiller in orbit will provide greater capability and bandwidth than all the DSCS satellites combined. Users of WGS include the U.S., Canada and Australia. A coverage footprint of 200-400 miles . Powered by EPSG database 10.076 The order for long lead items for WGS7 was placed in August 2010. Background It provides services to the US DoD and Australian Department of Defence. HOME / SATELLITES / Satellite Coverage Maps . The first WGS satellite was launched in 2007, with capability steadily improved such that WGS-10 can deliver download speeds of up to 11 gigabits per second. A satellite's latitude () is the latitude of the point These satellites have a much smaller coverage fraction f than does GPS, typically limited by a sensor's field of view. Telemetry and command links are available via X- and Ka-Band. In return, the Australian Defence Ministry was given access to the data sent by the sixth satellite, which was developed to increase the bandwidth capacity of US forces. The satellite operators come under the control segment. Leveraging the Space and Missile Systems Center's cross-corps enterprise structure, the three-day event was co-chaired by SMC . WGS-10 (USA-291) was launched atop a Delta IV Medium+ (5,4) launch vehicle from Cape Canaveral Air Force Station on 16 March 2019, at 02:26 UTC. The ground segment is a critical part of the end-to-end science data return, and it includes all the ground-based elements that are used to collect and disseminate information from the satellite to the user (figure 11.1).
