The International Wideband Global SATCOM (WGS) Program

The US military needs a bigger data firehose. In an era of streaming data from proliferating UAVs and other persistent surveillance platforms, and the need for control of those systems anywhere in the world, bandwidth is almost as important as fuel. Commercial satellite communications (SATCOM) can fill some of the gaps, but it’s expensive, and may not be available when needed. The Wideband Gapfiller SATCOM (now Wideband Global SATCOM) program began as a way to ease these problems in the near term, but went on to become one of the twin pillars of US military communications, alongside the hardened AEHF constellation. Both satellite types expanded their roles after the super-high bandwidth T-SAT program was canceled. instead, the USA is adding WGS and AEHF satellites in space, even as it makes both programs multi-national efforts here on earth.

WGS is a set of 13-kilowatt spacecraft based upon Boeing’s model 702 commercial satellite. These satellites will handle a significant portion of the USA’s warfighting bandwidth requirements, supporting tactical C4ISR (command, control, communications, and computers; intelligence, surveillance, and reconnaissance); battle management; and combat support needs. Upon its 2007 launch into geosynchronous orbit, WGS Flight 1 became the U.S. Department of Defense’s highest capacity communication satellite. WGS F4, launched in January 2012, offers further improvements, and the constellation is set to grow to 10.

This is DID’s FOCUS Article covering the WGS program’s specifications, budgets, travails, international partnerships, and contracts, with links to additional research materials.

The WGS constellation has limitations, as its wideband communications are “unprotected” against jamming and nuclear effects. This makes them less secure than programs like AEHF or the canceled T-SAT. On the other hand, WGS excels in 3 areas: bandwidth, coverage, and flexibility.

Each WGS satellite can route 2.1 to 3.6 Gbps of data, depending on the exact equipment and network settings – more than 10 times the communications capacity of the predecessor DSCS III satellite’s 0.25 Gbps. Indeed, One WGS satellite provides more throughput than the entire Defense Service Communications Satellite (DSCS) constellation did before WGS F1 was launched.

Using reconfigurable antennas and a digital channelizer, WGS also offers added flexibility to tailor its coverage areas, and to connect X-band and Ka-band users anywhere within the satellite’s field of view. The WGS design includes 19 independent coverage areas that can be positioned throughout the field of view of each satellite. This includes 8 steerable and shapeable X-band beams formed by separate transmit and receive phased arrays; 10 Ka-band beams served by independently steerable, diplexed antennas, including 3 with selectable RF polarization; and transmit/receive X-band Earth coverage beams. Within those limits, WGS’ digital channelizer divides the uplink bandwidth into nearly 1,900 independently routable 2.6 MHz subchannels, providing connectivity from any uplink coverage area to any downlink coverage area (including the X and Ka band crossbanding). The channelizer supports multicast and broadcast services, and provides uplink spectrum monitoring to support network control. Boeing adds that:

“Despite all of its military features, WGS is substantially more cost-effective than leased commercial SATCOM bandwidth.”

It is also more flexible. Unlike commercial service, WGS satellites can be repositioned in orbit to adapt to changing mission requirements.

WGS-4 and the Block II set will be similar to the 3 Block I satellites, but will include a switchable radio frequency bypass capability designed to support airborne intelligence, surveillance and reconnaissance platforms requiring additional bandwidth. The RF bypass will support data rates of up to 311 megabits per second, which is about 3x the rate of Block I birds, allowing platforms like the US Navy’s RQ-4N BAMS UAVs to rely on the WGS constellation for satellite control.

The U.S. MILSATCOM Joint Program Office (MJPO), Space and Missile Systems Center (SMC), is responsible for development, acquisition and sustainment of the WGS Program, which is a joint-service program funded by the US Air Force and Army. A total of 8 satellites are currently planned, augmenting X-band communications now provided by the Defense Satellite Communications System (DSCS) and one-way Ka-band service provided by the Global Broadcast Service (GBS). Additionally, WGS will provide a new 2-way Ka-band service.

Operation of WGS is a shared responsibility. Spacecraft platform control is accomplished by the 3rd Space Operations Squadron (3 SOPS) at Schriever AFB in Colorado Springs, CO, using WGS mission unique software and databases provided by Boeing, and hosted on the Command and Control Segment Consolidated (CCS-C) system fielded by Integral Systems, Inc. The satellite is designed for compatibility with current S-band capabilities, as well as the planned Unified S-band (USB) formats and frequencies. The Army controls the communications payloads and warfighter transmissions from 4 Wideband SATCOM Operations Centers (WSOCs) around the world, using ground equipment hardware and software developed by Boeing, ITT Industries, and Raytheon. Each Gapfiller Satellite Configuration and Control Element (GSCCE) has the capability to control up to 3 satellites at a time, via “in-band” (X-band or Ka-band) telemetry and command links.

The WGS Program & Schedule

The T-SAT Transformational Satellite Network that was originally intended to replace WGS, has been canceled. To address that gap, the US Department of Defense is buying AEHF-4 and 5 for secure communications, and WGS satellites 4, 5, 7, and 8 to augment and eventually replace existing DSCS satellites. The program has also become international. Australia bought WGS F6, and an international consortium led by Canada funded WGS F9. Full members now include the USA, Australia, Canada, Denmark, the Netherlands, and New Zealand, all of whom have seats on a WGS partnership steering committee.

The first Wideband Global SATCOM was originally scheduled to be launched in 2004, to be followed by 2 more satellites launched on Delta IV and Atlas V Evolved Expendable Launch Vehicle (EELV) rockets. That schedule was pushed back to launch in 2007, with F2 also intended to go aloft in 2007, and F3 scheduled for 2008. WGS F1 actually launched in October 2007, but was not declared operational until April 2008. WGS F2 launched in April 2009. WGS F3 had its schedule moved back several times; it was eventually launched in December 2009, and was declared operational in March 2010.

The Block II contract called for the launch of F4 by the first quarter of 2011, and subsequent launches of F5 and F6 in 2012 and 2013 (moving the launch schedules back by about a year). In reality, F4 looks set to launch in January 2012.

Budgets & Participants

As one might guess, the program’s budget has grown as well. WGS was originally envisaged as a US-only program, with an upper limit of $1.3 billion for 6 satellites. Though the program received the Air Force’s John J. Welch Award for acquisition management in 2001 for its use of commercial approaches, and stands well below program costs of $5 billion for its AEHF successor, total program cost rose beyond $1.8 billion, and the first launch was pushed back almost 3 years. That new $1.8 billion total included associated ground-based payload command and control systems, mission unique software and databases, satellite simulators, logistics support and operator training.

The WGS program’s design, integration and manufacturing issues stemmed from a number of causes. One was less-than-anticipated commercial demand for the commercial 702 satellite, which reduced the program’s expected ability to leverage commercial expertise and orders. A second problem arose after a launch date in December 2005 was scratched, in favor of a higher priority satellite. The delay was actually very fortunate, as subsequent checks found a widespread problem with fasteners in the satellite. That manufacturing issue caused heavy slippage in the satellite’s launch date, and created an expensive production gap between satellites F3 and F4.

By the time December 2009 arrived, program cost in comparable $FY01 was $2.971 billion for 7 satellites. The April 2010 SAR wording and FY 2011 budget included an 8th satellite, which seems like a discrepancy. The answer is that Australia’s purchase of F6, and international funding of F9, means that official American figures used for total program costs are based on only 7 birds. By August 2011, the 8th satellite was under contract, and a 9th WGS satellite was under consideration. By January 2012, the 9th satellite was under contract, and the program had 5 new countries as members.

According to US DoD documents, recent budget allocations to the program have included:

• FY 2006: $164.3 million: $92.3M RDT&E, $72M procurement.
• FY 2007: $452.1 million: $37.7M RDT&E, $414.4M procurement incl. WGS F4.
• FY 2008: $333.3 million: $21.0M RDT&E, $312.3M procurement.
• FY 2009: $81.1 million: $29.5M RDT&E, $51.6M procurement.
• FY 2010: $279.6 million: $67.2M RDT&E, $212.4M procurement. Funds on-orbit testing of F2 & F3, continues production of F4-F5, and Australia’s F6.
• FY 2011: $619.5 million: $60.2M RDT&E, $559.3M procurement incl. integration & test of F4 & F5, procurement of F7, and long-lead parts for F8.
• FY 2012: $792.9 million, all procurement, incl. production of F8.
• FY 2013 Request: $36.8 million, all procurement, funds only WGS checkout, launch and support costs.

WGS Industrial Team

As the prime contractor and overall systems integrator, Boeing supplies the satellites, and also performs final satellite processing and preparations for launch, as well as initial orbital operations and on-orbit testing. Listed members of Boeing’s WGS team have included:

• Harris Corporation in Palm Bay, FL. A major provider of radio communications systems, and will provide the satellite Ka-band antenna subsystem. They are also on the team as a leading provider of wideband satellite communications ground terminals, and for their expertise in terminal and payload interfaces.

• ITT Industries in Colorado Springs, CO. A top supplier of wideband satellite communications network management and control systems. They are integrating the payload control segment.

• Logicon has expertise in satellite communications network management software development and operations, and was originally leading the effort in system security engineering.

• Northrop Grumman Information Technology in San Pedro, CA was listed as leading the effort in system security engineering in releases from 2002 onward.

• Raytheon in Aurora, CO. contributing expertise in the control segments, along with ITT.

• SAIC contributes their depth of expertise in satellite communications systems engineering and communications architectures.

• Spectrolab in Sylmar, CA

• Universal Space Network (USN). Their network of ground stations in Hawaii, Alaska and a collaborative station in Italy play crucial roles during WGS transfer orbit operations and initial on-orbit testing.

The internationalization of WGS is likely to add suppliers from those countries as well, in accordance with local industrial offset agreements.

WGS Program: Contracts & Key Events

WGS-4, pre-launch
(click to view full)

April 12/12: Boeing announces that the USAF has accepted control of WGS F4, after several weeks of rigorous on-orbit tests from Boeing’s Mission Control Center in El Segundo, CA, and from “government facilities in central California.” Air Force operations personnel at Schriever AFB, CO are conducting additional tests, and preparing to move WGS-4 into its operational position so it can go into service this summer.

Jan 19/12: F4 launch. The 1st Block II satellite, WGS-4, successfully blasts off from Cape Canaveral aboard a Delta IV Medium-plus. It then sends signals from space, indicating readiness for on-orbit testing. So far, WGS 1 & 2 have launched on Atlas V EELV rockets, while 3 & 4 launched on Delta IVs.

WGS-4 used a ULA single common booster core powered by a Pratt & Whitney Rocketdyne RS-68 main engine, along with 4 ATK GEM 60 solid rocket motors. The 5m diameter upper stage was powered by a PWR RL10B-2 engine, with the satellite encapsulated in a 5m diameter composite payload fairing. ULA | Boeing | Boeing post-launch | ATK | America Space.

Jan 17/12: WGS International. At the Canadian Embassy press conference in Washington, USAF deputy undersecretary for international affairs Heidi Grant announces that Canada won’t be alone. All together, Canada, Denmark, Luxembourg, the Netherlands and New Zealand have agreed to contribute $620 million toward development of a 9th WGS satellite, in return for access to the system.

As noted below, Canada is investing the lion’s share, at $333 million. New Zealand is investing NZ$ 83.2 million [$66.5 million] over 20 years, which compares favorably to the current model of $NZ 4.3m per year, growing at about 10% per year, for 1/20th of the bandwidth. Australia’s experience has shown (vid. Aug 30/11 entry) that participation in WGS also entails changes to ground and receiving infrastructure. The Canadian Forces are defining requirements and preparing a separate tender for that, and the other countries involved will be doing likewise.

American officials said that they are open to negotiating the entry of new members, but said there were no specific expansion plans at the moment. USAF | New Zealand government | NextGov | Reuters | TMCNet.

Jan 17/12: Canada joins. Canada announces that it’s joining the WGS program, which will be known to DND as the Mercury Global project. DND currently pays about C$ 25 million per year to commercial providers, and was expecting those costs to rise over the next 20 years. As battlefield bandwidth demands continue to grow, it remains to be seen whether WGS will be able to serve as a full substitute for commercial providers.

“By signing the WGS Memorandum of Understanding, Canada joins allies such as Australia, Denmark, Luxembourg, the Netherlands, New Zealand, and the United States. In exchange for a contribution of [C$] 337.3 million [DID: about $333 million], the CF will obtain approximately 20 years of access to reserved frequencies for military communications systems in theatres of operation across the globe. This cost is approximately [C$] 140 million less than what was approved by the Order in Council in October 2011…. The signing of the MOU will provide funding for the construction of a ninth satellite.”

Canada’s IRB industrial offsets policy applies to this buy, but it’s a bit more complicated than usual. Boeing, Canada’s largest aerospace firm, must place activities in Canada equal to the standard 100% of Boeing’s C$ 240 million share. Since the WGS agreement was a direct government-to-government MoU, the Boeing agreement is a separate document. That document also commits Boeing to provide 20% of that C$ 240 million in “direct and/or global value chain business activities” involving Canada’s space sector, and a possibly-overlapping 10% with Canadian small and medium-sized businesses. Canada DND.

Jan 12/12: F9 contract. Boeing Satellite Systems, Inc. in El Segundo, CA receives a $376.5 million firm-fixed-price contract modification of the Wideband Global SATCOM (WGS) Block II follow-on contract, exercising the option to produce, process, launch, and activate on-orbit WGS F9. Per the pattern for WGS F8 (vid. Dec 16/11), it’s part of the $1.1 billion maximum contract announced on Sept 1/11, rather than being extra monies on top of that figure. Later events reveal that most of the satellite’s cost is paid for by Canada.

Work will be performed in Fort Worth, TX, and is expected to be complete by May 2013. The USAF SMC/PKJW in El Segundo, CA manages the contract (FA8808-10-C-001, PO 0020).

Dec 30/11: Boeing Satellite Systems in El Segundo, CA, is being awarded a $9.5 million cost-plus-fixed-fee contract modification. It pays for a study around upgrading the Wideband Global SATCOM Block II’s digital channelizer, as part of ongoing modernizations. This is normal for very expensive platforms that take a long time to build. Just because 2 satellites are “Block II” doesn’t always mean they’re the same, just as 2 Nimitz Class aircraft carriers can be very different under the skin.

Work will be performed in El Segundo, CA, and is expected to be complete on Jan 1/12 – which implies that the study is already done. the USAF SMC/PKJW in El Segundo, CA manages the contract (FA8808-10-C-0001, PO 0021).

Dec 16/11: F8 contract. Boeing Satellite Systems in El Segundo, CA receives a $296.1 million firm-fixed-price contract modification for WGS F8, as part of the Block II satellite follow-on. “The contract exercises the option to produce, process, launch, and activate on-orbit Satellite Vehicle Eight as previously negotiated.” Work will be performed in El Segundo, CA, and is expected to be complete by July 31/16. This was a sole-source acquisition by SMC/PKJW in El Segundo, CA (FA8808-10-C-001, PO 0018). See also USAF.

When queried, Boeing spokespeople explained that:

“Today’s authorization is one of those options on the [Sept 1/11] contract [clarified: and is part of that announced $1.1 billion rather than an addition to it].... The Block II satellites features a switchable radio frequency bypass that enables the transmission of airborne intelligence, surveillance and reconnaissance imagery at data rates approximately three times greater than the rates available on Block I satellites.”

Dec 15/11: Engineers complete the Delta IV rocket encapsulation procedure for WGS F4, at the Astrotech Space Operations facility in Titusville, FL. The event marks completion of Air Force Satellite Control Network compatibility testing, payload and bus functional testing and propellant load. The launch is scheduled for Jan 19/12, which is about a year after the original plan. USAF.

Dec 7/11: ITT Systems Corp. in Colorado Springs, CO won a $121.3 million multi-year, cost-plus-fixed-fee contract “for the services in support of the [WGS] missions identified in the Operational Management System.

Work will be performed in Colorado Springs, CO; Fort Meade, MD; Fort Detrick, MD; Wahiawa, Hawaii; Landstuhl, Germany; Okinawa, Japan; Fort Gordon, GA; MacDill Air Force Base, FL; and Canberra, Australia, and will run until Jan 31/19. The bid was solicited through the Internet, with 3 bids received by the US Army Space and Missile Defense Command at Peterson AFB, CO (W91260-12-C-0001).

Nov 28/11: United Launch Services, L.L.C. in Littleton, CO receives a $150 million unfinalized firm-fixed-price contract, for launch services in support of WGS F5, using their roster of EELV rockets. WGS uses the medium-heavy lift Delta IV or Atlas V. The USAF Space and Missile Systems Center in El Segundo, CA manages the contract (FA8811-11-C-0001).

Nov 17/11: Boeing begins shipping WGS-4 to Cape Canaveral, FL, in preparation for a January 2012 launch. The first Block II WGS satellite flew to Florida aboard a C-5 transport plane.

Oct 28/11: Canada, eh? Canada could also be set to join WGS, and may spend as much as $477 million to participate. The Conservative majority government has given Cabinet approval up to that sum, which means it’s a done deal if it stays within those costs. DND spokesman Daniel Bouin:

“After Afghanistan and Libya, our efforts in those two countries have proven that the exchange of information between headquarters and deployed elements is critical to modern military operations and their success. So, in order to meet that intent while ensuring good value for taxpayer money, we’re seeking out an agreement with international allies that will provide Canadian forces with access to an international constellation of satellites.”

U.S. deputy assistant secretary of defense for space policy, Gregory Schulte, reportedly said on Oct 4/11 that the USAF was in the final phases of developing similar WGS arrangements with several other allies. Canada is also looking to field a 2-satellite “Polar Communications and Weather Mission” constellation of their own, to cover the High Arctic where WGS doesn’t reach. Canada’s Postmedia | Satellite Today.

Oct 11/11: More countries in? Reports surface that The Netherlands is one of several US allies getting ready to join the WGS program, in order to provide more bandwidth for their military forces. By 2018, the WGS program could have 9 satellites in orbit to provide global coverage, serving the USA, Australia, Canada, Denmark, Luxembourg and New Zealand. Aviation Week | Defense Systems.

Sept 1/11: F7-F9 umbrella. Boeing Satellite Systems, Inc. of El Segundo, CA receives a maximum $1.1 billion firm-fixed-price contract modification to allow production of WGS Satellite Vehicle F7 (See also Aug 19/10 entry), as well as advance procurement for Satellite Vehicle F8, per the program changes announced in the April 1/10 Selected Acquisitions Report. Finally, this contract includes options to produce, process, and launch and activate F8 and F9 on-orbit. The SMC/PKJW in El Segundo, CA issued the contract (FA8808-10-C-0001, PO 0006). See also USAF | Boeing.

Aug 30/11: Australian ancillaries. The Australian Government agrees to first pass approval for Joint Project 2008 Phase 5B, which will buy transportable land terminals to equip the Army, upgrades of the satellite communications fit on Royal Australian Navy platforms, and the establishment of a satellite communications network management system.

The total cost of Joint Project 2008 Phase 5B is cost capped between A$ 300-500 million (currently $320-535 million) in the Public Defence Capability Plan. Initial funding of A$ 12 million has been approved for project development and risk mitigation studies, which must happen between 1st and 2nd pass approval. Studies will include the potential upgrade of the Geraldton ground station, and construction of a new ground station facility in Eastern Australia. Australian DoD.

April 20/11: The USAF says that WGS is proving very helpful in coordinating post-tsunami Japan relief efforts. Ka-band is reserved for emergency use in Japan, and such satellite signals are not allowed. Instead, they’re using WGS X-band transmissions, and using the satellite’s crosslinking capability to transmit to Ka-band receivers outside the region.

Dec 8/10: Boeing Satellite Systems Inc. in El Segundo, CA receives a $6 million contract modification to purchase a spare battery for WGS Block II satellites 5 & 6, or as a test battery for the Block II follow on contract, depending on things like satellites meeting launch schedules, discovering anomalies that would require a battery swap-out, etc. At this time, the entire amount has been committed by the SMC/PKJ at Los Angeles AFB, CA (FA8808-06-C-0001; P00094).

Dec 8/10: Boeing Satellite Systems Inc. in El Segundo, CA received a $26.4 million contract modification, exercising the option for WGS-6 launch services. This option modification is fully funded by the Australian government., and the entire amount has been committed. The SMC/MC in El Segundo, CA manages the contract (FA8808-06-C-0001; P00109).

Aug 19/10: F7 lead-in. Boeing Satellite Systems in El Segundo, CA receives a $182.2 million contract “which will provide the necessary items to begin production of Wideband Global SATCOM Satellite 7.” At this time, $164.4 million has been committed by the MCSW/PK at Los Angeles Air Force Base, CA (FA8808-10-C-0001). See also Reuters.

Aug 2/10: WGS Block I on-station. WGS-3 enters formal service with the U.S. Air Force. The first 2 WGS satellites are operating over the Pacific Ocean and Middle East, respectively, while WGS-3 is located over the Atlantic Ocean. This completes the WGS Block I network. Boeing | SatNews Daily | StrategyPage.

June 25/10: Boeing Satellite Systems, Inc. in El Segundo, CA receives a $6.8 million contract modification, which pays for additional on-ground testing thermal vacuum tests of the first WGS Block II satellite, SV4. At this time, the entire amount has been committed by HQ SMC/MCSW/PK in El Segundo, CA (FA8808-06-C-0001/ P00090).

June 25/10: The USAF announces that U.S. Strategic Command has accepted operational command and control of WGS-3.

WGS-3 is operated by the 3rd Space Operations Squadron at the 50th Space Wing in Schriever Air Force Base, CO. It’s under the operational command of the Joint Forces Component Commander for Space at Vandenberg Air Force Base, CA, where the JFCC SPACE Joint Space Operations Center continuously monitors WGS-3’s orbital safety and operational status.

May 25/10: Northrop Grumman announces the last flight test of the 1st airborne Ka-based satellite terminal for use with the WGS system. The flight test used the communications terminal system installed on a modified business jet aircraft to connect with a WGS via the Ka-band link. The test is the 2nd of 3 phases required to certify the airborne communications system for WGS operations. Northrop Grumman is performing the certification under the Multi-Role Tactical Common Data Link (MR-TCDL) Developmental and Operational Test program contract.

April 1/10: The Pentagon releases its April 2010 Selected Acquisitions Report, covering major program changes up to December 2009. WGS qualifies as a full breach under Nunn-McCurdy Legislation, as the program rises to 8 satellites and deals with its issues:

“WGS (Wideband Global Satellite Communications) – The APUC (Average Procurement Unit Cost) increased 27.2% to the current APB and 39.5% to the original APB. The original WGS acquisition strategy, approved in June 2000, called for a commercial-like Firm Fixed Price (FFP) competitively awarded contract with options for six satellites. The original program was baselined for 3 satellites assuming commercial pricing. At the time of the original WGS 1-6 contract award, a strong commercial market for wideband communication satellites was expected. Production options for WGS 1-3 were exercised, and the first satellite launched on October 10, 2007. Due to limited resources and other priorities, the contract options for satellites 4-6 were not exercised before they expired.

Subsequent decisions resulted in the department deciding to award another contract for WGS 4-6 Advanced Procurement and Production. A production break of approximately three years was introduced between WGS 3 and WGS 4. Further, following the acquisition of WGS 1-3, the commercial communication satellite market took a significant downturn, and the WGS X-band phased array transmit and receive system and digital channelizer capability were no longer available commercially. More recently, the department directed the procurement of additional satellite vehicles to support and maintain an eight satellite constellation. These satellites will follow a second break in production estimated at two years which will require re-establishing the supplier and contractor base and addressing issues with parts obsolescence.”

Officially, the accompanying PDF table lists WGS as having only 7 satellites, even though the test (and US FY 2011 budget documents) says 8. Total cost is now pegged at $2.971 billion in $FY01, or $3.441 billion in “then year” dollars (expected dollars actually paid, including inflation).

March 1/10: The USAF accepts control of the 3rd WGS satellite, after the satellite passed several weeks of on-orbit tests. WGS-3 completes the initial WGS constellation, and will be followed by 3 more WGS satellites under Block II of its USAF contract. Boeing release

Jan 29/10: Boeing Satellite Systems in El Segundo, CA received a $21 million change order to the Wideband Global Satellite Communications (WGS) program to integrate, test, and store the 1.5 ship-sets of xenon-ion propulsion system (XIPS) hardware procured. The XIPS is used to maneuver the satellite into its orbit and to change the satellite’s location if necessary. At this time, $14 million has been obligated. MCSW/PKW in El Segundo, CA manages the contract (FA8808-06-C-0001, P00070).

December 2009: Boeing integrates the WGS-4 payload module with a high-power Boeing 702 platform at the company’s Satellite Development Center in El Segundo, CA. WGS-4 is the first of 3 satellites to be built under the Block II contract, adding features like a radio frequency bypass designed to support airborne intelligence, surveillance and reconnaissance platforms requiring additional bandwidth. Over the next few months, the WGS team will conduct final integration activities followed by rigorous environmental testing, including vibration and thermal-vacuum tests.

WGS-1 and WGS-2, launched in October 2007 and April 2009, are already in service. WGS-3 was launched in December 2009. Boeing release.

Dec 5/09: F3 launch. After a Dec 2/09 launch was canceled for inclement weather and a Dec 3/09 launch was scrubbed due to a ground system fault, a United Launch Alliance Delta IV rocket lifted off from its Cape Canaveral Space Launch Complex-37 launch pad at 8:47 p.m. EST, with WGS-3 on board. It was the 36th successful ULA mission in 36 months. Boeing later reported that the satellite had checked out, and sent the first signals from space. Following a series of orbital maneuvers and on-orbit tests over the West Coast of the United States, WGS-3 will be placed into geosynchronous Earth orbit over the Atlantic Ocean.

The satellite joins WGS-1, which entered service over the Pacific Ocean in April 2008, and WGS-2, which began operations over the Middle East in August 2009. Both had been launched by the ULA’s Atlas V rockets. NASA Spaceflight mission overview | ULA Mission Overview [PDF] | Boeing.

Oct 10/07: F1 launch. WGS-1 is successfully launched at 8:22 p.m. Eastern (ZULU -0500) by a United Launch Alliance Atlas V vehicle from Cape Canaveral Air Force Base, FL. Following a nominal 45-minute flight, the launch vehicle’s upper stage deployed the spacecraft, and a ground station in Dongara, Australia received the satellite’s first signals 47 minutes later at 9:09 p.m. Eastern. Boeing controllers in El Segundo, CA confirmed that the satellite is healthy, and the firm has acquired signals from the first Wideband Global SATCOM (WGS) satellite. Boeing release.

Oct 3/07: Australia. Australia’s Minister for Defence announces that the Australian Government will enter into an A$ 927 million partnership (about $820 million) with the United States to become part of the new Wideband Global Satellite Communications (WGS) constellation. Dr. Brendan Nelson says that “I expect to finalise the arrangement through the signing of a government-to-government Memorandum of Understanding shortly after the 30 day US Congressional Notification Period.”

Under this arrangement, Australia will fund one satellite plus associated ground infrastructure, extending the constellation to 6 satellites. In return, they will receive global coverage from WGS, which will become the backbone of their military satellite communications capability. Minister Nelson’s release states that WGS “will comfortably handle the increase in ADF communications requirements… out to at least 2024.”

Achieving full operational WGS capability by 2013 will coincide with the predicted capability drawdown of the SingTel/Optus C1 satellite. The SingTel/Optus C1 satellite will remain an important element of Australia’s satellite capability until it fails, and will be maintained in parallel with WGS. DoD Ministerial release.
