Boeing gets $21 million contract to integrate, test, and store the 1.5 ship-sets of the WGS xenon-ion propulsion system. (Jan 29/10)

The WGS program is actually a set of 13-kilowatt spacecraft based upon Boeing’s model 702 commercial satellite. These satellites will support the USA’s warfighting bandwidth requirements, supporting tactical C4ISR (command, control, communications, and computers; intelligence, surveillance, and reconnaissance); battle management; and combat support needs. The program name has been changed for some reason from “Wideband Gapfiller Satellite” to “Wideband Global SATCOM,” presumably to avoid the (correct) suggestion that it fills an emerging gap. Readers should be aware that references to either title in documents, archives, or the media denote the same program.

Upon its first launch into geosynchronous orbit, WGS Flight 1 became the U.S. Department of Defense’s highest capacity communication satellite. This is DID’s FOCUS Article covering the WGS program…

WGS: Capabilities & Role

The T-SAT program faces ongoing and projected bandwidth shortfalls in an era of proliferating UAVs and other persistent surveillance platforms, and reliance on costly commercial SATCOM. The goal of the WGS program is to alleviate these issues in the near term, acting as a gap-filler based on an existing commercial design until programs like AEHF and eventually TSAT step in to provide further bandwidth expansions.

Each WGS satellite can route 2.4 to 3.6 Gbps of data – providing more than 10 times the communications capacity of the predecessor DSCS III satellite. Indeed, One WGS satellite will provide more throughput than the entire Defense Service Communications Satellite (DSCS) constellation currently on station. 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. Unlike programs like AEHF or T-SAT, however, WGS offers wideband communications that are “unprotected” against jamming and nuclear effects.

A 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 ability to cross-band between X and Ka frequencies). The channelizer supports multicast and broadcast services, and provides uplink spectrum monitoring to support network control. WGS-4 will be similar to the three Block I satellites, but will include a 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.

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. Up to 6 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 two-way Ka-band service.

Control is accomplished from 4 Army Wideband Satellite Operations Centers (WSOCs), using ground equipment hardware and software developed by Boeing, ITT Industries, and Raytheon Corp. Each Gapfiller Satellite Configuration and Control Element (GSCCE) has the capability to control up to three satellites at a time, via “in-band” (X-band or Ka-band) telemetry and command links. Spacecraft platform control is accomplished by the 3rd Space Operations Squadron (3 SOPS) at Schriever AFB in Colorado Springs, using WGS mission unique software and databases provided by Boeing, hosted on the Command and Control Segment Consolidated (CCS-C) systems that are being 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 T-SAT Transformational Satellite Network, although originally intended to replace WGS, has effectively been canceled. To address that gap, the US Department of Defense procured AEHF-4, and WGS satellites 4 and 5. Australia will be buying WGS-6, making WGS an international program.

The Block II satellites (F4-F6) will include enhanced capabilities, such as an RF bypass to support ultra-wide terminals needed for airborne Intelligence, Surveillance & Reconnaissance missions. The USA’s RQ-4N BAMS UAVs, for example, will rely on the WGS constellation for satellite control.

The WGS Program & Schedule

The WGS program was originally envisaged as having 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 has risen above $1.8 billion and the first launch has been pushed back almost 3 years. That new $1.8 billion total includes associated ground-based payload command and control systems, mission unique software and databases, satellite simulators, logistics support and operator training. Boeing also performs final satellite processing and preparations for launch, as well as initial orbital operations and on-orbit testing.

The WGS’ design, integration and manufacturing issues stem from a number of causes, but they are partly due to less-than-anticipated demand for the commercial 702 satellite, which reduced the program’s expected ability to leverage commercial expertise and orders. A launch date in December 2005 was scratched in favor of a higher priority satellite. That turned out to be a fortunate development, as it was followed by discovery of a widespread issue 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.

According to US DoD documents, The FY 2006 budget allocated $164.3 million to the WGS program: $72 million for procurement, and $92.3 million in R&D. The FY 2007 request for the program is $452.1 million: $414.4 million to procure satellite #4, and $37.7 million in R&D.

As the prime contractor and overall systems integrator, Boeing leads a team of companies. Listed members 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 will play crucial roles during WGS transfer orbit operations and initial on-orbit testing.

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 launched in October 2007, but was not declared operational until April 2008. WGS F2 launched in April 2009, and WGS F3 had its schedule moved back several times; it was eventually launched in December 2009.

The Block II contract calls 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). WGS will augment and eventually replace the DSCS currently on station.

(click to view full)

Oct 10/07: 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’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.

June 26/07: Integral Systems, Inc. in Lanham, MD received a $5.8 million cost-plus-award-fee contract modification. It modifies the Command and Control System-Consolidated (CCS-C) effort to support the Wideband Gapfiller Satellite (WGS) Program Operations Readiness, add training, and incorporate changes to the system/Subsystem Specification (SSS) to clarify development requirements for the Advanced Extremely High Frequency (AEHF) satellite program.
