Don’t Touch Their Junk: USAF’s SSA Tracking Space Debris
March 12/14: Sharing. Breaking Defense tweet:
“As of January, US, France are sharing space situational awareness data after half decade of talks. Also sharing w Aussies, Italy Canada Japan”
Waiting for that April 2014 Space Fence contract (q.v. Nov 21/13)…
Space is big. Objects in space are very dangerous to each other. Countries that intend to launch objects into space need to know what’s out there, in order to avoid disasters like the 2009 collision of 2 orbital satellites. All they need to do is track many thousands of man-made space objects, traveling at about 9 times the speed of a bullet, and residing in a search area that’s 220,000 times the volume of Earth’s oceans.
The US Air Force Materiel Command’s Electronic Systems Center at Hanscom Air Force Base in Massachusetts leads the USA’s Space Fence project. It’s intended to improve space situational awareness by tracking more and smaller objects, while replacing legacy systems in the Space Surveillance Network (SSN) as they retire. With a total anticipated value of around $6.1 billion over its lifetime, Space Fence will deliver a system of 2-3 geographically dispersed ground-based radars to provide timely assessment of space objects, events, and debris. International cooperation will supplement it, as part of overall Space Situational Awareness efforts. Failure is not an option. Or is it?
The current space fence has been operational since 1961, and Secure World Foundation technical advisor Brian Weeden charts at least 9 known collisions involving non-secret satellites. Meanwhile, the number of potential hazards is rising. In 1980, there were 5,396 total objects to track. In 2010, there were 15,639. Space Fence is expected to grow that set very quickly, because the higher wave frequency of the new Space Fence radars will let it detect much smaller microsatellites and debris than current systems. At the same time, global political and technology trends are accelerating the absolute number of these objects in space.
The Space Fence program will provide a radar system operating in the S-band frequency range to replace the Air Force Space Surveillance System (AFSSS) VHF “Fence” radar that currently performs detection of orbiting space objects. The Space Fence will have a modern, net-centric architecture that is capable of detecting and effectively tracking much smaller objects in low/medium Earth orbit (LEO/MEO). It was slated to go live by 2015, but current GAO reports believe this will be 2017 at the earliest, and subsequent development are pushing it toward 2018 – 2020.
To fit this program into its larger context, the US GAO characterized 4 facets of space situational awareness (SSA), an umbrella term that includes but it not limited to tracking space debris:
1. Detect, Track, and Identify. The ability to discover, track, and differentiate among space objects. Space Fence will anchor this facet, but it won’t be the only asset used for this purpose.
2. Threat warning and Assessment. The ability to predict and differentiate among potential or actual attacks, space weather environment effects, and space system anomalies. Space Fence may be able to help with this task, but in a secondary way.
3. Intelligence characterization. The ability to determine performance and characteristics of current and future foreign space and counterspace system capabilities, as well as foreign adversary intentions. Better monitoring of space may help with intelligence collection, but in a tertiary way.
4. Data integration. The ability to correlate and integrate multisource data into a single common operational picture and enable dynamic decision making. Out of scope for Space Fence. The USA’s pending Joint Space Operations Center Mission System (JMS) will play a large role here, and must be ready, or the amount of data generated by the new radars will exceed the existing system’s capacity.
The Space Fence Program: Old and New
The in-place AFSSS was also known as a “fence” because several transmitters and receivers create a narrow, continent-wide planar energy field in space. There are currently 9 AFSSS sites (3 transmitter, 6 receiver), located on a path across the southern United States from Georgia to California, along the 33rd parallel. Energy emitted from the transmitter sites forms a fixed, very narrow, fan shaped beam in the north-south direction, extending across the continental United States in the east-west direction. One or more of the receiver sites receives energy reflected from objects penetrating the beam. The 3 transmitter sites were located at Jordan Lake, AL; Lake Kickapoo, TX; and Gila River, AZ. The 6 receivers were located at Tattnall, GA; Hawkinsville, GA; Silver Lake, MS; Red River, AR; Elephant Butte, NM; and San Diego, CA.
In 2013, every one of these locations was shut down. In exchange, the Perimeter Acquisition Radar Characterization System at Cavalier AFS, ND is being modified, and the space surveillance radar at Eglin AFB, FL becomes the sole space radar.
It’s estimated that this closure will remove about 40% of the current surveillance network’s observation capability, and all of its long distance capability out to about 24,000 km/ 14,900 miles. Note that the Geosynchronous Orbit (GEO) used by most military satellites is up at 22,000+ miles, where Space Fence doesn’t really reach. On the other hand, launches and subsequent satellite raisings have to get there. There are also important global systems like Iridium, and a number of intelligence satellites, that sit in lower orbits.
The new Space Fence system would begin to fix this problem, but it would keep the total number of sites low, at just 2 or 3. John Morse, Space Fence Program Manager, Lockheed Martin MS2 Radar Systems:
“The new Space Fence will be located in geographically dispersed areas to give us better coverage in the Southern Hemisphere in particular. It will also enhance the space situational awareness by being able to see smaller objects…Space Fence will be a system of systems that consists of 2 to 3 large S-band radars and those radars will join other sensors in the space surveillance network and provide space situational awareness to the Air Force…The scope of the Space Fence contract includes sensors, mission processing, data processing, facilities, and communications, the whole system requirement…In order to use the space domain, we need to have accurate space situational awareness…We need to know where things are so we can use space when and how we need to use it. So the military application can be summed as giving the Air Force enhanced space situational awareness.”
The Space Fence procurement is broken down into the following phases: Phase A, Preliminary Design Review, System Development, Deployment and Follow-on support. System development of the large S-band radar is scheduled to begin in June 2012, with the first Space Fence radar site providing initial operational capability by the end of fiscal year 2017, and the final site providing full capability after 2020.
Space Fence data will be fed to the Joint Space Operations Center (JSpOC) at Vandenberg AFB, CA. Data from the Space Fence radar will be integrated with other SSN data to provide a more comprehensive and integrated space picture.
Over the 2011-2015 period, the Pentagon expects about 66% of their $3.3 billion SSA investment to buy new sensors, about 21% on JMS for data integration, and the other 13% on extending the lives of current sensors, and other SSA-related programs.
At an estimated program cost of $6.1 billion over its lifetime, Space Fence will be the USAF’s largest single investment in SSA sensors. It will serve alongside new systems like the SSBS satellite, the pending ground-based RAIDRS electromagnetic interference detection system, and DARPA’s pending ground-based Space Surveillance Telescope. They’re designed to boost the existing Space Surveillance Network, which includes 29 ground-based Department of Defense (DOD) and privately/foreign owned radar and optical sensors, at 17 worldwide locations; plus a communications network, and primary and alternate operations centers for data processing. Most of the sensors are mechanical tracking, phased-array, and continuous-wave radars, but optical telescopes are also used.
Contracts and Key Events
Poor planning delivers delays; RFP seems to be on again; USAF exploring whether they can do more on the cheap.
Jan 9/14: NDPP. Lockheed Martin announces a $3.9 million contract from the USAF Life Cycle Management Center, to develop a Non-Traditional Data Pre-Processor (NDPP) under the Integrated Space Command and Control (ISC2) contract.
ISC2 is responsible for providing conclusive and timely air and missile warning information, and also provides space situational awareness via the Space Surveillance Network. The NDPP system is an expansion of the ISC2 space data server, and also extends the communications infrastructure so that the Joint Space Operations Center (JSpOC) at Vandenberg AFB, CA can use a wider variety of sensors to maintain and update their space object catalog. NDPP’s infrastructure includes multiple security levels, and it will offer a new channel for receiving space object data, as well as a new collection system. Sources: Lockheed Martin, “Lockheed Martin Awarded Contract to Make Non-Traditional Sensor and User Data Available for Space Situational Awareness”.
Dec 20/13: SBIR. The USAF launches a Small Business Innovation Research (SBIR) project to improve space surveillance out to geosynchronous equatorial orbits. The sensors would use a wide staring field of view to cover more than 1000 square degrees per hour at 45 degrees elevation, during “typical” sky conditions at AFRL’s Starfire Optical Range (SOR), Kirtland AFB, NM. The ultimate goal is a cheap system that costs $1 million or less per site, and is used as an early-stage sensor to detect dim objects and immediately queue high-resolution systems for a closer look.
That would be useful, given current weaknesses in space surveillance. It’s also difficult. The USAF hopes that rapidly growing “off-the-shelf” technology for data bus architectures, networking, and electro-optic sensors makes it feasible.
Phase I will provide a mathematical model for system design, which helps create simulation tools, and work on small-scale lab tests. Those tests feed back into the models and simulations, with the goal of creating a system design that demonstrates the potential to meet these challenges. Phase II would demonstrate these capabilities at SOR, and develop prototype control systems, reporting systems, and procedures. Phase III would fully develop an operational scaled system prototype that can be easily deployed to one of USSTRATCOM’s electro-optical surveillance sites. Sources: SBIR.gov, “AF141-016: Persistent Wide Field Space Surveillance.” | C4ISR & Networks, “USAF wants to detect dim space objects – cheaply”.
Nov 21/13: USAF Space Command commander Gen. William Shelton tells the AFA’s Pacific Air & Space Symposium in Los Angeles, CA that he’s aiming for an April 2014 contract:
“We have now been given the go-ahead to release that modified [Space Fence RFP] and begin our acquisition program again… Hopefully we’ll have that on contract in the April time frame, and that will represent about a one-year slip in the program because of the delay here, but nevertheless we’ll get a very good sensor that will help us keep track in a much-larger-volume sense and a much-better-resolution sense of the traffic in low Earth orbit.”
Extra points to the general for using the movie “Gravity” in his speech, as a way of highlighting why space situational awareness is important. Sources: Space News, “Pentagon Approves Latest Air Force Space Fence Plan”.
Oct 24/13: RSS RFP. The Air Force releases an RFP for a flexible coverage risk reduction study (RSS):
“Key among these unique capabilities is flexible coverage, which is a search mode of operation that enables coverage in various orbital regimes (altitudes) with enhanced sensitivity and variable search volume coverage modes to support operations like new object discovery at higher altitudes, proximity operations/neighborhood watch for space protection, etc. This capability enables the radar to schedule detection fences covering either a user-defined fixed region or a region defined in orbital space.”
They may award up to 2 Firm-Fixed-Price contracts for a maximum total of $9.9 million, with 5.5 months of anticipated work. A Notice of Proposed Contract Action released in September limits that RFP to incumbents Lockheed Martin and Raytheon. FA8709-13-R-0003.
Oct 23/13: Revised milestones. In their testimony [PDF] to the House Armed Services Subcommittee on Tactical Air and Land Forces, William A. LaPlante, Deputy Assistant Air Force Secretary for Acquisition, and USAF Deputy Chief of Staff Lieutenant General Michael R. Moeller, wrote:
“The Space Fence contract was ready for award in early June; however, a DoD-level review driven by sequestration, delayed the decision to proceed into later in 2013. With an affirmative decision in November, initial capability will slip about one year and costs will increase by over $70M.”
So “the Pentagon made me do it” is the Air Force’s posture on this (see also July 16/13). There is some truth to that narrative, since the Office of Management and Budget (OMB) and DoD explicitly instructed departments and agencies to ignore the Budget Control Act (BCA) until the last minute, following the universal Stuff Rolls DownHill (SRDH) principle. In any case, the anticipated date for Initial Operational Capability (IOC) was postponed in August by a year, after having already been moved from 2015 to 2017 a year ago. Presumably this also affects the Full Operational Capability (FOC) deadline, which had been set to 2020.
The ongoing Space Fence EMDPD RFP (q.v. Oct 4/12) is about to be amended, and an award is now planned for March 2014. Additionally, the Procuring Contracting Officer was changed in September.
FY 2012 – 2013
PDR; 1st site picked; RFP, bids; Shutdown of most existing sites – for what?
Aug 12-14/13: Space Fence Shutdown. So, the total amount of money saved by shutting down the Space Fence (AFSSS) by Oct 1/13, due to “resource constraints caused by sequestration”? $14 million per year. Instead, USAF SMC is looking at modifying operating modes for the Perimeter Acquisition Radar Characterization System at Cavalier AFS, ND and the space surveillance radar at Eglin AFB, FL. The USAF’s defense:
“The operational advantage of the AFSSS is its ability to detect objects in an un-cued fashion, rather than tracking objects based on previous information. The disadvantage is the inherent inaccuracy of the data, based on its dated design. The new operating modes at Cavalier AFS and Eglin AFB will provide more accuracy than the AFSSS and still collect un-cued observations.”
On the flip side, it’s worth asking what percentage reduction that represents for tracking coverage. Less coverage means that less debris will be tracked, which means less accurate orbits, which makes predicting collisions harder and less accurate. The new plan also leaves Eglin AFB as the only dedicated space radar, so it creates an absolute failure risk.
Meanwhile, the USAF throws critics a bone by touting the improved capabilities of the new Joint Space Operations Center’s high performance computing, and the new fence. Without committing to construction. While also suggesting that maybe others should just pick up the mission. USAF Gen. Shelton told Satellite Today that “other countries, as well as the commercial sector,” might try to offer capabilities of their own. The Europeans are moving in this direction, slowly, and Intelsat General’s Nancy Nolting says that their satellites could carry sensors to build a supplementary network in orbit. At the end of the day, however, someone has to pay for that. The question is now “whom?” Sources: USAF release | Satellite Today, “US Air Force Space Fence Shutdown Threatens Satellite, Aerospace Industries” | Space News, “U.S. Air Force: Space Fence Shutdown To Save $14 Million Annually”.
Aug 5/13: Over in Europe… A July 2013 proposal to the European Parliament, Council and other EU bodies, the EC would help EU nations fund development of a space surveillance and tracking (SST) network. It would be based on French & German radars and other systems, for about EUR 10 – 120 million per year. Candidate assets include the French Graves demonstration radar (range 1,000 km/ 620 miles), Germany’s TIRA (more powerful, but track just 1 object at a time), 3 Satam French air force tracking radars, the nascent Oscegeane telescope/ spectroscopy application, and the Fedome space weather system.
France is building out a Cosmos tracking center in Lyon by 2014, but still needs to develop a Space Information System. The German Space Situational Awareness Center (GSSAC) in Uedem, Germany is also ramping up, but isn’t expected to be really ready until 2020. Cooperation would be positive, especially if Graves could note objects and cue TIRA to identify them. Even so, the bottom line is that the systems’ limited range and breadth won’t replace resources like the US Space Fence, even at a regional level. Nor has the EU’s ESA been able to get very far with wider initiatives of its own. Aviation Week, “EU Aims For Space Situational Awareness Network”.
Aug 1/13: Space Fence Shutdown. A memo from USAF Space Command commander Gen. William Shelton tells Five Rivers Services of Colorado Springs, CO to prepare for shut-down at the current Space Fence system’s 3 transmitter and 6 receiving sites. The USAF has decided not to exercise the 5th option year of their support contract, and won’t be giving it to anyone else:
“A specific list of action items will be provided as soon as it is finalized. A specific date to turn off the mission system has not been established yet, but will be provided to you immediately upon determination.”
Technically, they’re deactivating 3 transmitters and 4 receiving sites. The 2 receiver sites at Tattnall, GA and Silver Lake, MS were deactivated in April 2013, as an automatic response to sequestration. It’s estimated that this full closure will remove about 40% of the current surveillance network’s observation capability, and all of its long distance capability out to about 24,000 km/ 14,900 miles. Note that the Geosynchronous Orbit (GEO) used by most military satellites is up at 22,000+ miles, where Space Fence doesn’t really reach. On the other hand, launches and subsequent satellite raisings have to get there. There are also important global systems like Iridium, and a number of intelligence satellites, that sit in lower orbits.
There’s a judgement call involved about the USAF’s intentions. Is this a serious response, or a classic bureaucratic “Washington Monument” exercise? For the uninitiated, a “Washington Monument” response does something that will cause the maximum amount of damage or inconvenience, blames it on “budget cuts” even if the amount saved is trivial, and tries to create a groundswell to reverse all of the cuts. A well functioning system would simply fire administrators who use this tactic, due to loss of confidence in their decision-making; but that requires intervention from outside the bureaucracy in question, and rarely happens. Space News, “Shelton Orders Shutdown of Space Fence”.
Existing AFSSS Space Fence to shut down
July 16/13: Why no contract? The USAF says they would have issued the Space Fence contract by now, but the Pentagon’s Strategic Choices and Management Review (SCMR) has put it on hold. SCMR is meant to look at how the US military would react if budget cuts aren’t reversed, with scenarios involving $100 billion, $300 billion and $500 billion in cuts over a 10-year period.
If the new Space Fence falls victim, there’s some discussion of upgrading space surveillance sensors already at Eglin AFB, FL, even though that won’t provide the same low-and-high-inclination orbit coverage, or address key back-end systems. USAF Space Command head Gen. William Shelton says that they’re also looking at “new architectures”, without specifying further. Aviation Week | Defense News.
June 21/13: Global Horizons Study. MITRE delivers the USAF’s Global Horizons study, which states:
“There are clear threats to the U.S. space enterprise, including growth in space debris, space weather induced upsets, the increasingly easy access to space, and potential cyber/EW (electric warfare)/kinetic attacks on our space and space-support ground assets…. Generally speaking, the U.S. has put a lot of eggs in very few baskets and when you look at the limited number of missile warning communication satellites, weather satellites and even NRO satellites, an aggressor could severely disable and even degrade U.S. capabilities with only a handful of successful shoot downs of U.S. satellites.”
Nov 14/12: Bids in. Raytheon and Lockheed Martin both announce that they have submitted their bids to finish development, and build the USA’s new Space Fence.

Sept 25/12: 1st site. The USAF has picked its 1st Space Fence radar site on Kwajalein Island in the Republic of the Marshall Islands, South Pacific. Construction of the S-band radar and buildings is expected to begin in September 2013, with 48 months planned to complete construction and testing, and Initial Operational Capability (IOC) planned for fiscal year 2017.
After IOC, the 21st Space Wing is expected to manage about 10-15 contractors as a long-term work force, and a Support Agreement will be established between USAF Space Command and the US Army Kwajalein Atoll/Reagan Test Site for site support and facilities maintenance. USAF.

March 21/12: GAO report. “DOD Faces Challenges in Fully Realizing Benefits of Satellite Acquisition Improvements” includes a discussion of Space Fence’s acquisition strategy, and potential pitfalls. The agency doesn’t believe Space Fence will be ready before 2017, and sees a strong technical risk if the accompanying JMS ground system isn’t ready at the same time:
“Space Fence program officials have stated that Space Fence will be one of the largest phased array radars ever built. The size of the radar is expected to provide significant power… but may also pose increased risk… To mitigate this risk, the Space Fence acquisition strategy includes maintaining competition through technology development and having two firms under contract doing parallel prototype development. This process allows program officials to evaluate contractor’s designs and associated costs while moving Space Fence’s four critical technologies and backup technologies toward maturity, before the program enters system development which is scheduled for later this year with the award of a single contract. Though earlier plans called for the first Space Fence site to achieve initial operational capability in 2015, estimates show that at current funding levels, this capability will not occur before 2017.
…Another area where synchronization in system development may pose problems is the Air Force’s Joint Space Operations Center Mission System (JMS) and Space Fence programs. JMS is to process data about space assets gathered by the Space Fence and other Space Situational Awareness (SSA) programs, and will increase DOD’s ability to track objects in space from about 10,000 objects with the current system to over 100,000 objects. According to the Space Fence program office, JMS needs to be available when the Space Fence is fielded because the amount of data Space Fence will generate exceeds existing command and control system performance limits. JMS recently underwent a change to its acquisition strategy, dividing the program’s development into two increments to reduce risk and more rapidly deliver needed capabilities. The first Space Fence radar site is scheduled to provide initial operational capability by the end of fiscal year 2017, and… JMS needs to be operational by this time.”

Phase A; preliminary design.
May 31/11: The US Congress’ Government Accountability Office auditors looks at American programs for monitoring space debris, and voice serious concerns. Excerpts:
“DOD has significantly increased its investment and planned investment in SSA acquisition efforts in recent years to address growing SSA capability shortfalls. Most efforts designed to meet these shortfalls have struggled with cost, schedule, and performance challenges and are rooted in systemic problems that most space acquisition programs have encountered over the past decade. Consequently, in the past 5 fiscal years, DOD has not delivered significant new SSA capabilities as originally expected… two critical acquisition efforts that are scheduled to begin development within the next 2 years – Space Fence and the Joint Space Operations Center Mission System (JMS) – face development challenges and risks, such as the use of immature technologies and planning to deliver all capabilities in a single, large increment, versus smaller and more manageable increments… GAO recommends that DOD assure–in approving the Space Fence and JMS acquisition efforts to initiate product development–that all critical technologies are identified and matured, and that other key risks have been fully assessed. If DOD determines that the programs should move forward with less mature technologies, DOD should assess available backup technologies and additional resources required to meet performance objectives…”
The GAO adds elsewhere that governance is at least as much of a problem as technology:
“There are significant inherent challenges to executing and overseeing the SSA mission, largely due to the sheer number of governmentwide organizations and assets involved… while the recently issued National Space Policy assigns SSA responsibility to the Secretary of Defense, the Secretary does not necessarily have the corresponding authority to execute this responsibility. However, actions, such as development of a national SSA architecture, are being taken that could help facilitate management and oversight governmentwide. The National Space Policy, which recognizes the importance of SSA, directs other positive steps, such as the determination of roles, missions, and responsibilities to manage national security space capabilities and the development of options for new measures for improving SSA capabilities… Finally, though the commercial sector and the international community are to play a pivotal role in the SSA mission, it is too early to tell whether DOD’s efforts to expand and make permanent its Commercial and Foreign Entities SSA data-sharing pilot program will be effective in integrating efforts to develop SSA capabilities.”
With respect to the Space Fence in particular, the report says that the original 3-site system (notionally Australia, Ascension Island in the south Atlantic, Kwajalein Atoll in the Marshall Islands) is very likely to devolve into a 2-site system on cost/benefit grounds, as the current Technology Development Phase assesses costs and tradeoffs. It adds:
“The primary program risk… is that the new Joint Space Operations Center Mission System (described below) will need to be available to process Space Fence data, as the amount of data provided will result in an increase in uncued detection and tracking capacity from 10,000 to 100,000 objects… other risks of the program include large-scale integration and calibration of radar arrays, scalability of the design for the digital beam former,[C] and development of information assurance certification criteria… All five critical Space Fence technologies identified by the program office are immature – one at technology readiness level (TRL) 4 and four at TRL 5… mature backup critical technologies exist which could be used… our best practices work has shown technology development to TRL 7 could significantly reduce risk to meeting cost, schedule and performance goals.”
Jan 26/11: Lockheed Martin and Raytheon each receive an 18-month contract worth $107 million (total: $214 million) for Space Fence Preliminary Design. These preliminary system designs must use mature technologies that meet or exceed Technology Readiness Level 6 and Manufacturing Readiness Level 6. The firms will also conduct radar performance analyses, evaluations and prototypes, and related activities, en route to a functional radar prototype with hardware and software components representative of the technology in the final design. A final production contract to one of the companies is expected in 2012.
Raytheon Integrated Defense Systems of Sudbury, MA will produce 1 preliminary design for the Space Fence Program. At this time, $20 million has been obligated by the ESC/HSIK at Hanscom AFB, MA (FA8707-11-C-0004),

“The Department of Defense has signed a Space Situational Awareness (SSA) international sharing agreement with the Department of Defence of Australia. This signed government-to-government memorandum is the first that will permit an advanced exchange of SSA data.”
See also Nov 15/12 entry. Australia was originally envisaged as a site for a 2nd new Space Fence location, but the USAF isn’t making any commitments. Meanwhile, this appears to be an extension beyond the November memorandum. Pentagon release.

Nov 27/12: GEODSS. GEODSS uses powerful telescopes, low-light cameras and computers to detect, track and report man-made deep space objects 3,000 or more miles from earth. BAE Systems has been supporting GEODSS since 2009, and announce a $5.5 million contract extension for FY 2013. The USAF’s 21st Space Wing, at Peterson AFB in Colorado Springs, CO manages this contract.
The GEODSS network is located at Maui, Hawaii; Socorro, NM; and the island of Diego Garcia in the Indian Ocean. Each site has 3 telescopes (2 x 40″/ 2 degree main and 1 auxiliary; Diego Garcia is 3 main) that operate at night and can detect objects 10,000 times dimmer than the human eye threshold. The telescopes move across the sky at the same rate as the stars appear to move, then use computer post-processing to eliminate star images. The resulting tracks are used to update the list of orbiting objects, and sent nearly instantaneously from the sites to Cheyenne Mountain AFB, CO. BAE Systems | FAS on GEODSS.
Nov 15/12: Australia. Australia and the USA sign a Memorandum of Understanding regarding space surveillance, building on the 2010 Australian-United States Space Situational Awareness Partnership Statement of Principles.
Under the agreement, they’ll establish a jointly-operated C-band radar space surveillance installation at the Harold E. Holt naval communication facility in Exmouth, Western Australia. The C-band radar facility will be operated by the Royal Australian Air Force on behalf of the United States. They’ll also work together to transfer a highly advanced space surveillance telescope to Australia. Its location and operating arrangements will be settled later. According to Australia’s DoD:
“The hosting of SSA facilities in Australia will improve the overall performance of the global network of sensors forming the US Space Surveillance Network, through which the US provides a warning service to all satellite operators, and publicly available information on the orbits of satellites and space debris. Addressing a gap in the Network’s coverage in the southern hemisphere will allow for more accurate tracking, and reduce the danger of accidental collisions between satellites and space debris.”

May 23/12: Canadian help. Canada’s Department of National Defence (DND) announces a long-term partnership with the Pentagon on Space Situational Awareness (SSA). Better yet, they’re offering concrete help, via a project worth “under [C$]100 million”.
Canada already helps the USA with space surveillance, through the joint use of some NORAD radars with a secondary space-tracking capability. Now, it’s going to add an optical satellite called Sapphire, whose data will be contributed to the U.S. Space Surveillance Network. Sapphire is scheduled for launch later in 2012, atop an Indian Polar Satellite Launch Vehicle (PSLV) from the Satish Dhawan Space Centre at Sriharikota, in southern India.
Adding optical, in-space collectors to the SSN is a good way to offset some of the Space Fence radar’s technical risk, but adding more data sources also means that breaking past the current limitations of the JMS ground system becomes even more important.
