First Civil Funds for GPS Program

FY09 GPS Budget Request; FAA Line Item

The GPS program has passed a milestone of sorts with the first allocation of funds from civil agencies to pay for a portion of the core GPS budget.

The Fiscal Year 2008 (FY08) budget for the U.S. Department of Transportation (DoT) sets aside $7.2 million as the first installment on the civil share of GPS modernization efforts, including the L1C signal that will be transmitted on the GPS Block III satellites and costs of monitoring the civil GPS signals in the modernized ground control segment (OCX). For the FY09 budget, the Bush administration has requested a $20.7 million allocation. The total five-year civil contribution (FY09-13) is expected to be more than $200 million.

Another Successful GPS Launch, Plan Produce Back-Up and Improved Capability

Successful launch of a GPS Block IIR satellite on March 15 continues a U. S. Air Force initiative to bolster the nation’s GNSS constellation against anticipated failures of aging on-orbit spacecraft while improving system accuracy and accelerating the availability of new military signals.

An analysis of the condition of subsystems on GPS satellites in orbit last year indicated that up to nine GPS space vehicles (SVs) could fail in the near future, according to Col. David Madden, commander of the GPS Wing at the Space & Missile Systems Center, Los Angeles Air Force Base, California. “That’s what drove us down this path of launching five in one year,” said in a recent news conference.

Europe Readies Galileo Procurement

Having transformed the Galileo program into a fully public procurement, European agencies have announced a schedule that would lead to contracts for the €3.4-billion project by the end of 2008. And non-European companies may be involved in providing certain components and services to the effort.

The plans were revealed in presentations by high-ranking figures from the European Commission (EC) and European Space Agency (ESA) speaking at the Munich Satellite Navigation Summit in Germany, February 19–21.

Having transformed the Galileo program into a fully public procurement, European agencies have announced a schedule that would lead to contracts for the €3.4-billion project by the end of 2008. And non-European companies may be involved in providing certain components and services to the effort.

The plans were revealed in presentations by high-ranking figures from the European Commission (EC) and European Space Agency (ESA) speaking at the Munich Satellite Navigation Summit in Germany, February 19–21.

In comments at the conference, Jacques Barrot, EC Vice President and commissioner for transport and energy, and Giuseppe Viriglio, ESA director of telecommunications and navigation, indicated that they hope to see invitations to tender (ITTs, essentially, requests for proposals) to be issued July 1.

Deadline for tenders would follow within a few months, followed by a review of bids and contract awards in December. Identification of prospective bidders and requests for information will precede the ITTs, activities that will probably begin within the next few weeks.

The EC and ESA still need to complete a “delegation agreement” that would outline the responsibilities and principles under which ESA would act as the prime contractor — the procurement agent and design authority that will oversee the engineering work and contracts under which the ground and space infrastructure would be built. It will receive an estimated €195 million for that role.

ESA will set up a new Galileo directorate, Viriglio said, to handle its responsibilities. The European Commission will act as the Galileo program manager, taking on additional staff to handle the work, according to Paul Verhoef, head of the Galileo Unit in the EC’s Directorate-General for Transportation and Energy. The ESA directorate would have about 30–40 staff members and the EC Galileo unit would gain about 35 persons to handle program management, according well-informed sources.

The procurement contract schedule will have to be met in order to have a chance to meet the goal of Galileo having a fully operational capability (FOC) by 2013.

The acquisition is divided into six “work packages”: system engineering support, completion of ground mission infrastructure, completion of ground control facilities, launchers, satellites (26 in batches of 10–12, 6–8, and 6–8), and operations.

No company or consortium of companies may bid for more than two of the six packages. The prime contractors must subcontract at least 40 percent of the work to companies not affiliated with them.

In the program’s clearest statement of interest in gaining from the GNSS-related experience of other countries, Viriglio underlined the possibility for European industries “to rely on non-European sources for certain components and services in case of demonstrated substantial advantages in terms of quality and costs, taking account of the strategic nature of the European GNSS programs and of the EU security and export control requirements.”

ESA Takes the IOV Reins. Meanwhile, ESA has already taken over as prime contractor for the in-orbit validation (IOV) phase of the program after a billion-euro contract with European Satellite Navigation Industries (ESNI) was terminated in December. IOV includes construction and launch of four full-fledged Galileo satellites in 2009–2010 to form a mini-constellation for additional validation testing before the other 26 spacecraft are launched in 2011–13.

All the other IOV contracts will be retained as will the associated technical baseline, said Viriglio. European officials still need to figure out how they will cover an estimated $350-million overrun in IOV caused by delays, unexpected security costs, a change in the Open Service signal design as a result of the 2004 EU-US agreement on interoperability of GPS and Galileo, and dependence on a single customer (ESNI).

European officials repeatedly emphasized that the €3.4 billion was the most that they would spend on implementing Galileo, and that competition for contracts would take place under European Union (EU) rules rather than ESA procurement policy, which allocates 90 percent of funds to businesses based on the contributions from the member states in which they are located.

The calculation of $3.4 billion is based on cost estimates by ESA, drawn primarily from industry proposals and earlier studies and concession negotiations under the Public Private Partnership (PPP) concept, which was discarded last year. The largest portion of the costs would be for the space segment — building and launching satellites — estimated at €1.6 billion; the ground segment, €400 million; operations, €275 million; and systems engineering support, €150 million.

Members of aerospace companies that will probably compete for the contracts were less optimistic in their estimates of whether $3.4 billion will be enough.

Galileo has one satellite in orbit, the so-called GIOVE-A, which launched in December 2005 and will reach the end of its design life in March, although its builder, Surrey Satellite Technology Ltd., predicts that it will continue operating at least through the end of 2008. A second, larger spacecraft, GIOVE-B, is now scheduled for launch on April 26 from the Baikonur space center in Kazakhstan.

More than €2.6 billion has been spent on Europe’s satellite navigation program to date, mostly by the EC and ESA. This includes €133 million for the definition phase, €1.5 billion for the IOV phase, €520 million for the European Geostationary Navigation Overlay Service (EGNOS), and €480 million for Galleo-related projects financed through the EU’s Framework R&D programs. EGNOS is a satellite-based augmentation system that will be integrated into the Galileo infrastructure and operations over the next few years.

Who Calls the Shots? A new regulation regarding financing, governing structure, and procurement procedures for Galileo will be taken up by the European Council in April. But now that the funding and acquisition process have been largely resolved, the outstanding issue facing the Galileo program is governance, that is, the matter of political direction and control of the system’s implementation.

Now that the funding and acquisition process have been addressed, the outstanding issue facing the Galileo program is governance, that is, the matter of political direction and control of the system’s implementation. That, in turn, will have a substantial effect on whether the program is able to stay on schedule and within budget.

Until the abandonment of the PPP, that issue had seemed fairly clear. The European GNSS Supervisory Authority (GSA), a Community agency with a executive board made up of directors from the EU member states, would sign and monitor a contract with a private consortium to build and operate Galileo under a 20-year concession.

Now, however, the GSA has lost that primary supervisory role and has come under pressure from both the EC and the European Parliament, which approved the €3.4-billion Galileo program budget last November.

The 2004 EC Council regulation that created the GSA also assigned it other responsibilities: market development of the Galileo operational phase, GNSS-related research, technical certification of the components and services of the Galileo system, management of Galileo security aspects, coordinating radio frequency activity, and managing the agreement with an EGNOS service provider.

The EC would clearly like to bring the GSA back under its direct control, either as a separate but subsidiary entity or by absorbing key technical staff members into the Galileo Unit headed by Verhoef. “What we need is the expertise of the GSA, either directly or through a transfer to an EC office,” Verhoef said at the Munich conference.

Two related approaches are now under consideration: retaining a GSA, separately or within the EC, and restructuring it as a GNSS Security Agency that would handle GNSS security issues and, perhaps, technical certification of the Galileo system being built under the supervision of ESA. ESA would take over most or all of the GSA’s technical responsibilities and the EC Galileo Unit, as program manager, would acquire most of the rest.

Parliament Joins the Fray. In late January, Parliament weighed in with a proposal before the Industry, Research, and Energy (ITRE) Committee that would abolish the GSA, turn responsibility for ensuring the Galileo system’s security requirements over to a new Committee on European GNSS Programs, and establish an Interinstitutional Monitoring Group (IMG) consisting of representatives of the parliament, the European Council’s Presidency, and the EC.

The proposed actions amending the EC’s draft regulation for deployment and commercial operation of Galileo were tentatively approved at a January 30 committee meeting. A final vote on the regulation as a whole by the committee and, later, by the full parliament had not taken place as Inside GNSS went to press.

Parliament clearly feels emboldened by the fully public procurement of Galileo for which the legislative body must approve a budget. In a plenary session at the Munich Summit, Etelka Barsi-Pataky, a member of the European Parliament, noted that “Galileo is a Community project, fully funded from the public budget — taxpayer money.

“We need very strong political control of the project,” she said, noting that in the 11 years since the EC submitted its first communication on satellite navigation, “We have produced a ton of paper, a lot of studies, a lot of discussion. What we need now is to build an operating system.”

Although a “substitute” rather than a full member of the ITRE Committee, Barsi-Pataky is the Galileo rapporteur, the person appointed by parliament to investigate an issue or a situation and report back to it.

Washington, D.C.
√ President Bush’s FY09 budget allocates nearly $1.2 billion dollars for GPS operations, says the Space and Missile Systems Center’s GPS Wing. If approved, that means the GPS III satellite program goes ahead with a first launch in FY14. That delayed target date looks like a result of last year’s Congressional budget cuts.

President’s FY09 Budget Proposes $1.2 Billion for GPS Program

The White House

President Bush’s Fiscal Year 2009 (FY09) budget released earlier this month proposes an allocation of nearly $1.2 billion dollars for GPS operations, according to the Space and Missile Systems Center’s GPS Wing at Los Angeles Air Force Base, California.

If approved, the budget would support continued development of the GPS III satellite program with a first launch in FY14. The somewhat delayed target date appears to match the prediction of the GPS Wing that the first GPS III launch would be set back a few months as a result of Congressional cuts in the FY08 GPS budget.

Congress Pares GPS III Funds, Slams Air Force Space Acquisition Efforts (updated 11/28/07)

The GPS III modernization program came up short in the 2008 fiscal year (FY08) Department of Defense (DoD) appropriations bill signed into law by President Bush on November 13.

In passing H.R. 3222, Congress reduced the president’s request by $100 million to $487.23 million for the budgetary year ending next October 1.

Military GPS M-code user equipment (MUE) did better, however: gaining $63.2 million on Capitol Hill, over and above the $93.27 proposed in the administration’s budget, for a total of $156.47 million.

As of late October 2007, China’s Compass (Beidou 2) Navigation Satellite System (CNSS) has manifested little change since the launch of its first medium Earth orbit (MEO) satellite in April 2007. Four geostationary satellites from the prototype Beidou system had previously been launched, the first on October 31, 2000.

The Two Worlds of Philip Mattos

Aside from messing about in boats on the estuary near his holiday house in Rock, a village in Cornwall, few activities delight Philip Mattos quite so much as solving the constellation of challenges involved in creating Galileo-ready receivers targeted to reach European consumers within two years.

Aside from messing about in boats on the estuary near his holiday house in Rock, a village in Cornwall, few activities delight Philip Mattos quite so much as solving the constellation of challenges involved in creating Galileo-ready receivers targeted to reach European consumers within two years.

Mattos is the chief engineer for GPS and navigation at STMicroelectronics R&D Ltd. in Bristol, the largest city in southwest England. Located near the mouth of the River Avon, Bristol’s economy centers on the aerospace industry and information technology. The area’s dependence on navigation traces back to its emergence as a major port city in the 12th century.

And while these facts about his home provide a nice bit of context, nothing really explains Mattos’s genius for GNSS. His prolific contributions, which touch hundreds of millions of people around the globe, seem all the more remarkable considering that the 1948 tractor he keeps for mowing his field represents the peak of technologies associated with his rural English childhood.

“Engineering clearly has formed me over the years,” he says with relish. “If something appears broken, take it apart and fix it!”

Since 2004, Mattos has focused on developing a new chip for a project funded by GR-POSTER, the acronym for the Galileo-Ready POSitioning TERminal Consortium. It’s the next big step toward the launch of Europe’s independent satellite navigation system, and Mattos has been breaking trail in this direction for nearly 30 years.

An Early Start in GPS

A Cambridge graduate, Mattos earned bachelor’s and master’s degrees in electronic engineering. His career began at British Telecom Research Labs, the equivalent to Bell Labs in the U.S. “They sponsored me through additional master’s degrees in telecoms and computer science from Essex; so, I was with them for about nine years,” he says. “At the end of my career there I was specializing in the architecture of the actual processor in microcomputers.”

When the British government set up the semiconductor industry in 1979, Mattos was recruited by INMOS (now STMicroelectronics) to help build the transputer, the United Kingdom’s first 32-bit micro. That’s when he happened across a feature in an electronics magazine that inspired him to develop a demonstration application using LORAN. “But there was a hold on the market.” he says. “Nobody wanted LORAN because GPS was ‘just around the corner.’ Of course, it stayed ‘just around the corner’ for about seven more years.”

So Mattos moved on to doing a GPS demonstrator, helped by a year’s posting to Colorado Springs in the United States. Back then, Mattos worked as “a team of one.” His presentations at conferences in Dallas and London led to partnerships with Inmarsat, Bristol University, and Columbus Positioning that supported taking a software-only demo to full-fledged prototypes integrating radio frequency, software, and hardware. The resulting handheld GPS was launched at the Royal Institute of Navigation conference in 1989 and the London Boat Show in 1990.

On to Galileo

When the sum of these efforts produced a dedicated chip for GPS in 1996, the way was opened for mass-market products and, in turn, increased resources for research. Four years ago, Mattos did the blue-sky thinking for the Galileo-ready chips now being perfected at five STMicroelectronics sites in Europe and India. At the moment, he divides his time mainly between England and Italy.

“In Italy, they work deep in silicon, doing detailed design and verification to check that the silicon we’re about to create is exactly what the people who designed the silicon asked for, and what I asked for when creating the specifications,” Mattos says. “The cost of manufacturing the chip is a huge investment. Our company does it from end to end, from initial design to final test.”

In addition to earning a Ph.D. from Bristol University for his work on GPS, Mattos holds nine patents: eight in the area of GNSS and one in telecommunications. His latest invention, patented earlier this year, provides extended use of broadcast ephemeris. Last year, he received a patent for new methods of processing multi-signal GNSS services, which applies to Galileo and GPS III signals.

His major innovations also include development of the HPGPS in the Teseo and Cartesio basebands as well as a new RF chip, applications which arose from his 2001 patent on accelerated acquisition of GPS signals and his 2003 patents on GPS code acquisition and GPS radio clock generation. Earlier, he obtained patents for microprocessor control of a packet-switched data exchange (1976) and the GPS radio design that led to the STB5600 RF IC (1996).

Asked to name a few milestones in his career, Mattos offered this list:

• Producing the prototype GPS/satcom for Inmarsat in 1990
• Developing the first fully integrated baseband with just 3 chips (compared to 14 in the 1990 model) in partnership with Panasonic, in 1995
• Creating a complete system in two chips, with the baseband having integrated memory and the RF portion being a single chip based on his doctoral work at Bristol University, in 1998
• Widespread acceptance of Vespucci in the automotive market, which changed from the ST20 processor to the ARM7 with embedded Flash memory, in 2001
• The success of Palinuro, with the RF front end on the same chip as the digital baseband, making a one-chip solution from antenna to PVT output, in 2003

The Future in GNSS

Currently, he’s involved in partnerships with Galileo Joint Undertaking in the GR-POSTER Project; ST teams in Bristol, Milan, Naples, and Catania; and lead customers (whose names are not public) on the following projects:

• A high performance 16-channel GPS plus RF chip for Teseo by the end of the year
• A high performance 32-channel GPS, with full PDA/PND functionality, for Cartesio (by early 2007)
• Cartesio’s extended version, with Galileo, for 2008

Mattos also makes time to consult on the next generation of GNSS chips including one-chip GPS (radio frequency plus digital) and high sensitivity GPS for indoor applications.

When the European Union and the European Space Agency launch their 30 Galileo satellites about two years from now, Mattos expects the most noticeable difference for navigation users will be the availability of service in urban canyons. Some indoor areas will be more accessible as well, though not those made of dense materials like concrete or metal.

“Galileo’s biggest benefit is that it can be combined with GPS and be compatible,” Mattos says. “If you’re down in an urban canyon, there will be enough satellites in the sky that your navigation system will continue to work. We need four or five satellites to operate properly and we don’t get that today in urban canyons. With GPS and Galileo together, we will.”

Mattos’s coordinates:
51° 32.450 N 2° 34.600 W


Engineering Specialties
“From 1990 to 1995 I was a team of one, so I needed to do everything – design engineering, system integration, software, hardware, signal processing, RFIC, and so on. Once the system was proven, more people were allocated and areas delegated. Now I specialize in architecture, system level design, advanced signals and DSP, tending to move away from GPS and towards Galileo. As a system specialist I advise the silicon experts, both RF and baseband, but leave the detail design to them.”

His Compass Points
• A childhood in the country, “before any of the technological stuff”
• Going to Cambridge
• Buying his first house “way out in the country looking out at the marshes and the river, which reinforced my existing love of the country, love of the water, and dislike of cities.”

Favorite Equation
The great circle distance between two points on the earth.

D = r x arrcos {sin φ1 sin φ2 + cos φ1 cos φ2 cos Δλ}

GNSS “Aha” Moment
I was demonstrating my software-based LORAN system, when a sales manager who was also a yachtie said, ‘This is pointless. LORAN will be replaced by GPS in a year or two.’ It’s 18 years later and the world is still having that debate!”

First Significant GNSS Achievement
In 1987 he worked in the same building as now, for his current employer (at that time, called INMOS) making the transputer, a then-revolutionary 32-bit microprocessor. “Having been advised that LORAN would be replaced by GPS, I did a demo of a software GPS, with one processor emulating the satellite, and a second processor performing all the DSP correlation, and demodulation in software to acquire and track the signal. The goal was to demonstrate the very high computing performance of the transputer processor: software GPS in 1987!”

Why he fell in love with GNSS
“My interests were boats, electronics, computers, and radio. How else to combine them all and play on company time? The challenge was to do something that covered so many technical areas, from antennas, low noise amplifiers, radio frequencies, digital signal processing, baseband, software, and map-matching, to dead-reckoning equipment, and have ownership of the entire design. This entire system was demonstrated in 1992, when a color map meant placing a six-inch CRT (cathode ray tube) display in a car. I have the TV to this day.”

GNSS Event that Most Signifies that GNSS has “Arrived”
Shipping the company’s Palinuro single-chip GPS. “Connect active antenna, power, and RS232 comm port to a PC/PDA and you have a GPS.”

Popular Notions about GNSS that Most Annoy
First, that the $2,000 box in the car is a GPS. “The GPS is the $15 module inside the box that delivers PVT.” Second most annoying, that the satellites track the user. “They have no idea you exist.”

Dream Device
An all-bands radio, initially a receiver but also a transmitter that listens to all the channels for all the aircraft, all the boats, and all the ships. It would display the active ones on screen and record activity so that one needn’t be present to monitor it. “You can get this information now, just not all in one place. It’s not what they call rocket science, because all the elements have been done. It’s a matter of bringing it all together. Such a device would let me feel a part of things when I’m at the office, working in the garden, or engaged in the ongoing refurbishment of our holiday house.”

What’s Next
Galileo in consumer vehicles throughout Europe.
