GPS World‘s Leadership Awards were presented during a sponsored ceremony and dinner at ION GNSS+ 2015 in September in Tampa. The awards recognize significant recent achievement in four fields of position, navigation and timing: satellites, signals, services and products.

Nominations came from a group of industry executives and the magazine’s Editorial Advisory Board. Votes were cast by a slightly larger group of added VIPs from the community.

The Leadership Dinner was sponsored by Lockheed Martin, Harris, Raytheon and Braxton Technologies.


Satellites category winner

Marco Falcone, Galileo System manager, European Space Agency

Falcone led the Galileo program through a very difficult time, following the faulty orbital injection of the first two operational Galileo satellites in August 2014. He gave detailed descriptions of the anomalous launch, the planned activities to salvage what was possible from the event, and the likely impact of this event on the program. His mission control team worked around the clock to ensure that the satellites were configured so that final orbits would provide some utility to the Galileo program.

Remarks delivered by Daniel Blonski, system performance engineer at ESA, on behalf of Marco Falcone:

Marco Falcone, Galileo System manager, European Space Agency, winner of the 2015 Leadership Award for Satellites.

I would like to thank GPS World and the GNSS Community.

The recovery of satellites 5 and 6 of the Galileo constellation following the August 2014 launch wrong-orbit injection demonstrates the multidisciplinary capability of the European Space Agency and its industry. In fact, this recovery involved around 300 experts from our mission analysis and flight-control teams, system engineering signal and user receiver teams, space segment engineering teams, ground control and mission segment teams, as well as security operations. This award goes first of all to them for having believed in this recovery from the very first moment.

I apologise for not having been able to join this event in person due to the Launch and Early Operations Phase of the 5th Galileo Launch, which occurred Sept. 10. Galileo has now 10 (I repeat, 10) Satellites in orbit and operations are running smoothly. I count on GNSS chipset manufacturers to introduce Galileo constellation in their chipsets and eventually have Galileo-enabled devices as of next year.

In addition, the European Space Agency is also preparing for the future. In fact, we need already now to plan those system improvements that are necessary to replenish the constellation after 2020. These improvements go into the direction of higher positioning and timing accuracy, long-term validity ephemeris and faster time to first fix, improved interoperability with other GNSS and contribution to space users service volume, additional spoofing/jamming protection through authentication, enhanced online monitoring and signal-in-space flagging functionalities, as well as flexible digital signal generation to cope with the rapid time to market required for new services evolution.

Again, I thank you for recognizing the efforts of our teams at ESA and in industry. This award gives us even more energy.

I would like to thank GPS World for the opportunity to speak briefly at this year’s GNSS Leadership Awards.

At Lockheed Martin, we are proud to continue our support of the U.S. Air Force’s GPS program. We applaud the Air Force on this year’s 20th anniversary of the GPS constellation reaching full operational capability.

This is a tremendous milestone in the history of positioning, navigation and timing, as well as global navigation satellite systems. In addition, I’d like to recognize tomorrow’s 68-year anniversary of the establishment of the Air Force.

Lockheed Martin is honored to have contributed to the GPS milestone. Right now, 19 of our GPS IIR and IIR-M satellites make up about 60 percent of the current GPS constellation. It is a real privilege to be serving more than a billion military, commercial and civilian users every day. But our commitment doesn’t end there. If you had the opportunity to see the pictures in our booth, you know that Lockheed Martin will soon be introducing the world to GPS III — the most powerful GPS satellite ever developed — and GPS III will be the first GPS satellite to field the internationally compatible L1C signal, offering a new level of GNSS compatibility.

So, thank you. It has been an honor to speak before you, the international PNT community. Thank you for all that you do, and congratulations to all of tonight’s honorees.


New messages: Any SBAS, any GNSS

 

Signals category winner

Todd Walter, senior research engineer, Stanford University

This past year, Todd completed the message design for dual-frequency, multi-constellation SBAS, a huge step forward for aviation and other multi-constellation users. It means that SBAS will be able to provide corrections and integrity data for all constellations, leading to better accuracy and availability.

Remarks delivered by Todd Walter:

Todd Walter, senior research engineer, Stanford University, and Ellen Mitchell, senior communications manager, Space and Intelligence Systems, Harris Corporation.

I ’d like to thank GPS World for this award. In reality, the work on the dual-frequency, multi-constellation SBAS messages has been a long ongoing group effort. Numerous people at Stanford, the FAA, Zeta, MITRE, ESA, CNES, RTCA, EUROCAE and others have contributed to the development of the planned messages on L5. ESA and CNES in particular have been handling the document management and comment resolution.

I would also like to especially thank my colleagues at Stanford University for their hard work and support.

The new messages now planned for L5 will allow any SBAS to correct any constellation that it chooses. Rather than only supporting L1-only signals on GPS, as the current systems do, SBASs will be able to support the use of two frequencies, using as many constellations and satellites as they choose to monitor.

We will no longer need to suffer availability outages due to limited satellite geometries. Furthermore, we will not suffer availability limitations due to ionospheric disturbances. Dual-frequency operation will allow precise vertical guidance throughout the globe, and in particular in equatorial regions.

The original L1 SBAS specification took more than 20 years of development. The new dual-frequency multi-constellation specifications are even more complicated and will require a similarly long development time. Our latest effort started many years ago when the GPS L5 was initially planned to be fully operational in 2018. Since that time, the GPS L5 date has moved back to 2024.

And in the mean time, the other constellations have progressed in their development. Our original efforts changed from a dual-frequency update to the SBAS messages into a truly multi-constellation concept.

In order to utilize new constellations and new signals for aviation, it is essential that the designs of these signals be stable and clearly documented. Furthermore, we require performance commitments from the constellation providers so that we can know what to expect.

To date, GPS leads the way in both of these requirements. Its signal designs have been stable and well described for many years, and it has published performance standards documenting the level of performance we can count on. There is widespread expectation that the other constellations will be very similar to GPS. However, this will not necessarily be the case.

We need to be prepared to deal with constellation-specific behaviors. Already we recognize differences in how GPS and GLONASS operate. We can only expect to uncover additional differences as we further utilize these constellations. Also, as we field new satellites and a new control segment on GPS, we can expect to see behavior that might be different from some of our fundamental assumptions.

It is important to plan for the future in order to incorporate new signals and new constellations; however, we must remain flexible with our planning to incorporate the reality of what we actually get.

— Postscript added in November: Thanks again for the award, it looks very nice on my desk!

harris-logo-200All about the signal

Remarks delivered by Ellen Mitchell, senior communications manager, Space and Intelligence Systems, Harris Corporation:

On behalf of the Harris Corporation and its more than 22,000 employees, I congratulate the award recipients this evening. It is particularly fitting that Harris has the honor of presenting the Signals award. As the GPS navigation payload provider, we create and deliver the GPS signal. Furthermore, our products help our customers better utilize the GPS signal and detect and prevent jamming of the GPS signal. We’re all about the signal.

This is our first year at this dinner as Harris employees. As a result of Harris Corp. acquiring Exelis on May 29, there now are 9,000 engineers and scientists in the new company. Many Harris colleagues have expertise in areas directly applicable to cutting-edge GPS payload development, for example. Current and future customers will benefit from working with this larger and even more capable new team.

We believe the combination of Exelis’ heritage of proven, assured GPS navigation payloads joined with Harris’ skill in the RF spectrum, satellite communications and reprogrammable payloads gives the new company a unique and innovative edge to support the next generation of GPS satellites.

We look forward to telling you more about our progress at next year’s Leadership Dinner. But this year, now, without further ado, I’d like to call Todd Walter to the dais to receive the Leadership Award for significant recent achievement in the area of Signals. Thank you for this opportunity.


After the awards ceremony and dinner, attendees played the Interference Event, competing to see which team could generate the strongest, most accurate signal, conveying critical information in a GNSS trivia game.

Thank you for a wonderful evening, and for offering the GPS World Leadership award to me. I am humbled!

Over the past decade, we have witnessed rapid progress in the development of multiple constellations of GNSS. While much of the focus has been on improvements in the availability, integrity, continuity, and inter-operability of multi-GNSS for PNT applications, a real winner as far as scientific discovery is concerned is in the use of GNSS in atmospheric and space weather studies. With a large and growing number of free open signals across a wide range of frequencies in the L-band, multi-GNSS will be able to provide distributed, low-cost, passive remote sensing of the atmosphere on a global scale. It is fair to say that there is no other technology that offers comparable potentials, coverage and cost-effectiveness.

In the coming decade, multi-GNSS will offer unprecedented opportunities for researchers to measure atmospheric and ionospheric parameters with high spatial and temporal resolution, and monitor atmospheric responses to solar, geomagnetic and other natural and man-made events.

This is an exciting time for multi-GNSS technological development and atmospheric research. I am fortunate to have the opportunity be a part of it and to explore and contribute to the interesting intersection between GNSS and the atmosphere.

Raytheon_logo-200Securing GPS against attack

Remarks delivered by Steve Moran, business development director, Raytheon:

Steve Moran, business development director, Raytheon

It’s great to be here with colleagues who understand the importance of a modernized GPS infrastructure.

I was asked to speak tonight because Raytheon is partnered with the Air Force in modernizing the GPS ground segment, which is at the core of the Air Force’s GPS modernization initiative. We like to call OCX the brains of GPS.

Over the past 30 years, GPS has ensured the safety and effectiveness of our nation’s warfighters and has become an integral component of global and national telecommunication, commerce and transportation infrastructures.

The GPS modernization initiative is essential to protecting our economy and the homeland, as GPS is an ingrained part of our nation and our world’s infrastructure. As critical as GPS is to so many key functions of daily life, it must be secured against cyber attacks.

The emergence of growing cyber threats creates daily headlines and drives an urgent need for GPS modernization. GPS has been recognized as an enabler of nearly all U.S. critical national infrastructure, such as the power grid or the water supply, and is a global utility that must be ready for emerging cyber threats.

OCX is a pathfinding program that answers that need and will deliver many other benefits to GPS users across the globe. Some of the new capabilities include enabling new civil and military signals; improving system accuracy and integrity; providing flexibility and evolvability to meet future mission needs; setting the bar for information assurance at an unprecedented level; and securely sharing information with net-connected users.

Raytheon’s OCX represents new approaches to emerging and even unimaginable changes and threats. We are confident that we have the right technology, team and resources in place to deliver the OCX program. It is critical we do so.

Thank you for inviting me here tonight, and I offer a sincere congratulations to all of the GPS World Leadership Award winners.


Novel GPS/GNSS uses just keep coming

 

Products category winner

Larry E. Young, GPS systems group supervisor, Jet Propulsion Laboratory

For many years he has been key in the development of radiometric technology. Specific areas of research include the development of GPS science receivers, multipath mitigation, sub-nanosecond clock synchronization, and sub-centimeter formation flying. He has been instrumental in developing the TriG multi-Global Navigation Satellite System receiver used in radio occultation to measure physical properties of the atmosphere, and key to NASA’s efforts to protect radionavigation satellite services from interference.

Remarks delivered on behalf of Larry E. Young by James J. Miller, deputy director, Policy and Strategic Communications, Space Communications and Navigation, NASA:

James J. Miller, NASA

James J. Miller, NASA

I would like to thank GPS World and the GNSS community.

I greatly appreciate the honor conveyed by this award. We all know that most advances in technology are made by a team of smart, enthusiastic and hard working scientists and engineers. JPL’s advanced GNSS receivers are a true example of teamwork.

In particular, Don Spitzmesser was a prolific inventor who could quickly conceive of, build and test novel circuits and antennas. I do not think he ever passed kitchen utensils without thinking of antennas. There are actually “heli-wok” antennas in space. The original helix was wound onto a glass, glued onto a wok backplane.

Lyle Skjerve was a highly skilled experimentalist. His previous job was detecting incoming ground-to-air missiles from the backseat of a Marine jet, and conducting electronic countermeasures to steer the oncoming missile off course. In addition to being smart, he was quick to debug problems during an experiment, and never gave up.

NASA headquarters has provided great support to GNSS technology, continuing the program Jim Miller leads today. I especially thank John LaBrecque, who provided critical early support for our speculative development of the “all-digital” receivers that produced 0.1-millimeter baseline precision.

I have been very happy to be able to work on GPS, and I am most thankful for the great group of colleagues I’ve had the fortune to work with at JPL and from other NASA centers.

My training was in experimental nuclear physics, where I was excited to measure the anomalous orbital magnetic moment of a neutron orbiting inside a superconducting magnet on the beam line of a tandem Van deGraff accelerator. I always enjoyed building measurement systems for first-time measurements.

After graduation, I got an opportunity to shift from nuclear scales too small to see (femptometer) to those too large to imagine (109 lightyears), characteristic of the distances to quasars. In all, that was a change of 40 orders of magnitude! The Jet Propulsion Laboratory hired me to help develop Very Long Baseline Interferometry to measure tectonic plate drifts in real time, and oh yes, to precisely navigate NASA’s interplanetary spacecraft.

Larry e. Young, GPS Systems group supervisor, Jet Propulsion Laboratory

From VLBI, it was a short step to GPS. Even though quasars produce the greatest power levels known to man, the power per square meter is much higher from nearby GPS satellites. Scientists and engineers at JPL and elsewhere quickly realized that GPS would provide precision geodesy as soon as the first satellites were launched circa 1978.

During a 1984 receiver shootout among JPL’s SERIES and SERIES-X receivers, the MIT Macrometer, and Texas Instrument’s TI4100, we set up for the night’s experiment near an old Bilby tower in the desert. These were used in the old days to provide line-of-sight optical surveys. Now that we had GPS, those days were gone, and we (the shootout adversaries) teamed together and pulled down the tower, burning it to ward off the pre-dawn cold. It seemed quite symbolic. Remember, back then the only time four satellites were mutually visible in the winter was during early morning.

The current set of JPL’s receiver developments started when Tom Yunck realized we could use radio occultation, developed for interplanetary spacecraft, as a very useful means to probe the Earth’s atmosphere.

Novel uses for GPS/GNSS just seem to go on and on, as smart innovative people around the world continue to find productive new applications. Some of the older ideas we are working on include using non-GNSS signals for navigation and remote sensing, using GNSS signals as sources for bistatic radar measurements, and applying the GPS receiver’s precise phase shifters to form dynamic multiple high-gain antenna beams.

As always, advances in computers and chips will help drive applications. Our receivers have always been software driven and flexible, and the exponentially growing throughput of digital devices shows no signs of slowing. We are at a point where the number of GNSS satellites is exploding. Other signal sources are available to aid navigation and remote sensing. I do not want to call the exact shot, but I am confidant that at least one person reading this magazine today is already thinking of a new GNSS breakthrough, which will delight the world with its applications!

braxton-logo-200Commercialization and competition

Remarks delivered by Edward Baron, director, Braxton Technologies:

I would like to thank the GPS World team for organizing another wonderful awards dinner. As a commercial product company, Braxton is honored to help sponsor this event recognizing tonight’s Product Award innovator.

I’ve heard a few requests for innovation from the government this week. If they’re interested in innovation, I would like to make an argument for commercialization and competition as a key driver for it.

Within the navigation world, the receiver and application markets are excellent examples where innovation is driven by daily competition in a commercial market. It’s amazing to see the accelerating global pace of innovation these highly competitive markets drive — creating new and better products, along with their economic and social benefits.

We are also seeing competition between the constellations themselves, as they compete to increase their global market share.

If commercialization and competition drive innovation, and could benefit the performance of a constellation, who will take steps to commercialize other segments to improve their performance?

Galileo has already taken steps to commercialize their ground operations, and the U.S. is starting to talk about it.

It’s not possible to predict, but maybe in the future, GPS World will recognize someone for an innovation from a commercially operated GNSS system.
