Lecture: Satellite Navigation: Six Decades of Serendipity

Satellite Navigation: Six Decades of Serendipity

From measuring the Sputnik signal Doppler effect to carrier phase precise positioning, and from the massive use of GPS’s coarse acquisition signal to codeless techniques, the history of satellite navigation has many examples of satellite signals being used in a way that was not initially foreseen by their designers. This is a natural consequence of GNSS worldwide coverage and the long lead times for infrastructure development with respect to the fast-paced market and receiver technology evolution. This talk will present some examples of serendipitous use of satellite navigation and will show some lessons we can learn from it for the near future. Galileo, the European GNSS, is not exempt from this phenomenon, and the talk will also cover how the Galileo infrastructure, initially developed to provide a global integrity service, is being used for different purposes.

Ignacio Fernández Hernández has led over the last years the definition and implementation of authentication and high accuracy services for Galileo. He currently works for the European Commission, DG GROW, where he also chairs the Galileo Commercial Service and EU-US Resilience Working Groups. Before moving to the public sector, he worked in the European aerospace industry as an engineer and a manager in the EGNOS program. He has an MSc. from ICAI, Madrid, and PhD from Aalborg University, both in Electronics Engineering. He also has an MBA from London Business School and has been a Visiting Scholar at Stanford University, GPS Lab. He holds 10 granted patents in the domain of GNSS.

Prof. David Last

Member of International Advisory Council of Resilient Navigation and Timing Foundation, Alexandria, VA

Lecture: Spoofing GNSS – From Fiction to Everyday Fact

Spoofing GNSS – From Fiction to Everyday Fact

The idea that satellite navigation receivers could be commandeered to deliver hazardously misleading information began with James Bond. Now experts have attributed press reports and users’ records of anomalous GNSS behaviour in various countries and at sea to spoofing. These have disrupted navigation in the US, Russia and Europe, Iran and the Far East. Once only nation states had this capability; now hackers can spoof GNSS receivers at low cost, potentially causing substantial financial damage and risk to life. This presentation by two US non-profit organisations describes recent suspected spoofing events and seeks to understand the technology and the motivation behind them.

Professor David Last held a Personal Chair and was Head of the Radio-Navigation Group at the University of Wales, Bangor until retirement in March 2005 when he became a Professor Emeritus.

He was born in Manchester in 1940 and educated at The Manchester Grammar School. He was awarded the degree of BSc(Eng) by the University of Bristol in 1961, PhD by the University of Sheffield in 1966 and DSc by the University of Wales in 1995.

From 2005-2008, Professor Last was President of the Royal Institute of Navigation. He is a Past-President of the International Loran Association, a Fellow of the Institution of Engineering and Technology and a Chartered Engineer. He has published more than 500 technical and policy papers on navigation and communications systems, including the Global Positioning System (GPS), Loran C and enhanced Loran (eLoran), Galileo and other Global Navigation Satellite Systems, Maritime Differential GPS, Argos, Decca Navigator, and Omega. He acts as a consultant on radio-navigation and communications to companies and to governmental and international organisations and is active as an Expert Witness, especially in forensic matters concerning GPS. Professor Last is a Strategic Adviser to the General Lighthouse Authorities of the UK and Ireland. As an instrument-rated pilot he is also a user of terrestrial and satellite navigation systems.

In 2010 Professor Last was awarded the Harold Spencer-Jones Gold Medal of the Royal Institute of Navigation and in 2015 the Necho Award of the International Association of Institutes of Navigation.

James J. Miller

Deputy Director of the Policy & Strategic Communications Division with the Space Communications and Navigation Program (SCaN) at the National Aeronautics and Space Administration (NASA) Headquarters

Lecture: International Collaboration for Space Navigation in High Earth Orbit and Beyond

International Collaboration for Space Navigation in High Earth Orbit and Beyond

Over the past few years significant progress has been made to extend the use of Global Navigation Satellite Systems (GNSS) for Positioning, Navigation, and Timing (PNT) in High Earth Orbit (HEO). This briefing describes the results of international efforts that are enabling mission planners to confidently employ GNSS signals in HEO and how researchers are extending the use of GNSS out to lunar distances. Starting with nascent Global Positioning System (GPS) space flight experiments in Low-Earth Orbit (LEO) in the 1980s and 1990s, space-borne GPS is now commonplace. Researchers continue expanding GPS and GNSS use into—and beyond—the Space Service Volume (SSV), which is the volume of space surrounding the Earth between 3,000 km and Geosynchronous (GEO) altitudes. This has spawned exciting space missions through the promise of improved PNT performance, quick trajectory maneuver recovery, and enhanced on-board autonomy. However, there are limitations that need to be addressed when using GNSS signals in HEO because of their weak signal strength and the limited number of over-the-limb signals available from any one GNSS constellation.

With the recent development and deployment of multiple GNSS constellations, and ongoing upgrades to existing ones, multi-GNSS signal availability in HEO is set to improve significantly. Users could soon employ four operational global constellations and two regional space-based navigation and augmentation systems, respectively: the U.S. GPS, Russia’s GLONASS, Europe’s Galileo, China’s BeiDou (BDS), Japan’s Quasi-Zenith Satellite System (QZSS), and India’s Navigation with Indian Constellation (NavIC). When combined, such “super-constellation” of 100+ GNSS satellites greatly improves signal coverage and also increases the diversity of system architectures, frequencies and geometry. This, in turn, improves overall PNT performance and resiliency. With such new PNT capabilities underway, mission planners are setting their sights well beyond the SSV, even employing GNSS on upcoming missions such as the lunar-orbiting Gateway.

James J. Miller is the Deputy Director of the Policy & Strategic Communications Division with the Space Communications and Navigation Program (SCaN) at the National Aeronautics and Space Administration (NASA) Headquarters in Washington, DC. Mr. Miller is responsible for advising NASA leadership on U.S. and international Positioning, Navigation, and Timing (PNT) policy and technology issues. He is also the Executive Director of the National Space-Based PNT Advisory Board. Previously he was Deputy Director of the Office of Navigation and Spectrum Policy, Office of the Secretary, at the U.S. Department of Transportation. Mr. Miller is a commercial pilot with degrees in Aviation Flight, Aviation Management, Master of Public Administration degree from Southern Illinois University, and Master of International Policy and Practice from George Washington University.
