Global Navigation Satellite Systems Engineering, Policy, and Design
Q: What is the effect of user and CORS height on NRTK performance?
Dr. Inder Gupta, The Ohio State UniversityChris Bartone, Ohio UniversityWith new signals and frequencies coming on line with modernized GNSSs, antennas play a more crucial role than ever in receiver system design.
Antennas are often an overlooked or undervalued aspect of GNSS user equipment.

Ismael ColominaSIDEBAR: Ismael Colomina’s Compass Points
Ismael Colomina began his career in 1982. “So, in a way,” he says, “I grew up as a professional at the same time GPS was growing up and maturing. GNSS has always been present in my working life; so, I never experienced the ‘GNSS, aha!’ moment. Rather, I never stopped thinking ‘GNSS, of course!’"

The sixth European Workshop on GNSS Signals and Signal Processing will take place at the University FAF Munich in Germany on December 5 and 6, 2013.
EquationsDuring the past two decades, the Global Positioning System, together with other GNSSes, has become an essential element of the global information infrastructure, with myriad applications in almost every facets of modern businesses and lifestyles, including communication, energy distribution, finance and insurance, and transportation. Ever-growing dependence on GNSS creates strong incentives to attack civil GNSS, for either an illegitimate advantage or a terrorism purpose.

As engineers painstakingly work their way through tests of the first full operational capability (FOC) Galileo satellite at the European Space Agency’s European Space Research and Technology Center (ESA/ESTEC) in Noordwijk, The Netherlands, European space sources admit that the new generation spacecraft’s maiden voyage will not occur until December 28, if then.

With a key Galileo patent dispute now set to enter its third year the European Union (EU) is moving to monitor GNSS patents around the world — a move that should give it insight into the competitiveness of European positioning, navigation, and technology (PNT) companies and a heads-up about future intellectual property (IP) issues.

Two British companies, QinetiQ and Nottingham Scientific Ltd (NSL), have partnered to demonstrate an Internet “cloud”-based technology that enables a wide range of high-volume, low-cost satellite navigation applications using Galileo’s Public Regulated Service (PRS).
The NSL-QinetiQ application allows a service provider to host secure navigation on one server in a back office, capture data from multiple locations and units, and subsequently verify the location of a remote user.

Tunis, where the new Galileo Euro-Med Cooperation Office (GEMCO) will open in October.A European-Union funded consortium invites companies and public agencies from Mediterranean countries in North Africa and the Middle East to submit ideas for extending Galileo GNSS and EGNOS use in the region.
Eligible ideas could be for a small pilot project or research study, a technical training plan, and/or a publication or article. The submission deadline is August 25, 2013.
The countries in the target area are Algeria, Egypt, Israel, Jordan, Lebanon, Libya, Morocco, Palestine, Syria, and Tunisia.
Logan Scott, LS ConsultingSometimes GNSS spoofing seems a bit like UFOs: much speculation, occasional alarms at suspected instances, but little real-world evidence of its existence.
As far back as 2001, a U.S. Department of Transportation Volpe Center report suggested that as GPS further penetrates into the civil infrastructure, “it becomes a tempting target that could be exploited by individuals, groups or countries”.

Old Congress Hall, MunichEuropean Space Solutions will take place at the Alte Kongresshalle in Munich, Germany on November 5, 6 and 7.
It is a 3-day conference for public agencies and industry to meet with users and developers of products and applications that could benefit from Galileo, EGNOS and Copernicus services and capabilities.
