European Commission to Monitor GNSS Patents Worldwide

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.

Spoofing

Sometimes 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”.

Adding Intelligence to Receivers

GNSS receivers and users, along with the critical infrastructures and services they support, face a growing threat from jamming, spoofing, and meaconing (JSM) events.

Several proposals for GNSS spoofing detection and signal authentication have been proposed over in recent years. These have focused mainly on adding cryptography elements to the GNSS signals and detecting RF characteristics of undesired signals.

Something Old, Something New

The past 15 years have witnessed tremendous developments of new and modernized satellite-based navigation (satnav) systems, including GNSSs, regional systems, and space-based augmentation systems (SBASs). These have been enabled by the original designs of GPS and GLONASS and, in turn, have stimulated the design of satnav signal structures with different characteristics from those pioneer systems.

BeiDou Gets Ready for the Global Marketplace

The fourth China Satellite Navigation Conference (CSNC 2013) wound up its three-day run on May 17 in Wuhan — by all measures a clear success for an event that has become the nation’s leading international GNSS forum.  

A key take-away from the event: China is rapidly preparing to bring BeiDou products and technology into the international marketplace is encouraging its industry to build an internationally applicable knowledge base in standards, patent law, and intellectual property rights (IPR).

BeiDou

Since announcing plans in late 2006 to build its own GNSS system — BeiDou-2 (BDS), China proceeded quickly to establish a fully operational regional system late last year with a clear plan to complete a global system by 2020.  

Beginning with its first launch in April 2007, BDS has put 16 satellites in orbit, some in dual launches, with 14 BeiDou space vehicles currently transmitting healthy signals: 5 in geostationary orbits (GEO), 5 in inclined geosynchronous orbits (IGSO), and 4 middle Earth orbit (MEO) spacecraft.
