Actions Necessary to Reduce Vulnerability and Ensure Availability By Brad Parkinson (From the 25th Anniversary GNSS History Special Supplement) Introduction About 40 years ago, we had a vision for positioning, navigation, and timing (PNT).

Two April Disruptions Furnish Fodder for Multi-GNSS Receivers and Alternative PNT In an unprecedented total disruption of a fully operational GNSS constellation, all satellites in the Russian GLONASS broadcast corrupt information for 11 hours, from just past midnight until noon Russian time (UTC+4) on April 2 (or 5 p.m. on April 1 to 4  a.m. April 2, U.S. Eastern time).... read more

Out in Front: How Much Farther?

May 1, 2014By

For some years now, we have been talking about GNSS interoperability. The concept has received so much careful attention at conferences, in R&D laboratories, in international working group forums, and behind closed high-level government and military doors, that one might understandably conclude that we have talked interoperability into existence. Not quite. Not nearly. Not by the farthest, if measuring into... read more

Expert Advice: The Low Cost of Protecting America

January 1, 2014By

By Dana A. Goward Highly precise and free for use by anyone with an inexpensive receiver, GPS and other GNSS are great. Their navigation and timing signals have been incorporated into nearly every aspect of modern life, from synchronizing power grids to financial systems, the Internet, telecommunications, and transportation. The U.S. Department of Homeland Security estimates that these signals are... read more

Qinetiq, Rockwell Demonstrate Multi-Constellation Galileo/GPS Secure Positioning for Governmental Applications

November 12, 2013By

On August 30, QinetiQ and Rockwell Collins demonstrated the first joint satellite navigation positioning using live signals from the encrypted governmental services from the U.S. Department of Defense (DOD) GPS Precise Positioning Service (GPS-PPS) and the new European Galileo Public Regulated Service (PRS). The signals on GPS L1 and L2, together with Galileo PRS L1A and E6A, were processed and... read more
