In many areas of life it's difficult to tell whether or not your GPS/GNSS signal is being deliberately disrupted or something else is going wrong. It is often much easier in aviation and maritime operations. A presentation by Spirent's Guy Buesnel and Steve Hickling...

Blog Editor's Note: We were very encouraged to see the announcement of this effort by the DHS Science and Technology Directorate. We are sure that it will contribute to the PNT community's overall knowledge base. Yet there is a lot of science and technology available...

DOT Ignoring GPS Vulnerabilities — Again November 30, 2018  - By Dana Goward The U.S. Department of Transportation’s most recent document preparing for the future of self-driving cars almost entirely ignores positioning, navigation and timing (PNT) needs, according to...

On the 14th of November the Senate passed the Frank LoBiondo US Coast Guard Authorization Act of 2018. Included in that bill was the National Timing Security and Resilience Act of 2018.  The bill was initially proposed last year in the House by Congressmen John...

Blog Editor's Note: This two-part report by Katherine Dunn has reached many in business who have not been aware of such problems heretofore (see some of the comments on her article on line). It is a good reminder that, while such things may seem matter of course to...

Blog Editor's Note: This bill, which passed the Senate on the 14th of November, requires the Secretary of Transportation to establish a terrestrial national timing signal to provide a backup for GPS timing.  It originated in the House of Representatives several years...

Blog Editor's Note: Maritime GPS disruptions have been reported elsewhere, but seem to be particularly common in this part of the world. Electronic navigation signals from the Saudi Arabian Loran-C system and the Russian Chayka/Loran-C system are available for use...

Blog Editor's Note: Russia has been jamming and spoofing GPS repeatedly and over broad areas since at least 2016.  In the below "Inside GNSS" article about their most recent jamming events, RNTF President Dana A. Goward is quoted about the reasons:  "Russia has very...
