Blog Editor's Note: As we have been reporting, Russia has repeatedly jammed the northern regions of Norway since 2017. This has resulted, of course, in significant concern among the nation's intelligence, military and security services. See this report in Defense...

Accurate and assured time is essential to so many facets of technology and modern life. Yet this "invisible utility," most often provided by weak and easily disrupted GPS signals, is little understood - even as far as agreed definitions of "accurate" and "assured!"...

Image: Aerospace America     Blog Editor's Note: Open systems with well understood formats and characteristics are easily adopted. That can be a good thing. It has led to the internet, GPS, and other such systems being great enablers of efficiencies and...

Blog Editor's Note: Late last year Durk Van Willigen gave a presentation at the Royal Institute of Navigation's International Navigation Conference at Bristol. In addition to providing his insights on resilience, the presentation included these images of a really,...

Blog Editor's Note: While aviation users are not as dependent upon GPS/GNSS as those in other modes of transportation, outages do have significant impacts.  We have written before about the tension between the government's need to test and exercise, and the impacts...

Blog Editor's Note: The Danish firm Risk Intelligence recently made its September 2018 report on government interference with GPS and its impact on shipping available on its website. The report cites numerous areas around the globe subject to chronic GPS jamming and...

SAE International is a global association of more than 128,000 engineers and related technical experts in the aerospace, automotive and commercial-vehicle industries. They are perhaps the world's largest voluntary consensus standards development organization. Last...

Image: Inside GNSS Or Just Navigation? Blog Editor's Note: Another great article by Dee Ann Divis. It is interesting that while researchers say they are working on PNT, often they are only looking at positioning and navigation. Timing is important to land mobile...

The 116th Congress has organized itself and committees are beginning to develop their agendas for the next two years. As a part of this they will often hold a hearing to get input from the public on what issues need to be addressed within the committees' areas of...

Blog Editor's Note: We often talk about "GPS dependency" in terms of technologies and systems that use GPS/GNSS signals. Rarely do we think of people as being one of those systems. But people, unlike most technological systems, can learn and unlearn. Even those who...

Blog Editor's Note: We wonder if the Defense Intelligence Agency might go one step further and say that, of all our satellites, GPS satellites and signals are the most vulnerable.       OPINION China, Russia see our satellites as a vulnerability by Erin...

Blog Editor's Note: We have posted on this before, but this alert bears repeating. It is the kind of thing where if we can help one person avoid one problem, it will have been worth the effort. MEMORANDUM FOR U.S. OWNERS AND OPERATORS USING GPS TO OBTAIN UTC TIME...

Blog Editor's Note: We are not sure if this is another instance of Russia jamming GPS in Norway or part of the most recent spate of instances. Suffice it to say that Russia has been jamming GPS in northern Norway a lot. This is a good article as it reminds us that GPS...

Blog Editor's Note: We have reported before on the tension between the government's need to test and exercise GPS disruptions and aviation interests that can suffer economic losses and other problems. This is particularly interesting as aviation has a network of...
