We have seen a lot of these predictions and rarely report on them. Most of the time not much happens so we tend to wait until after the storm arrives and, if there were noticeable impacts, report on those. In this case, though, we thought it would be a good idea to...

We were saddened to learn of Pat's passing. Her leadership within the PNT community included serving on the National Space-based PNT Advisory Board, and as president of the Institute of Navigation.     Obituary: Patricia Helen Doherty, 72 May 23, 1950 – July...

Image: Shutterstock Blog Editor's Note: Most people think about the eastern Mediterranean, Black Sea, or Baltic when they thing about regular and persistent GPS/GNSS jamming. And they are not wrong. But Norway's northern Finnmark region is right up there among the...

Image: DOD Blog Editor's Note: We are all for preventing problems rather than waiting for them to crop up and then running around figuring out how to recover. Think about how much easier it would have been to fix the levees in New Orleans BEFORE Hurricane Katrina. ...

Image: Shutterstock Blog Editor's Note: Several media outlets have described this as a 'UK sovereign PNT capability" or used similar language.  Well, kinda, but it is a augment for GPS, not a stand alone PNT capability. It's important to convey these kinds of things...

Blog Editor's Note: An interesting thought piece.  In the long run, there are probably much less expensive and more capable satnav options than GPS, both for civilians and warfighters. And if we are going to do head in that direction as a nation, we should do it as a...

Image: Gen. David O. Thompson from AF.mil Blog Editor's Note - We are always concerned when we see media reports like this. They invariably fail to note that most DOD efforts only benefit the very small percentage of GPS users who are military.  M-Code? The "M" is for...

Image: Shutterstock Blog Editor's Notes: We saw lots of reports last week like the one below. The implications being that Russia's GLONASS satnav isn't that great (true) and that GPS is better (also true). But not so fast with the western smugness that we are so far...

Image: Shutterstock Blog Editor's Note: Good article.. What more can we say?   It must be the time of year to think about Resilient PNT. Last week was a semi-annual meeting of the President's Space-based PNT Advisory Board (click to access video and slides).  And this...
