Blog Editor's Note: An excellent summary of where America has been with PNT resilience and policy and where it needs to go. Interesting to note that the false rationale "GPS is expensive so we need to economize and have fewer other PNT sources" seems to have persisted...

Image: NASA Blog Editor's Note: Interesting assertion by two authors who should know what they are talking about.  Conventional wisdom has been that GPS is a constellation and anti-satellite satellites (ASATs) can only attack one other satellite. So very hard to...

Image: Shutterstock Blog Editor's Note: More outstanding work by Bjorn Bergman from SkyTruth uncovering massive location deception operations. In this instance, it seems as though there are no RF transmissions involved. In addition to the Wired article below, check...

Blog Editor's Note:  Our initial response to this article was "Duh!"  Aside from stating the obvious, it is a short piece that, initially, doesn't seem to add much to the community discussion. But it does point out that the problem "keeps getting worse."  And why...

Image: Shutterstock Blog Editor's Note: We thought we would offer this article as a follow-on to yesterday's post about GNSS as an instrument of national power. China is particularly good at using Bei Dou for soft power. Also note how they have used Bei Dou as to...

Image: Shutterstock Blog Editor's Note: This article is about GLONASS but could be easily about GPS, Bei Dou, or even Galileo. Certainly they are instruments of soft power (economic, political, etc,), And they have the potential for espionage and other national...

https://youtu.be/n69se2UCy_k   Yes, there are folks who know what time it is. And, yes, there are lots of folks who care! In fact, just about everyone cares, though most most folks don't realize it. Precise time underpins virtually every technology from...

Image: NOAA Blog Editor's Note: Interesting article.  Some thoughts about the RAND study mentioned, it said: Its not worth the cost to build another GPS-like system as a backup. We agree that duplicating GPS is not needed. (Note, China disagrees and has built GPS-like...

Image: Roke Manor Blog Editor's Note: We remember about 10 years ago when smart GNSS folks said this likely possible but not practical and wouldn't result in anything worth using. A number also said spoofing was theoretically possible but would never be a practical...

Image: Draper Blog Editor's Note: The need for this tool and others like it was highlighted in the DOD PNT Strategy, and in the recently released GAO report on DOD Navigation Capabilities. It will certainly provide a good first cut for evaluating technologies....

Image: Shutterstock Blog Editor's Note:  "Yeah, verily" to the author's point that anyone who talks about replacing GNSS is blowing smoke (and probably selling something). Unfortunately when we talk about ADDITIONAL or ALTERNATE sources of PNT, folks often wrongly...

Image: Shutterstock Blog Editor's Note: We have talked a lot in recent posts about the PNT gap between the U.S.A. and our adversaries China, Russia, and Iran. It is a gap that, as Beebe says in "The Russia Trap" (could also be titled "the China Trap") creates...

Image: RNT Foundation Blog Editor's Note: Up front caveat - the editor has deep Coast Guard experience and more that a passing familiarity with eLoran. In fact, he probably still is on the "bad list" of a major telecommunications company because he was not able to...

The General Accountability Office (GAO) released a somewhat scathing report about Department of Defense navigation programs this month. Among their findings and inferences were: Navigation requirements for projects and systems are often overstated with managers just...

Image: Shutterstock Blog Editor's Notes: This article hits so many of the strategic concerns around US  over-reliance on GPS.  And it is from a source in Japan, a country probably even more worried about China than the U.S., if that is possible. The article sub-head...

Image: Shutterstock Blog Editor's Note: This is a very interesting and compelling piece. Very timely also considering Galileo's avoidance maneuver in March. Also noteworthy is that the author appropriately defines risk as threat x vulnerability x consequence. So while...
