Image: Shutterstock Blog Editor's Note: This is the most recent warning issued for GPS disruption by the U.S. Maritime Administration (MARAD). For most of the last four or five years MARAD has had a similar warning active and on the books. The advisory points out that...

Image: KPIX This four minute piece from the CBS affiliate in San Francisco poses an interesting question.  There are certainly plenty of individuals, groups, and governments out there who might like to bring the U.S. to its knees. For example, in 1996 China suffered...

Image: Shutterstock Blog Editor's Note: A good overview article. One note, though. The $1.3B loss per day shown for the U.S. should we be without GPS comes from an RTI study done for the National Institute of Standards and Technology. That seems like a big loss that...

Image: Roi Mit Blog Editor's Note: An interesting reminder of a hallmark event within the PNT community. We are sure it had a significant impact on the folks at Tesla, and probably significant but probably lesser impact at other car companies.  We would have hoped...

Image: USAF, 2d Lt Jacob Lutz, AFRL/RV The House version of the National Defense Authorization Act for 2022, which begins on the first of October, requires the Secretary of the Air Force to provide a briefing to the Armed Services Committee about establishment of a...

Image:Shutterstock Blog Editor's Note: Good posting on Linkedin. A few thoughts: China has a huge edge over the US on 5G because of this. While US networks rely heavily (almost exclusively) on GPS, China has and is improving its comprehensive timing infrastructure. It...

Image: Shutterstock Blog Editor's Note: Lots of steps this week in the dance between the UK and EU. We have been on the verge of posting something about it several times. This seems like the end of this phase, though, so a good time to recap, which this article does....

Image: Shutterstock Blog Editor's Note: Another good article by RNTF member Diana Furchtgott-Roth. We appreciate that she is saying "new" terrorism peril to help wake up folks to a peril that has been out there quite a while and, as she points out, has been getting...

Image: Shutterstock Blog Editor's Note: This article is a interesting follow-on to GAO's report on "DoD Navigation Capabilities."  The article is worth reading for additional information it brings to light. The author also refers to a RAND report we have discussed...

Image: Shutterstock Blog Editor's Note: Great article showing, again, how China plays the long game.  Contrast their 30 and 40 year efforts with what seems to be a two-year planning window in the U. S. based on elections to the House of Representatives. Or maybe it is...

Image: Shutterstock Blog Editor's Note: A good overview article by RNTF International Advisory Committee member, Guy Buesnel.  It is good to see this message getting to places like India and to read about progress in Europe. Adding on to the article's European info,...

Blog Editor's Note: For years users have wanted to be able to include "resilience" as a requirement for PNT receivers in their purchase orders.  But it has been an elusive goal.  This is an important step in the right direction. An excellent development. Kudos to the...

Image: Shutterstock Blog Editor's Note: Another example of recent media highlighting that space is a dangerous place.  Measures like this are undoubtedly necessary. If for no other reason than to stay on a par, or hopefully slightly ahead of, the Chinese and Russians....

Image: U.S. DOT Blog Editor's Note:  This is a long piece so we won't add much to it with a long commentary. Only to say that since our inception we have endorsed the architecture/ system of systems approach as envisioned in the US govt's still-in-use 2008 National...

Image: Shutterstock Blog Editor's Note: Interesting article on  some space-based services with the potential to augment or offer an alternative to GPS/ GNSS.  As we have said before, space-based systems offer things you can't get from terrestrial and need to be part...

Blog Editor's Note: An excellent article by RNTF member Diana Furchtgott-Roth. Diana is a professor at GWU and previously served as Deputy Assistant Secretary for Research and Technology at the U.S. Department of Transportation. Diana is right on target. But we need...

Blog Editor's Note: We are seeing more and more about ASATs in the press these days. "Nesting doll" satellites with weapons inside, "kamikazee" satellites to crash into others - both courtesy of Moscow. Satellites with robo-arms that can grab other satellites and have...

Image: Shutterstock Blog Editor's Note: We are including two reports of the same event in this post. Several things of note. GPS is included in this discussion of cyber vulnerabilities, as is the case more and more often. That is a great development because...

Image: Shutterstock Blog Editor's Note: Granted this article is in an outlet about space. So it talks about GPS and GNSS. The larger issue, though, is that "Modern civilization would be lost without PNT."  But, yes, we over-rely on GPS so much it is almost the same...

Image: Shutterstock Blog Editor's Note: This is an important message we have heard before that bears repeating. Space assets are important, none more so that GPS. That means GPS is well protected. Also that it is the biggest challenge, and often the most attractive...

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...

Image Shutterstock Blog Editor's Note: This article has a number of interesting observations even though it conflates and confuses satnav and satcomms. The comments by the former head of the British Navy (First Sea Lord), who was also the nation's first minister for...

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: And those trucks are going to need rock-solid PNT.  Imagine sharing the road with automated semis that don't have it. Great article by RNTF member Diana Furchtgott-Roth.   Trucks Are Winning Automation Race Diana...

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...
