Blog Editor's Note: We have heard conflicting reports about GPS effectiveness at high latitudes. Also that Russia's GLONASS satnav system is specifically designed to provide good coverage to the Arctic. This makes sense as the Arctic is a big area of investment and...

Blog Editor's Note: Two different opinions recently published by Defense One. It is interesting, though, that their disagreement is based on the costs of satellites and anti-satellite weapons. Both agree that over-reliance on space systems is a really bad idea. From...

Blog Editor's Note: I have an analog clock in my office that I never have to adjust because it is synced with WWV. While neither WWV nor WWVH are sufficiently precise for most commercial applications, it would be interesting to know which users will be impacted if...

Blog Editor's Note: This new risk center was mentioned at the recent DHS Cyber Security Summit. Mr. Bob Kolasky, it's new leader, has told us that GPS and PNT issues will be one of the center's focus areas. "It is very much top-of-mind" Kolasky told us before the...

Blog Editor's Note: It seems that every forum lately that talks about positioning, or navigation, or timing, is focusing on resilience.  GOOD! The tools for all kinds of disruptions are becoming more widely available, cheaper and easier to use. We need to be prepared,...

Blog Editor's Note: GPS is really great and the the US government has actively encouraged its use for decades. It has has brought untold increases in efficiency, brand new services, and new businesses. At the same time it under girds every network and most of our...

Blog Editor's Note: Tracking and peoples' reaction to it is an entire field of study on its own. While reading "Pinpoint - How GPS is Changing Technology, Culture, and Our Minds" we were surprised to come upon an entire chapter devoted to behavioral science. On...

Blog Editor's Note; If you don't want to give up your car's electrical outlet to power your GPS jammer, this new device uses the On Board Diagnostic (OBD) port. We like that the vendor is very careful to explain the limitations of the equipment. It only impacts L1,and...

Blog Editor's Note: We love interesting articles that talk about new PNT technologies.  But when they talk about "replacing GPS," well, that's a bit of hype too far, in our opinion. Especially since, while all the systems described seem interesting, all fall short...

Blog Editor's Note: More recent incidents and concerns tend to make many of us forget about the lessons of the January 2016 GPS timing glitch. I wonder how much we learned and how much different things would be today if it happened again. Bloomberg Businessweek July...

“PNT vulnerability very much top of mind” says Assistant Secretary We were misinformed that the DHS Cyber Summit was not going to include discussion of PNT issues. DHS’ Acting Assistant Secretary for Infrastructure Protection, Bob Kolasky told us that PNT issues will...

The National PNT Advisory Board will meet by teleconference/WebEx at noon EST on the 6th of August. Agenda items are: Finalize and Approve the National Space-Based PNT Advisory Board Topics Paper Finalize and Approve the National Space-Based PNT Advisory Board...

Blog Editor's Note; It is good to see DHS concerned about this issue. We wonder why, though, they are focusing only on GPS sensors as GPS/GNSS signals are inherently NOT resilient ...     2018 Resilient GPS Equipment Demonstration for sUAS   Solicitation Number:...

Blog Editor's Note: The RNT Foundation has filed several items with the FCC concerning adjacent band interference with GPS/GNSS. Subsequent to Ligado's most recent modification to their application, we joined a number of other organizations expressing continuing...

Blog Editor's Note: A recent "Inside GNSS" article discussed broad efforts being made across organizations and companies to address increasing concerns about GPS vulnerability. One of the events cited was a NIST workshop the RNT Foundation helped develop. A MITRE...
