Image: Shutterstock Blog Editor's Note: A good reminder for folks who like to think having VORs, DMEs, and ILS mean aviation is not dependent on GPS/GNSS. We found the following lists in the article and notice particularly informative: AREAS IMPACTED Kaliningrad...

Image: UrsaNav Blog Editor's Note: A similar topic to one we published from GPS World, though a longer piece that incorporates events since the first one was published. It also discusses more related issues, and the fact that France once cooperated in a Loran system...

Images: Shutterstock Blog Editor's Note: We think The Guardian missed the point on the story below, so we created our own headline for this post. Reading the article carefully reinforces the idea that the Russian government coordinates most of its interactions with...

Image: Shutterstock Blog Editor's Note: A good recap of the issues and reminder of this open and unaddressed vulnerability.  As a reminder, the U.S. government has twice committed to establishing an eLoran system. Once in 2008 and again in 2015. Some variation of the...

Image; Hawkeye360 Blog Editor's Note: Two timely articles today. Pretty easy guess that jamming GPS would be a part of the Russian invasion. The question really is about scope. It seems to be localized, so far. And, as the second article points out, "Thank you for...

Image: Shutterstock NOTE - we object to this headline. The receivers are not 'bad.' They were built according to the rules at the time. If anything is 'bad' its the FCC's decades long failure to consider receivers as part of the radiofrequency system. Blog Editor's...
