[Lex Computer & Tech Group/LCTG] Lessons From Ukraine -- US GPS satellite system is (needlessly) vulnerable

[Robert Primak]

 Stay tuned -- As part of next week's Potpourri, I'll take some time (under 20 mins., plus discussion) to outline what's happening and what is supposed to have been done about this problem two decades ago. And what can be done (and is being done) today. Lots of references, so I'll post a document to our Chat on that day.

I can do a mini-topic on this next week for Potpourri.

This CNet Report goes into significant details about ground-based alternatives and backups for GPS, including at least one which could be on every cell phone in just a few years. Ukraine was already mentioned as a place where GPS from satellites had been jammed. This was 2019-2021.
