[time-nuts] GPS Spoofing

[Bob Camp]

Hi

Loran-C wanders around enough all by it's self, with no need for help from others. Bumping it a bit this way or that is not an impossibility. A little bit of  added phase this way or that is all it would take. You would have to get the rep rate and timing right, but that's just the sort of thing a Time Nut knows how to do on the cheap.
