back to the old fashioned compass and maps... for civilians
somehow i am guessing this is not a problem for the government's GPS sats.
Seems to me that it wasn't all that long ago that civilian GPS was "second rate" as the precision was left very "wide", at least until the '90's, so that spys could not use our system to pinpoint targets. I've often assumed that during an "event" the system would be returned to such a state, making your GPS less accurate, especialy around military intallations.
There is much talk that impending solar events would also wipe out satellites. I was thinking about learning how to use a sextant.
Civilian GPS wasnt even available until like 2000. Unless there was another GPS system Im not aware of.
