[time-nuts] Ships fooled in GPS spoofing attack suggest Russian cyberweapon

[Bob kb8tq]

Hi

Consider what your automotive GPS receiver does coming out of a tunnel or out from under
a bunch of trees. It still needs to work correctly in that situation. Same thing with 
a big rain cloud “over there”.  I don’t think you would want a receiver that  went nuts in those cases. 
I don’t think the military would want one either.
