I think that even with a rudimentary and incomplete knowledge of the road network one could detect spoofing a car navigation system. The car would show up inside buildings and farm fields and lakes. You'd see this even on a very poor map.
If the spoofer moved the signal even 200 yards the match to the roads would be total rubbish and non sense. It would be detectable even using very old maps with many segments missing On Mon, Aug 14, 2017 at 3:10 PM, Ron Bean <t...@rbean.users.panix.com> wrote: > >In a car it is even easier.
