didnt know that never used gps . on the occasions need to navigate use good old fashioned map and compass .
hence figured the gps outage would effect all the electronic gizmos people rely on to navigate these days .

They don't affect ground level or low altitude. It's only high and medium altitudes that will be affected.
with all due respect, zap, why don't they turn off the GPS of the individual craft involved in the exercise?.....the amount of possible accidental harm from this wide area shutdown would seem to make this problematic.

I don’t recall but would cell phones not be impeded even if was at all altitudes? I thought they used cell towers for gps coordinates without gps satellite help?
