So in my story there was a zombie apocalypse a couple of years ago and there are only a small number of scattered survivors scratching a living as best they can (though that's about to change.)
My question is, can people still use GPS to navigate at sea and on land? The satellites are still up there. The people have power to their GPS devices. But I know there are ground stations that are part of the system. In this post-apocalypse world where nobody is staffing the ground stations, is the system still usable from the satellites?
Yes or no both work fine for my story - they'll figure the way eventually.
Related - what about plane navigation in this situation, where the pilot has nothing from the ground to help? ATC is not going to be that big a problem as there are no other planes around to avoid. But can she still find her way to her destination - in this case to Duluth Airport starting from north west Ontario?
Thanks in advance for any help!
