In a post-apocalyptic world without the internet and phone services, would a GPS program on a smart phone still work?
The satellites would still beam their signals, and you could charge a phone with a hand-crank radio. What I don't know is how a mapping app actually translates GPS location data. Does it receive data directly from the GPS satellites or does it receive data from cell towers, which wouldn't be working?
