It's hard to imagine a world without GPS, suffice to say we'd be lost. And critically, emergency services use GPS to locate callers from their phone signal, the satellite communications could possibly save your life. We depend on Global Navigation Satellite Systems (GNSS) for anything from the GPS services on your phone, to travel information and supermarket just-in-time stock management to make sure produce arrives as fresh and as quickly as possible. "There are a number of satellite missions that society depends on that just wouldn't work," James Davis, a geophysicist at Columbia University's Lamont-Doherty Earth Observatory, said in a statement "I cannot think of how GPS would work on a flat Earth," said Davis.
It is likely that satellites would not exist if the Earth were flat, as they would have trouble orbiting a flat plane.
