Could the world cope if GPS stopped working? “GPS consists of 24 satellites that all carry clocks synchronised to an extreme degree of precision. When your smartphone uses GPS to locate you on a map, it's picking up signals from some of those satellites - and it's making calculations based on the time the signal was sent and where the satellite was. If the clocks on those satellites stray by a thousandth of a second, you'll mislay yourself by 200km or 300km. So if you want incredibly accurate information about the time, GPS is the place to get it. Consider phone networks: your calls share space with others through a technique called multiplexing - data gets time stamped, scrambled up, and unscrambled at the other end. A glitch of just 100,000th of a second can cause problems. Bank payments, stock markets, power grids, digital television, cloud computing - all depend on different locations agreeing on the time. If GPS were to fail, how well, and how widely, and for how long would backup systems keep these various shows on the road? The not very reassuring answer is that nobody really seems to know.” (Adapted from: https://www.bbc.com/news/).
