Somewhere up there in space, about 12,000 miles above the surface of the planet, more than 30 GPS navigation satellites orbit Earth. Thanks to them, you don’t need to use the sun, moon, and constellations to find your way!
People depend on GPS much more than you might think. One of the reasons why GPS satellites are so crucial for people is because they carry onboard atomic clocks. And those are the very clocks which are responsible for all the time in the world! Should they malfunction, it would bring an end to pretty much everything, from electric power grids to the internet, digital TV and radio, and cellular communication. So how bad would it be if GPS suddenly stopped working?
