How GPS Works is something we rely on every day without noticing it. A phone shows a blue dot, gives clear directions, and quietly follows us wherever we go. Behind this simple experience is a careful scientific system using satellites, time, and signals traveling from space to Earth. GPS does not see people or track movement visually. It listens to precise time stamps sent by satellites orbiting high above the planet. By measuring tiny differences in time, devices calculate
