How does your GPS know exactly where you are?

How does GPS know exactly where you are? Every time you open a map on your phone, satellites thousands of miles above Earth help determine your location within seconds. But those satellites aren’t actually tracking your phone. GPS works by measuring the incredibly small amount of time it takes radio signals to travel from satellites to your device. In this video, we break down how GPS actually works, why your phone needs signals from multiple satellites, how trilateration determines your position, and why precise timing is the key to the entire system. You’ll also see why GPS satellites need atomic clocks, why your phone typically needs at least four satellite signals, what can cause your location to become less accurate, and why Einstein’s theory of relativity actually matters every time GPS calculates your position. GPS seems simple when a blue dot appears on your screen. Behind that dot is an extraordinary system of satellites, ground stations, radio signals, and incredibly precise clocks working together to determine where you are on Earth.
