Imagine your smartphone is like a detective that can find out where you are by listening to signals from satellites in the sky. These satellites send messages, and your phone uses those messages to figure out how far away it is from each satellite, just like using clues to solve a mystery.
The Clues Come From Space
Your smartphone receives signals from multiple satellites at once. Each signal travels a different distance, so by measuring the time it takes for the signal to arrive, your phone can guess its position on Earth. It's like having four friends whispering secrets from different places, if you know how long each secret took to reach you, you can figure out where you are.
Examples
- Your phone knows you’re in a park by listening to satellites above you.
- When you open Maps, your phone uses signals from space to tell you exactly where you are.
- Your phone can find the nearest coffee shop without you telling it anything.
