Your phone uses signals from special satellites to know where you are. Imagine you're playing hide and seek in a big park, and each friend who calls out helps you guess where you are, that’s how GPS works! The satellites send messages, your phone listens, and by figuring out how long the message took to arrive, it knows exactly where you are.
Examples
- You open a map app and see your location without asking anyone.
- Your phone shows you the closest coffee shop while you're walking down the street.
- Your parents get notified that you've arrived at school.
