Smartphones use tiny signals from space to know where you are. Like a superhero map, satellites send messages down to your phone, and it uses those messages to figure out where you're standing, even in the middle of a crowd or on a busy street.
How It Works
Your smartphone talks to satellites that orbit Earth. Each satellite sends a message with a time stamp, and your phone listens for these signals. By measuring how long it takes for each signal to arrive, your phone can figure out where you are, like solving a puzzle from space!
Examples
- A smartphone knows when you're walking down the street by using tiny messages from satellites in space.
- Your phone tells you where you are even if you don’t have Wi-Fi, it just talks to satellites high above Earth.
- You lose your way in a city, but your phone knows exactly where you are because of signals from satellites.
