How Do Maps Know Where You Are?

Maps know where you are using special signals from the sky. Imagine there are invisible helpers in space that send messages to your phone, telling it how far away they are. Your phone uses those clues to figure out exactly where you are on Earth. It’s like having a friend who can tell you where you are just by looking at you from far away.
