Why Does Your Phone Know Where You Are?

Your phone has a tiny brain inside it that uses signals from space to know where you are. Like when you play hide and seek, your phone listens for whispers coming from satellites up in the sky, those whispers tell it how far away you are from each satellite. It does this with four or more satellites at once, and then adds everything together like a puzzle piece so it knows exactly where you are on Earth.
