What are gps satellites?

GPS satellites are like super-smart helpers up in space that help you find your way on Earth.

Imagine you're playing hide and seek in a big park, but instead of just shouting "I see you," the park has a bunch of friends who can tell exactly where you are. That's kind of how GPS satellites work. They send out messages, and your phone or watch listens to them like a detective solving a mystery.

How they help you find your way

Each GPS satellite is like a friendly kid in space who knows the time super accurately. When it sends its message, your device compares that time with how long it took for the message to arrive. By doing this with messages from at least four satellites, your phone can figure out exactly where you are, just like solving a puzzle.

There are about 30 GPS satellites all orbiting Earth, working together so you can know where you're going whether you’re walking, biking, or driving. They're always sending messages and never taking a break!
