What is Global Positioning Systems (GPS)?

GPS stands for Global Positioning System, and it helps us know where we are on Earth, like a super-smart map that’s always with you.

Imagine you have a toy car that can drive anywhere in your room. But how would it know where it is? It could ask other toys for help! That's kind of how GPS works.

GPS uses satellites, tiny machines floating high up in space, like astronauts who never come back to Earth. These satellites send out messages that tell your phone or watch the time and where they are.

Your device listens to these messages from several satellites at once, like asking a few friends for directions all together. By figuring out how long it took each message to reach you, your phone can guess exactly where you are, just like how you might know where you are in your room by counting steps or looking at familiar objects.

GPS is used everywhere: in your phone, on trucks that deliver toys, and even on spaceships! It helps people get from one place to another without getting lost, like having a friendly guide who knows all the shortcuts.
