What is GPS?

GPS stands for Global Positioning System, and it helps us find where we are on Earth, like a super-smart map in the sky.

Imagine you have a toy car that can tell you how far it has gone from your bedroom to the kitchen. GPS works kind of like that toy car, but instead of just telling you how far you’ve walked or driven, it tells you exactly where you are.

GPS uses satellites, tiny robots in space, that send out messages all around Earth. Your phone or your car has a special receiver that listens to those messages and figures out where you are by comparing the time it takes for each message to reach you.

It’s like having four friends who shout out their names from different parts of a park, and you use how long it takes to hear them to guess where you’re standing.

GPS is used in many places, like when your parents are driving and they follow directions on the phone, or when you play video games that know where you are. It’s like having a bunch of smart helpers watching over you from up high!
