How Does I don't need a map - I have a GPS Work?

I don’t need a map, I have a GPS, which is like having a super-smart friend who knows the way and tells me exactly where to go.

Imagine you're playing hide-and-seek, and your friend has a special toy that shows them how far away you are. That’s kind of like what a GPS does. It uses signals from satellites, tiny little robots floating high up in space, to figure out where you are on Earth.

How the GPS Works

Your phone or car has a GPS receiver, which talks to those satellites using special messages, like sending postcards. The more postcards it gets, the better it can tell where you are and how to get somewhere else.

It’s like having a compass that doesn’t just show directions, it knows your whole route, just like your parent knows the way from school to home without looking at a map. You might not know how it works, but you trust it, just like you trust your friend in hide-and-seek!
