High performance positioning system

A high performance positioning system is basically a way to find out exactly where things are located in the world. Imagine you are playing a game of hide and seek, and you need something to help you find your friends who are hiding. A high performance positioning system is like your superpower to always know where your friends are.

It works by using something called satellites, which are like really, really high up in the sky in space. These satellites send signals down to special devices on the ground (like on your phone, for example), and the device uses those signals to figure out where it is.

There are different types of high performance positioning systems, but the most common one you might have heard of is called GPS (Global Positioning System). It's like a super map that shows you exactly where you are on the planet.

High performance positioning systems are really useful for all kinds of things, like figuring out how to get from one place to another, tracking things like airplanes or boats, or even finding lost pets. It's like having a secret GPS tracker for anything you want to keep track of!
