Case study notes

Introduction

The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit. The position of a user is calculated by measuring the distance to three/four satellites, taking the point of intersection in a process called trilateration. In order for this to work, each satellite carries an atomic clock so that the distance between the GPS receiver and the GPS satellite can be calculated through exact time differences.

How does it work or a deeper look

• If you are discussing a THING YOU CAN TOUCH, you must explain how it works, and the parts it is made of. Google around for an "exploded technical diagram" of your thing, maybe like this example of an MRI It is likely you will reference outside links. Please attribute your work.
• If you are discussing a PROCESS OR ABSTRACT CONCEPT (like fuzzy logic) you must deeply explain how it works.

Examples

Please include some example of how your concept is actually used. Your example must include WHERE it is used, and WHAT IS BENEFIT of it being used.
