5000 Words About: Global Positioning System

We surround ourselves with marvels of technology, but often have little idea of how they work. Andrew Hazleton is an engineer and writer who explains the technology that makes up our lives. He uses simple language and detailed explanations.

In this book, Hazleton examines how a GPS system determines location and navigates to your destination. Hidden in the familiar little box on your dashboard is a world of precise timekeeping, orbital mechanics, electronic wizardry and state-of-the-art hardware and software.

When you finish this book, you won't know how to design your own GPS. But you will know how the system works, what technologies are needed to make it function, and some of its limitations.

It won't make rush hour traffic any better, but at least you can appreciate the hard work your satellite navigation system performs on your behalf.
