What is GPS?

GPS Satelite

GPS is an acronym for Global Positioning System. It is a satellite based navigation system that was created by the US military but anyone around the world can use it. It is ideal for ships, planes, cars, and hikers. The cost of a handheld GPS receiver starts at about $100. A GPS receiver will tell anyone where they are within about 100 feet, anywhere on the planet.

You should take the time to practice with a GPS receiver before you try to understand the technical details of the GPS system. They are surprisingly simple to use, given all the technology involved. You can learn most of what you need to know within and hour or two of opening the box. They usually come with a tutorial, use it! It only takes about 30 minutes to follow this tutorial and you will learn a great deal in a short period of time.

Unfortunately, most tutorials do not explain how to use the GPS unit with a topographical map.
