Knowing an exact geographic position and finding the way to another location always has been a challenge no matter at which time we look at. Over the past several thousand years, mankind has found countless innovative ways to master this task, leveraging geographical characteristics, constellation of planets and stars and later also tools such as sextants and compasses. Today, navigation is made easy with most people relying on detailed maps and road atlases. For a few years, many of us learned to value the usability of online services such as Mapquest that simplify navigation tasks and help us find street routes.

However, Global Positioning System (GPS) continues to revolutionize how we get from A to B. Interactive maps and real-time satellite tracking have the potential to automate virtually all of our navigation needs. Whether it is simple navigation for weekend hiking or sophisticated guidance for cross-country treks, GPS is quickly moving into our everyday life and recently has hit price points that are reasonable and affordable for most of us.
