Humans have always sought to use tools to help them survive. Through out millennia, Mankind has used tools to adapt and overcome the sometimes harsh environment he has found himself in. As time has dragged on, Man has fashioned ever more complex and high tech tools. These tools have enabled him to build the hunt for game, build the Pyramids and cross oceans. Today, that same thirst for invention has given us GPS, or Global Positioning system

It seems every other person has a GPS device of some sort. And why not? GPS tracking devices allow people to keep track of their loved ones and their vehicles and allow them to keep from getting lost on their out of town trips. While it is nice to admire GPS for the technological marvel it is, one should be informed of what GPS is and how it works.

Satellites that are orbiting the Earth are the key to making GPS work. They communicate with the GPS devices on the surface of the Earth. The signals from the satellites are relayed to the units on land. The signal is decoded and interpreted by the unit and data is graphically displayed on the screen. This data can show up as longitude and latitude or could be as simple as displaying what exit off the highway the driver should take next.

GPS was developed in the 1970′s and early 1980′s exclusively for the United States military to use. For almost two decades, the wonderment that is GPS was the U.S. military’s sole domain. Then in the 1990′s the technology was made available to the general populace. After it became commercially available, GPS slowly began its appearance int he marketplace and gradually accelerated its adoption into our culture to the point that a good GPS unit can be had for under $200.

All this makes GPS technology affordable to consumers everywhere. And since it has become more affordable, GPS systems are now seemingly in every vehicle on the road. By helping you make sure you are going the right direction, GPS saves you time, money and frustration on your next trip.

You can purchase a GPS unit in one of two ways. You can buy a unit for your dashboard and remove it each time you leave the vehicle alone. Or you can get the GPS unit installed into your dashboard as an option when you purchase the vehicle.

The last thirty years, GPS has gone from military hardware to an item on our dashboards that we cannot live without. What a journey, huh?
