Tips on Buying Your First GPS Unit

by: Adrienne MacDonald

An introduction to GPS technology, the various types of GPS systems on the market, and tips on choosing a unit that is right for you. Anyone that enjoys the great outdoors has probably heard of GPS devices. They can come in handy when you are hiking, boating, biking, or doing just about anything else in the great outdoors. Twenty years ago, you had to rely on a compass the position of the sun and stars and your own common sense. Not anymore! Now you can have a handy little device that can pinpoint your exact location at any given time of day. If you are in the market for a GPS device, it is important that you understand how it works. Since the GPS devices rely on air signals, you must have a GPS receiver and a clear view of the sky for them to work. When your device is turned on it is actually linking up with 27 orbital satellites in place around the planet. Four of the nearest satellites are located and the distance from them to you is calculated via the hand held device. The process is called trilateration. Based on that, the GPS device can determine where you are on the planet. Pretty neat huh?

A GPS device is like a map on steroids. First of all, it always gives you that little “You Are Here” dot – you no longer need to figure that out for yourself. And all you need to do is tell it where you want to go and it will plot the course for you. It doesn’t end there, however. New GPS units will provide you with voice guided directions for the entire trip, tell you where the nearest gas station is, and will even put you back on course if you take a wrong turn.
