Choose the GPS receiver (global positioning system) to fit your needsWith so many GPS receivers entering the market, it may be difficult to know which one to choose. Originally designed by the United States Department of Defense, GPS has become a part of the mainstream, used by drivers, hikers, golfers and urbanites alike.
Global positioning systems use various satellites, which send microwave signals to the earth, in order to determine the location, time and velocity of the waves. With size and cost constraints, no GPS receiver does it all. However, many GPS users feel that what they can do is pretty cool.
You will have to decide which one you want, depending on your needs, since once you a buy a GPS receiver, you're also buying into its capabilities.
