We've all heard about GPS, and many of us use GPS receivers to obtain driving directions and to participate in the relatively new pastime of geocaching. GPS often pops up in many primetime hit drama series as a way to track criminals or the movements of police officers in peril, and is used by the military in combat and non-combat operations. But most of us have never considered the peace of mind that comes with installing a GPS vehicle tracking system - and may not even know that a GPS tracking system is available. Here, then, are answers to five commonly asked questions....

GPS stands for Global Positioning System, which is essentially an array of satellites that orbit the Earth at about 11,000 miles above ground.

A receiver can use satellite photos or map overlays as reference points so that the user can interpret the longitudinal and latitudinal data.
