GPS tracking systems use satellites that are in a geosynchronous orbit around the earth to determine exact locations of objects or individuals to within several feet of resolution. GPS was originally used for assisting in locating military targets and also for navigation purposes. Recently, as the price of GPS technology has come down, civilian use has increased and accuracy has increase as well since the military no longer degrades the signal.

GPS vehicle tracking systems have been invaluable to companies who need to keep track of their vehicle fleets, while simultaneously allowing their drivers to use the devices to make deliveries more efficiently, and allowing estimation of time of arrival. GPS vehicle tracking systems have also allowed delivery companies to determine the most efficient route for their drivers to take.

There are those, however, who warn of a possible negative effect of using a GPS system, viewing it as constituting an erosion of privacy. Some taxi, truck, and limo drivers are already having their trips scrutinized in this way. On the positive side, GPS technology has proven effectiveness as a means of tracking would-be terrorists, and has been used for some time by federal agents.

GPS has also made significant inroads into the consumer market, allowing individuals to use GPS to lay out waypoints for hikes, set locations for camping or fishing, and allow individuals to navigate in unfamiliar territory. A new form of recreation called "geocaching" has also developed, involving a hide-and-seek game involving a container and a set of latitude and longitude coordinates.

A new and highly desirable automobile add-on is the GPS tracking system. Located in the dashboard, the GPS receiver eliminates the awkwardness of trying to read a map while driving by processing a driver's location request and giving spoken or visual directions. Other useful features are now being added to these devices, such as information on restaurants and hotels.

Usage of GPS technology is very likely to become more prevalent as the price of the devices continues to decrease. The ubiquity of GPS in today's world may render older technologies such as paper maps, obsolete. GPS systems may also serve as a springboard for future technological developments, such as property theft deterrence, by being able to track at all times all of one's possessions.
