A network of orbiting geosynchronous satellites enable a GPS tracking system to pinpoint the location of a range of objects and people, with accuracy to within a few feet. As with many technological developments, GPS tracking was first used by the military to find targets and to navigate. Recently, the cost of GPS systems has decreased significantly, and the military has suspended degradations to the signals, thereby making GPS tracking systems available for civilians to utilize.

The technology of GPS has been of great benefit to companies for keeping track of the vehicles within their fleets and also providing a way for drivers to be more efficient in making deliveries and estimating time of delivery. GPS tracking systems for vehicles have even been useful for finding the best way for drivers to get to their locations.

One of the negatives that has come about more recently is invasion of privacy. As these devices are used more and more frequently in our lives, they will continue to present these challenges. Truck drivers were among the first to be tracked and their movements are now analyzed as well. Spies have long known that GPS tracking can be very effective in tracking the movement of individuals.

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.

The miniaturization of Global Positioning Services has created a new component for auto owners, the GPS receiver. The driver can now find their exact location, get turn-by-turn directions, and have it delivered by voice. The days of folding or flipping maps are gone. New innovations include the ability to locate the nearest rest stop, dining establishment, bed and breakfast, or fueling station.

The use of GPS for various purposes will likely increase as the cost of devices continues to decrease. GPS technology is very flexible and can serve as a replacement for current technologies such as paper maps, and may play a role in future advances. Perhaps in the future GPS tracking will allow us to know the location of all of our possessions at all time, making theft and loss a thing of the past.

Satellites allow GPS units to locate and track objects and people. GPS was first used by the United States military for targeting and navigation. Accuracy of the GPS signal for the general public has improved since the military stopped degrading the signal available to civilians. Delivery companies make widespread use of GPS vehicle tracking systems for scheduling and route efficiency. In private automobiles, GPS tracking systems simplify navigation. Outdoor enthusiasts have made GPS devices common in recreational pursuits. "Geocaching" is a hobby that uses a GPS tracking device to find hidden treasures. As prices drop, the use of the GPS system will continue to render older methods of navigation obsolete.
