GPS tracking systems utilize a network of geosynchronous satellites in orbit to determine the location of an object or person down to a few feet resolution. GPS tracking systems were initially deployed to assist the military in locating targets of value as well as in navigation. In recent years, the price of GPS hardware has decreased, while the military has suspended the degradation of the signal, allowing more accurate placement for civilian use.
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.
A potential down-side to increasing use of these devices is the invasion of privacy some see these devices as presenting. Already, commercial drivers have their daily trips catalogued and analyzed. Similarly GPS tracking device technology has already been shown to be effective at allowing the tracking of individuals as these devices have been implemented in espionage for years.
The advent of GPS technology has had an impact on many recreational activities such as hiking, camping and fishing because it allows GPS users to better navigate new areas. Additionally, a new recreational activity has come from GPS itself, an activity called "geocaching." This new activity is something like a game of hide-and-seek using the longitude and latitude coordinates to locate a particular container.
GPS tracking systems have also allowed the development of a new automotive add-on, the in dash GPS receiver allowing consumers to request a location and have the device display or speak directions to the driver, making the paper map obsolete. These devices are already increasing in complexity and adding new features including hotel and restaurant information.
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.
