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.
There's nothing like GPS tracking systems for keeping tabs on a company's motorized assets. Not only do such systems help optimize drivers' delivery performance, it also makes estimating delivery times far more accurate. These global positioning systems also make it possible to map out the best routes to maximize driver efficiency.
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 become a consumer tool as well; several new tools allow laymen to use GPS systems to plan hikes, find locations for fishing or camping, and find their way around unfamiliar places. Commercial GPS devices have given rise to "geocaching," a pastime where participants search for hidden items using their latitude and longitude coordinates.
GPS tracking systems can now be purchased from an automotive dealer as an additional feature to a new car. They can be mounted directly into the dash of the car for easy access to the driver. These devices provide searches which include restaurant and hotel mapping. It is nearly impossible to get lost with one of these devices in the car.
GPS devices are likely to become increasingly common as the cost of GPS devices decreases. GPS technology is quite flexible, and it is not difficult to envision it completely replacing current technologies such as paper maps. Nor is it difficult to imagine it playing an important role in new technologies. Who knows, perhaps one day GPS tracking will make loss and theft a thing of the past by providing real time information about the location of all our possessions.
