 The Evolution Of GPS Vehicle Tracking Applications

The present day vehicle tracking is accomplished by using GPS, which is a popularized name for Global Navigation Satellite System. It provides the driver with a highly accurate map, portrayed on a small screen incorporated into the GPS receiver. Here the driver can monitor their present location, plan the best route and obtain an estimate of time to arrival. The Global Navigation Satellite System was developed by the United States and the Soviet Union created its GLONASS during the Cold War to accurately guide their extensive ICBM and SLBM inventories. Later it was used as a backup guidance system for both nations' nuclear submarine fleets.

The current GPS tracking used in vehicles comes to us, in civilianized form courtesy of President Ronald Regan. It was after the tragedy of airline flight KAL 007 that President Regan made it available for civilian use. GPS vehicle tracking allows an uncorrected location accuracy of 3 square meters. The ability for civilian course schedule to receive the p coded military GPS signal occurred after President Clinton authorized its' release in 1996. Today you are able to know within feet and inches the location of your vehicle while on the move.

A GPS vehicle tracking device is composed of three parts; the space segment which is composed of 30 geosynchronous satellites orbiting along six (6) planes, the control segment which is composed of six (6) land based monitoring stations and the user segment which is a radio receiver capable of calculating its precise position from comparing multiple accident avoidance course signals from the satellites. The satellite signal is the output of a satellite's location in coded latitude and longitude and the time. By comparing the signals of many satellites and comparing the time of reception, the receiver can determine its exact location. This calculation is a result of a mathematical process called trilateration.

Today there are smart business applications for the use of GPS vehicle tracking device. One of its applications is in the taxi business. Two separate firms in the United States (Dallas, Texas and Atlanta, Georgia) and one in London, England have used it to california private investigator on their dispatch capability. The dispatcher has a Geographic Information System workstation computer that includes a radio transceiver. This provides them with a map of the city and shows the active location of all taxis. It also shows the dispatcher which taxis are working and those that aren't.
