A vehicle tracking system is an electronic device installed in a vehicle to enable the owner or a third party to track the vehicle's location. Most modern vehicle tracking systems use Global Positioning System or GPS. The Global Positioning System is a global navigation satellite system developed by the United States Department of Defense and managed by the United States Air Force 50th Space Wing. Many systems also combine a communications component such as cellular or satellite transmitters to communicate the vehicle’s location to a remote user. How GPS Vehicle Tracking works GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the vehicle's exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is? Now, with distance measurements from a few more satellites, the receiver can determine the vehicle's position and display it on the unit's electronic map. There are saveral reasons for why service companies purchase a GPS Vehicle Tracking Fleet Management System. * Aide and assist in dispatch to calls. * Have an accurate method of billing for calls. * Better customer service, "where is the tech". * Eliminate time theft / virtual time card. * Eliminate side jobs and after hour use. * Lower insurance cost. * Make more service calls per day. * Eliminate disputes between customers and mobile workers. * Keep track of vehicle maintenance. * More efficient business / lower costs - raise revenue.
