Shipping and transport companies use vehicle tracking systems to be able to know the location of a group of vehicles. Courier companies utilize vehicle tracking systems to locate and know the status of a shipment. Taxi companies need vehicle tracking systems to locate units and assign them the nearest passenger needing their service.

Sometime ago, vehicle tracking systems were only made available for use in expensive cars, so that once a car theft occurs, the vehicle can be located easily and thus retrieved.

Because vehicle tracking systems have evolved and now have made its place in the market, many other forms of systems are available and can be purchased by the average consumer.

There are GPS vehicle tracking systems that can be installed in your vehicle to find its exact position from anywhere in the United States at your convenience. Some GPS vehicle tracking systems go as far as to record the places the car has been to, how far the vehicle has traveled and how long the vehicle stayed in a certain location.

There are three things required to make vehicle tracking systems work: a transponder unit containing a GPS receiver and wireless radio, is attached on the vehicle; a form of communication to transmit the data of the vehicle and a user interface where one views the results in a certain format. Vehicle tracking systems use GPS satellite technology whose satellite operates above the earth. The satellite is the main instrument that sends the time and location of the vehicle.

Wireless networks use real time software to obtain the information on location, speed and other data of the vehicle. The request is communicated to the transponder; it responds with the pertinent location data and sends it back to the wireless network provider. The wireless network then communicates the information to the vehicle owner using real time tracking software. The consumer views the result via desktop, Internet or even cell phone.

Vehicle tracking systems have been responsible for increased productivity, improvement in dispatching and a decrease in the maintenance costs of the vehicle. There is also a better system in planning the usage of vehicles in a transport, shipping or courier company so as to save time, gas and effort by not going to the same place in one time.
