First of all there is a need to know about the GPS (Global Positioning System) through which the vehicle tracking is made much simpler. GPS is nothing but a system where you can know the position and time of an object using the Global navigation satellite system. It is a group of satellites which receive signals from the GPS transmitters and sends data to the receivers. The GPS thus enables you to know the exact location, speed, events like opening/closing of doors, fuel levels and much more data regarding your vehicle when your vehicle has a GPS unit.
There are different types of vehicle tracking systems. Passive tracking involves the devices which store data and needs to be removed and fed on to a computer system for downloading the data and analyzing. Whereas active tracking involves devices which receive similar data but transfer them on real-time basis through cellular or satellite modes. Few transmitters can work both ways; when there is cellular network available, they act as active devices and when it’s not available they act as a passive device. They can also be categorized as analog and digital devices based on the type of signal used to communicate.
The components in a vehicle tracking system mainly involves a GPS tracking device (transmitter) which is fitted inside the vehicle where it can’t be easily detected by the vehicle thief and hence can’t be deactivated easily. The GPS transmitter sends signals continuously to the monitoring station. Next is the GPS server which takes care of the data/signal reception, stores it securely and provides the data when asked for. Finally the GPS interface or the control system is the one which triggers the alarm that the vehicle has been stolen and immediately facilitates the tracking process.
This GPS interface can be operated through mobile phone technologies like an SMS or an alert call and so on. When you notice that your vehicle has been stolen, immediately SMS the required code to the required number. This results in switching on the alarm and thereby the security agencies can access details like the location, speed etc through the GPS server and can track the vehicle.
Few advanced vehicle tracking systems off late have been capable enough of operating vehicle controls like door lock, engine on/off, fuel switch, steering lock and even brake and clutch. This can render the thief with very few options. Sometimes they are also enabled to send automatic signals to the pre destined cellular numbers when found operated by unauthorized persons.

Vehicle tracking systems can be operated through cellular networks or satellite group networks. Few global vehicle manufacturers have incorporated their own built-in devices in their vehicles and give their customers the choice of subscription to the service. They have also incorporated other features like automatic crash response systems, in-built navigation helper etc by using the same technology.
The vehicle security is greatly increased with these tracking devices through mobile phone technologies and at the same time note that the theft insurance value of your vehicle is greatly reduced. Nevertheless it is always worth having a vehicle tracking system to provide an unparalleled security to your vehicle.
