Vehicle Tracking System

Vehicle tracking systems involve the installation of an electronic device in a vehicle or fleet of vehicles, with purpose-designed computer software at least at one operational base to enable the owner or a third party to track the vehicle's location, collect data in the process from the field and deliver it to the base of operation.




Modern vehicle tracking systems commonly use GPS or GLONASS technology for locating a vehicle. Vehicle information can be viewed on electronic maps integrated into the application at the operational base via the Internet or specialized software.



Types of Vehicle Tracking systems

• Passive tracking – "Passive" systems have devices that store GPS location, speed, heading and sometimes a trigger event such as key on/off, door open/closed. Once the vehicle returns to a predetermined point, the device is removed and the data is downloaded to a computer for evaluation.

• Active tracking – "Active" systems also have devices that collect the same information as passive systems but usually transmit the data in near-real-time via cellular or satellite networks to the operations base for evaluation.



Typical Architecture of a Vehicle Tracking System

Major constituents of the GPS based tracking are

1. GPS tracking device: The device fits into the vehicle and captures the GPS location information and other information such as fuel amount, engine temperature, altitude etc. Capabilities of these devices actually decide the final capability of the whole tracking system. These devices also have the ability to transmit the captured information to the operational base (only in Active systems).

2. GPS tracking server: The tracking server has three responsibilities: receiving data from the GPS tracking unit, securely storing it and serving this information on demand to the user.

3. User interface: The UI determines how one will be able to access information, view vehicle data, and elicit important details from it.



Common usage

Vehicle tracking systems are commonly used by fleet operators for fleet management functions such as fleet tracking, routing, dispatch, on-board information and security. Along with commercial fleet operators, urban transit agencies use the technology for a number of purposes, including monitoring schedule adherence of buses in service, triggering changes of buses' destination sign displays at the end of the line and triggering pre-recorded announcements for passengers.

Other applications include monitoring driving behavior, such as a parent with a teen driver.

Vehicle tracking systems are also popular in consumer vehicles as a theft prevention and retrieval device.

Some vehicle tracking systems integrate several security systems, for example by sending an automatic alert to a phone or email if an alarm is triggered or the vehicle is moved without authorization, or when it leaves or enters a geofence.
