New trends in Vehicle Tracking using GPS

March 2, 2009 - PRLog -- There are two types of GPS Tracking systems: A comparison

Active GPS Tracking system: An active GPS tracking system is a real-time system that uses GPS and a cellular network to collect real time data wherever it is deployed. Active tracking is intended to show a vehicles current physical location.

Normally, active tracking can be quite expensive, since these systems use the satellite network to track and use of the air time on satellite networks can be expensive. Various solutions to this have been created, such as calling in the position when the vehicle deviates from a pre-planned route. This requires that the device be pre-programmed with the route, however. Also,  satellite-based systems do not work inside buildings.
Apart from our technological advancement new products from GPS have arrived in the market. Everything works using the GSM network, so it will work within buildings and anywhere where there is sufficient GSM coverage. That covers a very wide area indeed!

Passive GPS Tracking system: A passive GPS tracking system is used where real-time data is not required, but records need to be maintained. Passive tracking is used to tell where a vehicle has been over a certain period of time.  

A vehicle tracking system can produce individual vehicle data like spacing, headway, velocity, and acceleration. This helps to better traffic flow modeling and a better understanding of driver behavior. The  auto tracking system is also one of the biggest advancements in car security.  

Automatic vehicle location can be applied to various scenarios:
1. Stolen Vehicle recovery
2. Fleet management
3. Passenger information
4. Asset tracking
5.Field worker management
6.Covert surveillance
