Tracking Vehicles and Trucks with GPS

In the recent years, GPS (Global Positioning System) has become very common and is being installed in vehicles for several reasons. Learning the location of a vehicle has become much easier as satellites can track the latitude and longitude of vehicles accurately.

A GPS system makes use of 24 satellites that continue revolving around the planet. Each satellite sends radio signals to the server and contributes towards pinpointing accurate location, speed and direction by calculating latitude, longitude and altitude. The radio signals also transmit the exact time these impulses are observed. Based on its distance from the satellite, the GPS tracking unit evaluates the movement of the vehicle. GPS technology helps vehicle owners and businesses track their vehicles with great accuracy.

GPS tracking systems are divided into passive and active tracking devices. Passive GPS tracking systems for trucks mainly transmit information like roadmaps, fuel consumption, velocity and traveling tracks. Passive tracking devices use short range radio networks to transfer data between each tracking unit and the server. Passive tracking devices are mainly used to download data for future batch processing.

Active GPS tracking systems acquire real time statistics of location and direction of the vehicle. This information is transported through email or fax, allowing the server to identify location in real time. Active tracking systems can provide updates through fax, phone and email. Owing to their real time properties, active GPS systems are more expensive than passive tracking devices.

GPS technology can be applied to vehicles like cars, bikes, buses, trucks and ships. This technology is very helpful for fleet management businesses as they can analyze accurate information on a daily basis and keep track of their activities like travel data, routes, mileage, time of journey etc. GPS is also used by bus companies to ensure that their vehicles are adhering to time constraints and completing their schedules.

GPS is also helpful in preventing theft and plays a pivotal role in retrieving the stolen vehicle. GPS can not only pinpoint the exact location of the vehicle but can also be configured to shut off engines through remote control.
