Nothing can be more complicated and full of hassles for fleet managers than keeping eye on moving vehicles and the errant behavior of drivers. It is really a difficult task to keep eye on moving vehicles and at the same time get real time information about vehicle maintenance and mileage. If you are also one the fleet managers who really faces such problems, then installation of high end vehicle tracking devices would surely be the best option for you. GPS vehicle tracking systems are s the best way of tracking vehicles or follow employees suspected of malingering.
As far as the working process of vehicle tracking systems are concerned, they work according to GPS or The Global Positioning System that is a satellite based navigation system made up of 24 main satellites orbiting the Earth and transmitting radio-wave signals to earth. The waves are used through GPS receiver to track and calculate exact location of moving vehicles or anything else in which a GPS vehicle tracking device is installed. Innovative vehicle tracking devices come equipped with GPS receiver that helps in finding out the exact location of vehicles by calculating the time and distance each satellite from that information.
When the distance is estimated to different satellites (at least last four), the location of the moving vehicles is calculated by the receiver and the details are saved in the servers installed in service providers workplaces. Interest fact is that you can get real time information without installing any software or any other tool. What all you need to have to get real time information is an Internet connection and web browser according to your preference.
