How a Vehicle GPS Tracking System Works
GPS navigation systems are the most innovative technology of 21st century and almost everyone know about its unique features and benefits. But do you know how it works? Here you’ll be explained about the working system of your 3G vehicle GPS tracker, read now.
Do you know GPS network consists of 27 global positioning satellites among them 3 are backup satellites? And these satellites are arranged in a way that four satellites are positioned in each of six orbital planes. Through the GPS receiver in your car, each satellite transmits radio signals. This is done by a mathematical principle called trilateration. In this principle, the GPS receiver must get your location to be traced by at least three satellites circling above. It is also must to know about the distance between those satellites and your location. By comparing the locations of each satellite and its distance from each, and repeating the same again, the GPS tracker configures the direction of travel, speed, location and more.
And if you are using a passive GPS, it will store data and in an active GPS, you’ll get the information as soon as possible, thereby providing real-time information on your vehicle’s activities. 3G GPS tracker can also be used to monitor ignition-based starts and stops, vehicle mileage, excessive idling, aggressive driving and much more. Some trackers even allow locking or unlocking doors, enabling or disabling the starter or even alert you on over speed. So better to have a GPS tracker for vehicle than to be sorry in future.
