Vehicle tracking works by using GPS satellite communication with the receiver unit in your vehicle. The Global Positioning System (GPS) is made possible by a group of satellites in orbit around the earth orbit that transmit signals, allowing GPS receivers to calculate and display accurate vehicle’s location, speed, and time information to the user.
Data Processing and Storage
With the addition of computing power, and data stored in memory such as road maps, points of interest, topographic information, and much more, GPS receivers are able to convert location, speed, and time information into a useful display format. GPS data may also be fed to a website for real-time location mapping.
GPS tracking takes the normal functions of a GPS device a step further, by either capturing and storing position data within internal memory for retrieval later, or by transmitting location data in real time via the same cellular data network used by mobile phones.
So, to sum up how a GPS tracker works: It gathers, analyzes, and stores location data from GPS satellite signals, processes the location information, then saves it for review later, or transmits it in real time.
Position of the tracking device within the vehicle
The need to capture satellite signals, and often, to get a signal to the cellular network, means that GPS tracking devices need to have access to the open sky. They don’t work well indoors, or deeply positioned within a vehicle. GPS tracking devices also need a power source. This most often comes in the form of a rechargeable internal lithium-ion battery. But many GPS tracking devices are also powered by tapping into the electrical system of a vehicle.
