If the general differential GPS technology is used, each vehicle shall receive the differential correction number, which will cause the system to be too complex, so the centralized differential technology is often used in practical applications.
Working principle: Each vehicle is equipped with GPS receiver and communication radio. The monitoring center is located at the base station, and the coordinates are known accurately. GPS receiver is installed on the reference point, and communication radio, computer, electronic map, large screen display and other equipment are installed at the same time. When working, the GPS receiver on each vehicle sends its position, time, vehicle number and other information to the monitoring center. The monitoring center calculates the difference between the vehicle position and the GPS positioning result of the reference station, corrects the vehicle position, calculates the precise coordinates, and displays them on the large screen after coordinate conversion.
This centralized difference technology can simplify the equipment on the vehicle. The on-board part only receives GPS signals, and does not need to consider the reception of differential signals. The monitoring center centralizes differential processing, display, record and storage. The original vehicle communication equipment can be used for data communication, as long as the communication conversion interface is added.
As the differential GPS equipment can provide accurate position, speed, heading and other information in real time, the on-board GPS differential equipment can also calibrate various sensors on the vehicle (such as log, speedometer, magnetic compass, etc.).
