The invention relates to a method which is based on the technology of
satellite differential positioning and inertial navigation, employs the data fusion and
wireless bandwidth data communication, and achieves the precise positioning of a vehicle. The invention aims at effectively integrating various types of positioning navigation technologies, the data fusion and the
wireless bandwidth data communication into a seamless
positioning system suitable for intelligent traffic, providing real-time stable continuous position information for a sub-meter level to a
centimeter level for a running vehicle, and achieving the lane-level positioning navigation of the vehicle. The technical scheme of the invention is that the method employs a reference
station and a moving terminal, wherein the reference
station is installed nearby a road, and consists of a
satellite receiver of the reference
station and a
wireless bandwidth data communication module; the data is transmitted according to the demands of the moving terminal; the moving terminal is disposed on the vehicle, consists of the
wireless bandwidth data communication module and a combined
positioning system, can actively visit a plurality of reference stations for obtaining data to complete the multi-base-station differential positioning, and also can adjust the updating frequency of
data transmission in real time.
