Zusammenfassung:	A positioning system having an onboard positioning device and a roadside device is provided. The onboard positioning device receives a plurality of first positioning signals and records a positioning moving locus of a vehicle according to the first positioning signals. The roadside device detects a real moving locus of the vehicle. The onboard positioning device obtains the real moving locus from the roadside device, and calculates a positioning calibration value according to coordinates of the positioning moving locus and coordinates of the real moving locus. Furthermore, the onboard positioning device receives a plurality of second positioning signals and calculates and outputs a plurality of calibrated positioning coordinates according to the second positioning signals and the positioning calibration value.
