Abstract
A location system for a motor vehicle in which the calibration of a displacement sensor is performed with the aid of satellite signals. A Global Positioning System (GPS) receiver may be used, and the current vehicle speed within a time segment is calculated using the Doppler method. The distance traveled is ascertained from the vehicle speed. By taking a mean, calculating the dispersion, and performing a weighting, a very accurate reference value for calibration of the displacement sensor is achieved.
