Abstract
In a navigation system with a magnetic field sensor (2), installed in a vehicle, for determining direction and with additionally available location data, an angular installation error of the magnetic field sensor is determined in the following manner: the difference is formed from the measured actual value of the direction and the nominal value determined from known location data for the direction and is stored in accordance with the direction of the nominal value, in an associated sector memory, forming the mean value. If the mean values in all sector memories significantly correspond to one another, a total mean value is formed from the mean values and is used as the rotation error for correcting the direction measurement. <IMAGE>
