Abstract
An orientation and navigation device provides for a current vehicle position to be displayed on a map. To make corrections in the event of loss of orientation, a satellite receiver is employed, which calculates a new vehicle position from the received satellite data and bases the dead reckoning on this new vehicle position. Since the calculated satellite orientation position is encumbered with a variation range, an optimization is performed by means of a low-pass filter and empirically determined values.
