Abstract

The invention relates to a navigation system for determining the course of a vehicle. Said navigation system comprises a main sensor system (10) for measuring the status variables describing the vehicle state, an auxiliary sensor system (20) that comprises at least one sensor for measuring an additional status variable, and a navigation core (15) that estimates error-minimized status variables on the basis of the measured status variables. The navigation core (15), in order to achieve a higher generality and robustness with regard to sensor errors of the system, comprises a vehicle model (16) that predicts, on the basis of the measured data of the main sensor system (10), the status variables of the vehicle. The navigation core further includes an error estimator (17) for predicting the errors of estimation made by the vehicle model (16), and a correction element (18) that corrects the predicted status variables by means of the predicted errors of estimation.
