ABSTRACT:
A vehicle navigation system automatically corrects the coefficient of its velocity sensor with high precision. This system obtains a distance between two positions measured by a GPS and a linear travel distance calculated on the basis of the signals outputted by the velocity sensor during a period between the measurement of the two positions. Then, the system corrects the velocity sensor coefficient so that the linear travel distance becomes equal to the distance between the two positions.
