    b) the absolute direction of the vehicle at a second instant is determined using external auxiliary means;

    c) the difference between the absolute directions is ascertained;

    d) the result of the integration is normalized to this difference; and

    e) a new scaling factor is ascertained from a previously used scaling factor by using the difference between the absolute directions and the result of the integration.
