A method of steering a vehicle along a predetermined, or real time path by
using a steering control algorithm. The vehicle includes a navigation
system and a navigation antenna. The navigation antenna is mounted on the
vehicle at an optimum antenna position, whereas the steering control
algorithm assumes a nominal antenna position at a predetermined reference
point. The method comprises the following steps: (A) obtaining a set of
positioning data of the vehicle by using the navigation system and by
using the navigation antenna mounted at the optimum antenna position; (B)
modifying the set of positioning data of the vehicle; (C) measuring a
steering angle(s) of the front wheels of the vehicle relative to a
predetermined reference direction(s); (D) calculating a correction(s) to
the measured steering angle(s); and (E) performing a steering action by
using the correction(s) to the measured steering angle(s) to move the
vehicle along the predetermined, or real time path.
