Abstract:
A method of real time guiding a vehicle in adjacent swaths across terrain that may slope by using an optimum trajectory, said method comprising the steps of:(A) determining in real GPS time the position with respect to Earth of a predetermined location that is fixed relative to the vehicle; (B) synchronizing said position measurements performed in said step (A) with a GPS clock; (C) determining the tilt of the vehicle with respect to Earth due to a slope of the terrain; (D) synchronizing said tilt measurements performed in said step (C) with said GPS clock; and (E) using the tilt and position determinations to provide information in real time synchronized with said GPS clock for guiding the vehicle by using said optimum trajectory to prevent gaps and overlaps between adjacent swaths as the slope changes.
