Abstract:
1. A guidance system for a vehicle comprising a laser source directing at least one laser beam towards a required designated final location for the vehicle on which at least one sensor is located, that sensor rotating around an axis in a direction of travel of the vehicle and having a field-of-view (FOV) that is generally directed sideways to the direction of travel of the vehicle, the sensor generating a pulse signal in response to detecting radiation from the laser beam scattered by an atmosphere through which the laser beam propagates, the pulse signal having a number of pulses proportional to the distance between the beam and said vehicle, signals from said at least one sensor being applied to a vehicle guidance system in the vehicle having processing electronics that determines the distance from the vehicle to the beam and then provides correction commands to the guidance system to correct the vehicle's direction of travel.
