1. An automated positioning system for determining an angular deviation of a vehicle from a predetermined path, the system comprising:
- an electro-optical sensor onboard the vehicle for detecting two beams that scan across at least a sector of interest in opposite directions and that are synchronized with each-other so as to substantially overlap in the direction of the predetermined path, said two beams originating from known positions relative to the predetermined path; and
a logic circuitry on board the vehicle for determining a difference in time of detection of said two beams, the difference in time being indicative of the angular deviation.

Abstract
A positioning system for determining an angular position of a vehicle (10) with respect to a predetermined position. The system comprises at least one beacon (12) whose position relative to the predetermined position is known, for generating at least one beam of known optical characteristic that allows deriving of the angular position.

16. An automated positioning method for determining an angular deviation of a vehicle from a predetermined path, using two beams sweeping across at least a sector of interest in opposite directions and being synchronized so as to substantially overlap in the direction of the predetermined path, each beam of said two beams originating from a known position relative to the predetermined path, the method comprising:
-
detecting by an electro-optical sensor onboard the vehicle of said two beams; and processing by a logic circuitry on board the vehicle of signals generated by the sensor so as to determine a difference in time of detection of said two beams and processing the difference so as to determine the angular deviation. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
