Caterpillar, Sterne Kessler Goldstein & Fox, March 11, 1997: US05610815 (321 worldwide citation)

A system (400) for positioning and navigating an autonomous vehicle (310) allows the vehicle (310) to travel between locations. Position information (432) is derived from global positioning system satellites (200, 202, 204, and 206) or other sources (624) when the satellites (200, 202, 204, and 206) ...
