Summary:PCT No. PCT/FI95/00253 Sec. 371 Date Jan. 22, 1997 Sec. 102(e) Date Jan. 22, 1997 PCT Filed May 12, 1995 PCT Pub. No. WO95/31759 PCT Pub. Date Nov. 23, 1995The invention relates to an autonomous navigation system for an unmanned vehicle. The tracks or wheels are driven by hydraulic reversible motors, having the output thereof regulated by valves whose relative control can be used for controlling both heading and speed. The vehicle carries a navigation computer which receives positional information from an external positioning sytems. A ground station computer has been supplied with a digitized map over a predetermined path and the ground station computer is in a two-way radio communication with the vehicle navigation computer which is supplied with the information relating to the path. An established path, which is received from the external positioning system, is compared to the predetermined path and the vehicle navigation is modified for compensating the deviations.
