ABSTRACT:
Navigation apparatus in accordance with the invention uses a Large Reference/Small Scene approach in which a plurality of small scene areas are obtained by viewing the surroundings of a moving object and are compared together with a large reference area to produce a match between them, and hence give an indication of the position of the object with respect to the reference area. The apparatus utilises the fact that the small scene areas are in a known distribution and correlation maxima should be found having that distribution, other maxima being effectively randomly distributed.
