ABSTRACT:
A method and apparatus for navigation of a vehicle travelling over a terrain in which the changes in elevation of the vehicle are continuously measured, in addition to the distance and heading. The distance measurements are continuously corrected by the changes in elevation in determining the instantaneous location of the vehicle with respect to a known point. The approximate location can also be obtained from a satellite GPS (global positioning system). The measured elevation may also be compared with the elevation in reference data, such as data in a three-dimensional map of the area to prevent the accumulation of errors or to make the determined location more precise.
