Abstract

A method for aircraft navigation which includes, sensor signal processing with refernce data. The method provides for sensing and range finding the elevational profile underneath the craft. Those elevational data are fed to a segmentizing and type classifying unit whose output in turn is fed to a classifying unit, and that the position of the craft is determined by comparing the segmentized overflight strip with corresponding topographic features in reference information.
