Paper Abstract

Terrain contour matching (TERCOM) algorithm is the main one in the conventional terrain aided navigation system. When it has been directly applied to the submarine terrain aided navigation (STAN) system, the accuracy and stability are primely reduced. To solve these problems, the detail analyses about the particularities of the STAN and the disadvantages of the conventional TERCOM algorithm have been made. The improvement for the TERCOM algorithm on the measurement function, the water depth survey error and the scheme to prevent fail positioning has been done. Moreover, experiments with pedestrian simulation confirm the effectiveness of the improved TERCOM algorithm. The system achieves higher positioning precision than that of conventional one.
