Optimal selection and adaptability analysis of matching area for terrain aided navigation

Abstract The existing terrain aided navigation (TAN) has the disadvantage that the navigation performance is limited by the size of matching area and terrain features. Therefore, this study proposes a method of optimal selection and adaptability analysis of matching area for TAN. According to the he...

According to the heading angle of the carrier, inertial navigation system positioning error and performance index, the optimal matching area is selected in real time.
