Geodesic-Based Method for Improving Matching Efficiency of Underwater Terrain Matching Navigation
In this study, we improved the matching efficiency of underwater terrain matching navigation. Firstly, a new geodesic-based method was developed by combining the law of the shortest arc in spherical geometry with the theory of the attitude control in space and maritime environments. Secondly, along...
