The Underwater Gravity Matching Navigation Adaptation Area Is Preferred Based on The Multi-Starting Point TERCOM Algorithm

This paper focuses on the selection of matching area in gravity matching navigation system of underwater submersible. To solve the adaptation of the study region by using the TERCOM algorithm, this paper proposes the trajectory matching with three equal starting points within the study area. The experimental results show that this method can divide the adaptation area of the study area more comprehensively.
