摘要
惯性导航误差是随时间积累的,利用重力匹配进行水下辅助导航,可以对惯性导航的漂移误差进行校正。本文主要研究ICCP算法在重力匹配辅助导航中的应用,通过理论分析和试验证明ICCP方法在初始位置误差不大的条件下,可以实现高精度的匹配,这种算法具有局部最优性。
Gravity anomaly data can be used to correct the drifting errors in the inertial navigation of submarine which are accumulated over time. This paper introduces the new matching algorithm Iterative Closest Contour Point（ICCP） and its application to gravity matching. After analysis and experiments, it can be concluded that the matching result can reach high precision if the initial position error is not large. This algorithm has the best performance locally.
