摘要
分析了传统水下导航定位方法的局限,研究了基于ICCP的水下地磁自主导航算法。首先,研究了局域地磁场建模方法,认为多面函数构建局域地磁场模型较优;然后,研究了ICCP地磁导航算法,并对其作了改进;最后,以所建立的局域地磁场模型为背景,进行了地磁匹配算法的仿真实验,给出了该算法的精度指标及影响因素。
Abstract： underwater geo- magnetic navigation method based on ICCP technique in detail. By the analysis in theory and the comparison in real applications, we get an optimum model, which is multi-curve function model and can improve efficiently the accuracy of building geomagnetic field model. Then, we study the technique of interactive cosest contour point （ICCP） in theory and give out a completed procedure for geomagnetic navigation. In order to make the method strong practicability, we also analyze the factors, which influence the accuracy of underwater geomagnetic navigation. Finally, we give out conclusions and a lot of suggestions.
