Abstract
The iterated closest contour point(ICCP) matching algorithm based on Fibonacci number series was proposed.The improved ICCP matching algorithm was also presented because of its confinement to the real track near the INS track.The INS track was corrected based on correlative extremum at first,then ICCP matching was made in order to further improve the accuracy.By analyzing the data within experimental area under different simulative conditions,the results show that all navigation errors were corrected effectively.
