| 摘 要： | 针对基于点的地磁匹配导航算法一次定位时间太长,不能满足导航系统对实时性的要求的缺点,提出基于向量的地磁匹配导航算法,满足导航系统对实时性的要求.基于点的地磁匹配导航算法和基于向量的地磁匹配导航算法都是基于单点的匹配算法,这决定了它们有共同的缺陷:匹配结果可能不唯一.针对这一点提出基于Monte Carlo的地磁匹配导航...

| Abstract: | Geomagnetic Matching Navigation Algorithm(GMNA) is an important factor to influence the navigation precision,to some extent GMNA determines the navigation precision.An excellent GMNA not only fulfils the precision demand but also the time.First,in this paper GMNA based on point is studied,which is unsatisfied with the real-time due to the long time of position.Addressed to the problem which exists in GMNA based on point,GMNA based on the vector is proposed,which is satisfied with the real-time needed to the... |
