地磁导航是一种根据地磁场磁要素信息进行匹配制导的重要导航方式,由于地磁场信息丰富、敏感,利于匹配,且没有累积误差等优势,目前,地磁导航正受到越来越多的关注。本文简要介绍了地磁导航的基本原理,结合国内外导航研究现状,重点介绍了地磁导航的多项关键技术研究进展情况,最后对地磁导航在未来国防建设发展中的应用进行了展望。
Geomagnetic navigation is an important navigation technique by using geomagnetic feature. It has advantage of abundant geomagnetic information for matching,no accumulative error and so on. Thus the geomagnetic navigation is receiving more and more attention. In this paper, the geomagnetic theory is introduced briefly; the research history of geomagnetic key technique is reviewed. Finally, the development and application of geomagnetic navigation in national defense is forecasted in the future.
