摘要:
目前,航海用惯性导航系统普遍采用常规的当地水平固定指北机械编排,不适合极区工作,为了满足航海导航的需要,研究了极区惯性导航技术。给出了常规机械编排在极区导航中面临的主要问题,阐述了国内外极区惯性导航系统的发展与现状,分别介绍了自由方位、游移方位、格网及横坐标惯性导航系统的机械编排,并分析了它们存在的问题,最后简要给出了未来极区导航技术研究的发展方向。

Abstract:
Generally speaking, the marine inertial navigation system adopts the local-lever north-direction mechanism, but it does not work in polar region. It is necessary to study an inertial navigation technology in polar region to meet the needs of marine navigation. This paper gives the main problems with the common mechanism used in polar region and presents the domestic and overseas development of inertial navigation in polar region. We also introduce the mechanisms and shortcomings of these kinds of the inertial navigation systems including the free-azimuth inertial navigation system, wander-azimuth inertial navigation, grid-frame inertial navigation and transverse-frame inertial navigation. Finally we list the future development about polar inertial navigation technologies.
Key words:  Inertial navigation system  Polar navigation  Mechanism
