Inertial navigation and attitude initialization in polar areas become a hot topic in recent years in the navigation community, as the widely-used navigation mechanization of the local level frame encounters the inherent singularity when the latitude approaches 90°. Great endeavors have been devoted to devising novel navigation mechanizations such as the grid or transversal frames. This paper highlights the fact that the common Earth-frame mechanization is sufficiently good to handle the singularity problem in polar areas. Simulation results are reported to demonstrate the singularity problem and the effectiveness of the Earth-frame mechanization.

关于极区的惯性导航和姿态初始化
极地地区的惯性导航和姿态初始化在近年来成为导航界的热门话题,因为当纬度接近90°时,局部水平框架的广泛使用的导航机械遇到固有的奇点。已经致力于设计新颖的导航机械化装置,例如网格或横向框架。本文强调了这样一个事实,即普通的地架机械化足以应付极地地区的奇异性问题。报道了仿真结果,以证明奇异性问题和土架机械化的有效性。
