摘要/Abstract

摘要： 从理论上完善极区格网惯性力学编排方案,并对SINS/GPS组合导航系统工作在中低纬度与极区的环境下进行仿真,为基于格网框架的极区惯性组合导航提供理论支撑。仿真结果表明：SINS/GPS组合导航系统能够较好的克服SINS和GPS各自的缺点,明显的提高工作性能,通过仿真结果比较,可以得到基于格网框架的极区SINS/GPS组合导航方案的导航精度同中低纬度地区组合导航方案一致,验证了极区SINS/GPS组合导航方案的有效性。

Abstract: The mechanics equations of grid navigation system are improved and analyzed in the paper. It is simulated that the SINS/GPS Integrated Navigation System works in the low latitude region and the polar regions. The theoretic is supported by the research of the SINS/GPS Integrated Navigation System working in the polar regions. The result of simulation shows that the performance of SINS/GPS Integrated Navigation System is improved and the shortcomings of SINS and GPS are avoided. By comparing the simulation results of the SINS/GPS Integrated Navigation System, the navigation precision is consistent when the SINS/GPS Integrated Navigation System works in the low latitude region and the polar regions, which verifies the effectiveness of the SINS/GPS Integrated Navigation System working in the polar regions.

Key words: Grid Reference Frame, SINS/GPS integrated navigation, transpolar navigation, global navigation, polar regions
