Observability's Comprehensive Analysis of Inertial Navigation System
Author(s): 
Pages: 14-19
Year: Issue:  3
Journal: AEROSPACE CONTROL

Keyword:  惯导导航可观测性初始对准卡尔曼滤波;
Abstract: 应用线性控制系统的结构分解理论及奇异值分解法对惯导系统(INS)初始对准过程中的可观测性进行了全面分析,深入研究和详细分析了各种状态组合对系统可观测性的影响,定量地得出了惯导系统最佳观测状态组合时的结构分解过程及最佳可观测的子系统,为进一步研究INS的快速精确对准方法奠定了理论基础.
