摘要
以九加速度计的惯性测量单元为例,介绍了无陀螺捷联惯性导航系统(GFSINS)的工作原理;对GF-SINS/GPS组合导航系统选择滤波器问题进行了理论分析,提出了基于自适应滤波器的组合方法;该方法通过在线联合估计噪声统计特性和系统状态,有效地解决了GFSINS/GPS采用间接法组合时,无法得到准确系统噪声统计特性的问题。通过仿真验证了该方法的有效性。
This paper introduces the work principle of GFSINS by using an example of ninth-accelerator configuration.This paper proposes the self-adapting filter＇s base integrated method by carrying out the theory analysis of the chosen filter of GFSINS/GPS.Indirect method integrated can＇t get noise static character exactly.This method solves above problem effectively by estimation of noise static character and system vector at real-time.The simulation experiment shows the effectiveness of this method.
