捷联惯性导航系统安装误差分析

捷联惯性导航系统（SINS）现已广泛装备于各类载体上,但由于惯性测量装置直接安装在载体上,安装误差的存在会影响惯性器件的输出,进而影响系统的导航精度。因此对捷联惯性导航系统安装误差进行分析,对于减小惯性器件输出误差,提高载体的定位精度具有极其重要的作用。对捷联惯性导航系统主要误差模型进行深入分析的基础上,对惯性器件的两类主要误差影响进行了分析讨论,并通过仿真试验对分析结果进行了验证。

Research on Installation Error in SINS

The Jie allied inertial navigation system（SINS） has already been widely used in all kinds of vectors.Because of the inertial diagraph the direct gearing is in carrying a body,the existence installing an error margin will influence the exportation of inertial spare part and then influence navigating of system accuracy.Consequently unite inertial navigation system to the Jie gearing the error margin carry on analysis,for let up the inertial spare part exportation error margin,exaltation carry the fixed position accuracy of body to have the function of very importance.This text is allied the inertial foundation of navigation system main error margin model is in the thorough analysis Jie up,carried on an analysis discussion to two types of main error margin influence of inertial spare part,and pass to imitate to really experiment to analysis carried on a verification as a result.
