SINS误差建模方法及其关系研究

Study on SINS error modeling methods and their relations

通过SINS导航系统误差模型在相同参考坐标系下不同数学形式表示的误差方程,以及相同数学形式表示的系统误差模型方程在不同参考坐标系间的转换关系,针对t-坐标系和c-坐标系推理不同数学表示形式的导系统误差模型,得出各种SINS系统误差模型的适用范围及条件.该结果对SINS系统误差建模具有一定的指导意义.

The article based on the detailed overview of SINS inertial navigation system error modeling method, discussed SINS different mathematical error equations in the same reference coordinate system, and the conversion of the different forms of SINS mathematical model of systematic error equation referring to the reference coordinate system for t -coordinate system and c -coordinate system were detailedly discussed. The different forms of mathematics of SINS navigation system error model was reasoned, and final- ly analyzed the application scope and conditions of the various SINS systems error models was analyzed. The research results on the SINS system error modeling have an important guidance significance.
