本文介绍一种分析捷联式惯性导航系统(SINS)导航性能的新方法，说明了该方法的思路，着重分析了该方法的关键——如何根据假定的载体运动轨迹推导出相应的加速度计及陀螺仪的理想值fb及ωbib，并给出了几种典型运动状态下获取fb及ωbib理想值的方法。文中还以载体处于静止状态及摇摆状态为例，用所述方法对SINS的导航性能进行了具体分析。

A new method of analyzing the navigation performance ofSINS(Strap-down Inertial Navigation System)is introduced in this paper.Because the determination of the theoretical values of fb and ωbib(the outputs of accelerators and gyros of SINS)according to the assumed movements of the body is the key to using this new method the procedure of determining these values is discussed with emphasis.The way of obtaining theoretical fb and ωbib of SINS being in some typical movements is discussed also.As examples the new method is used to analyze the navigation performance of SINS being in the static state and the swing state in the paper.
