为研究旋转周期对单轴旋转惯导系统影响,利用拉普拉斯变换求解单轴旋转惯导系统误差方程的方法,分析了单轴旋转惯导系统的误差振荡特性,指出旋转惯导系统振荡误差不仅包括舒拉振荡、傅科振荡和地球振荡,还存在旋转振荡,通过对不同旋转周期条件下系统输出振荡误差幅值的分析,给出较为合适的旋转周期,降低旋转惯导系统的振荡误差,为工程应用上选取合适的旋转周期具有一定的参考价值。

In order to study the influence of rotation period on the single-axial rotation SINS, the error equations of single-axial rotation SINS were solved by Laplace transform, the characteristics of oscillation errors of the SINS were analyzed. It was indicated that the oscillation errors not only contain the Schuler oscillation error, the Foucault oscillation error, the Earth oscillation error, but also the Rotation oscillation error. The more suitable rotation period has been offered by analyzing the oscillation error amplitude in different rotation period, which has certain reference value on engineering application.
