本文在一般双自旋卫星动力学模型线性分析的基础上,给出了双自旋同步气象卫星姿态稳定度的数学描述和不规律姿态运动(摆动运动、章动运动)对姿态稳定度影响的解析表达式,并与非线性模型数学仿真结果进行对比,表明仿真结果与线性分析结果相当一致。
Based on the linear analysis of the general double-spin satellite dynamics model, this paper presents the mathematical description of the attitude stability of the dual-spin synoptic weather satellite and the influence of the irregular attitude movements (oscillatory motion and nutation motion) on the attitude stability The expression is analyzed and compared with the results of the nonlinear model. It shows that the simulation results are in good agreement with the linear analysis results.
