摘　　要：模型化处理是飞行器测控工程的重要技术之一。文章以在轨自旋飞行器的姿态运动为研究对象,采用动力学分析的方法,不仅实现了姿态角演化微分方程与转动角速度微分方程的严格解耦,而且提出并建立带关联方程的动态-测量系统模型。基于该系统模型和扩展Kalman滤波/预报算法,建立了姿态角最优估计和转动角速度高精度估计算法。The modeling analysis technique is one of the most important approaches in spaceflight mission. Based on the dynamical analysis, the copling models of the attitudes with angle velocities were successfully decoupled into two series independently differential equations. And, these two series models were integrated into an extended dynamic-measurement system with joint relationship equations. This new integrated model could be widely used in attitude determination, attitude control and attitude monitoring of the spinning spacecraft. Based on this integrated model, a series of practical algorithms were described to estimate attitude as well as spinning angles velocities with high precision.
