摘　　要：根据双圆锥扫描式红外地球敏感器的工作原理,针对卫星姿态测量与控制过程中存在的俯仰角与滚动角的耦合现象,通过建立卫星姿态耦合误差数学模型,推导出卫星姿态测量计算公式,得到卫星姿态测量与控制耦合误差曲线,为卫星的姿态测量与控制提供数据补偿和精度保证。According to the function theory of double-cone scanning infrared earth sensor, the mathematical model was developed regarding the coupling phenomena of pitch angle and roll angle in the measurement and control of the satellite attitude and the computational mathematical formula of satellite attitude measurement was deduced. The results from above can be used to get coupling errors curve to provide data compensation and assure precision for satellite attitude measurement and control.
