分析了静态红外地平仪对卫星姿态测量的影响因素,发现测量误差主要来源于冷云的干扰,为了避开冷云的干扰,减少测量误差,又不使地平仪系统所接收的地球辐射能量太低,需要对光学系统重新进行优化设计。通过重新选择光学波段,并加大光学系统的通光口径,实现了光学系统的优化设计,对优化后系统进行分析计算,相对于优化前,系统所接收到的地球辐射总能量最多降低5%,但冷云的干扰却减少了30%。结果表明光学系统的优化设计将会大大提高静态红外地平仪对卫星姿态的测量精度。
The factors affecting the satellite attitude measurement are analyzed. It is found that the measurement error mainly comes from the cold cloud interference. In order to avoid the cold cloud interference and reduce the measurement error, it does not make the earth radiation energy received by the leveling system too Low, you need to re-optimize the optical system design. By re-selecting the optical band and increasing the aperture of the optical system, the optimal design of the optical system is realized, and the optimized system is analyzed and calculated. Compared with the optimization, the total energy of the earth radiation received by the system is reduced by at most 5% , But cold cloud interference has been reduced by 30%. The results show that the optimized design of the optical system will greatly improve the accuracy of the static attitude measurement of the satellite infrared attitude.
