  1. The result shows that the solar radiation pressure moments play a mainly part. based on kalman filtering, three kinds of attitude determination algorithms were studied using the attitude sensor now available on the explorer : the first based on digital solar sensor ( dss ) and gyroscope when the star sensor is not available ; another based on dss, high - gain antenna ( hga ) and gyroscope when the explorer is in the earth - safe mode ; the third based on star sensor combined with gyroscope when the explorer is in the normal mode

    針對配置了典型測量敏感器的深空探測器,基於擴展kalman濾波給出了其姿態確定的方法:針對星敏感器不可用情形,給出了使用太陽敏感器和速率陀螺定姿的濾波器演算法;針對安全模式下的對地穩定定向情形,給出了太陽敏感器和高增益天線融合速率陀螺信息的定姿演算法;針對正常巡航模式給出星敏感器和速率陀螺聯合定姿演算法。
