Photogrammetric satellites using commercial grade stellar sensor constitute the attitude determination system,the measurement of attitude existents low-frequency and low-drift systematical error,which can not be ignored and make the stellar sensors units to three-line CCD camera installation angle conversion parameters after the in-flight calibration to generate additional increment dφC,dωC,dκC.In one of the course,these increments can be regarded as constants,relying on its stereo model on the performance of vertical parallax rule.Under the condition without ground control points,adding measures to compensate dφC,dωC and dκC in bundle adjustment,the positioning error of targets improved to 11-22 m.
