Abstract :
This paper focuses on the influence of attitude stability and pointing accuracy on satellite-based TID camera. The influence of pointing accuracy and attitude stability on image motion velocity and drift angle is calculated by establishing the simplified model of earth, satellite and camera. MTF (modulation transfer function) and Vector coordinate transformation is applied in this paper. The final result is for the TDICCD which is 96 stages, the yaw axis pointing bias need to be 0.12°,the roll axis and pitch axis stability need to be 0.0017°/s, so that the integration bias will be less than 0.2 image cell.
