| Abstract: | In this paper, the principle of the three-line array mapping satellite is briefly introduced. Through analyzing the cause of drift angle and the influence of drift angle on satellite photography of three-line array camera, the tactic of correction for the drift angle, by attitude controlling of satellite in yawing, is proposed. At the same time, the specification of controlling accuracy on the attitude control system of satellite for the drift angle correction is put forward. At last, the validity of drift angle correction of the three-line array mapping satellite is evaluated. |
