摘要
简要介绍了三线阵测绘卫星的基本工作原理,分析了偏流角产生的原因及其对三线阵相机立体摄影覆盖的影响,提出了采用对卫星进行偏航姿态控制以改正偏流角的策略,给出了对卫星姿态控制系统偏流角改正的控制精度要求,并对偏流角改正的有效性进行了评估。
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.
