摘　　要：资源三号卫星是我国首颗高分辨率光学三线阵立体测绘卫星.对于推扫式卫星影像而言,姿态和轨道统计模型的精度会直接影响后期卫星数据处理和无控制点的定位精度.通过对资源三号卫星的姿态和轨道数据进行分析研究,提出逐点带权多项式姿轨模型,推导出该模型在几何处理中的微分方程.使用资源三号卫星数据验证了逐点带权多项式模型对资源三号卫星姿轨拟合的正确性和实用性.ZY-3 is the first Chinese civilian high-resolution stereo mapping satellite. For pushbroom satellite images, the accuracy of statistic model of attitude and orbit decides the accuracy of the processing of satellite＇s data and the positioning without GCP. Based on the analysis for ZY-3＇s attitude and orbit, the Piecepoint with Weight Polynomial Model of attitude and orbit is proposed and the differential equation of the model is de- rived. The correctness and practicality of the Piecepoint with Weight Polynomial Model for interpolation of attitude and orbit was verified by the data of ZY-3.
