摘　　要：在分析资源三号卫星成像特性和物理结构的基础上,提出了基于拼接CCD的分段多项式系统误差模型,同时对资源三号卫星的姿轨数据进行分析研究,提出逐点带权多项式姿轨模型。采用资源三号卫星的高精度模拟数据进行在轨几何标定实验,验证了拼接CCD的分段多项式和逐点带权多项式更加适合于资源三号卫星的在轨几何定标。ZY-3is the first Chinese civilian high-resolution stereo mapping satellite.For ensuring the accuracy of mapping and positioning,the paramters of scanner must be carried outthe on-orbit calibration.In this paper,the piecewise polynomial error model are proposedduring the analysis of ZY-3satellite＇s imaging properties and physical structure.The piecepoint with weight polynomial model of attitude and orbit is proposed basing on the analysisfor ZY-3＇s attitude and orbit.The geometric calibration experiments were carried out withthe high-precision analogue data of ZY-3,and the result of experiement verified the piecewisepolynomial model and the piecepoint with weight polynomial model are more suitable for theon-orbit calibration of ZY-3.
