中国新一代高分辨率三线制立体测绘卫星资源三号（ZY-3）配备了三个传感器（底视、后视和前视）。其目标是完成1：5万地形图的制作和1：2.5万地形图的修测更新。对于推扫式卫星，轨道姿态插值精度直接决定了卫星立体测图精度和无地面控制点的定位精度。本文通过对“资源三号”卫星轨道和姿态的研究和分析，提出了一种新的轨道模型。使用弹道数据集，新的建议弹道的正确性和精度进行了验证，并与其他模型，多项式模型（LPM），分段多项式模型（PPM），和拉格朗日三次多项式模型（LCPM）进行了比较。同时，推导了光束法区域网平差的微分方程。最后，利用ZY-3卫星影像和轨道姿态数据进行几何校正实验，验证了带权多项式分段点模型的正确性和实用性。
The new generation Chinese high-resolution three-line stereo-mapping satellite Ziyuan 3 (ZY-3) is equipped with three sensors (nadir, backward, and forward views). Its objective is to manufacture the 1 : 50000 topographic map and revise and update the 1 : 25000 topographic map. For the push-broom satellite, the interpolation accuracy of orbit and attitude determines directly the satellite's stereo-mapping accuracy and the position accuracy without ground control point. In this study, a new trajectory model is proposed for ZY-3 in this paper, according to researching and analyzing the orbit and attitude of ZY-3. Using the trajectory data set, the correction and accuracy of the new proposed trajectory are validated and compared with the other models, polynomial model (LPM), piecewise polynomial model (PPM), and Lagrange cubic polynomial model (LCPM). Meanwhile, the differential equation is derivate for the bundle block adjustment. Finally, the correction and practicability of piece-point with weight polynomial model for ZY-3 satellite are validated according to the experiment of geometric correction using the ZY-3 image and orbit and attitude data.
