摘要: 由Hamilton原理建立了带有大型拓性太阳帆板的卫星的数学模型;还建立了卫星姿态运动、轨道运动、地球自转、地球曲率、高斯投影等影响下的星载线阵CCD成像模型。利用以上模型和数字计算机仿真技术,仿真分析了太阳帆板的弹性振动和卫星姿态的相互影响对图像质量的影响。

Abstract: In this paper,the dynamical model of a satellite with a large flexible solar array is presented by using Hamilton principles.The satellite CCD photograph model under the effects of orbit motion, earth rotation,earth shape and the Gauss map, etc. is also presented.These models are used to analyse and estimate the influence of the array elasticity vibration on the CCD image geometry quality.
