摘要: 主要讨论了国土星卫片的成象比例尺,卫星姿态误差对图象几何精度的影响及其姿态参数的控制精度等问题。在简化模型的前提下,按照严谨的数学关系,本文导出了卫片的比例尺和误差计算的数学解析式,并提出了在给定最大定位误差时,对卫星姿态控制精度的总体设计要求。

Abstract: This paper discusses the scales of the satellite panoramic images, the geometric distortions caused of the image by the error of the satellite attitude parameters,and the control accuracy of these parameters.Based on the mathematical methods,it deduces the mathematical formulae of the scales and the error calculation by means of the simplified model.For a given maximum positioning error,it also gives requirements of system design for the accuracy of the attitude control.
