摘要
为了弥补遥感卫星偏流角传统计算中假设过多的缺陷,基于卫星工具包(STK)与MATLAB软件,从卫星偏流角修正的物理原理出发,提出了一种仿真与数值计算交互的卫星偏流角修正分析方法。以一颗运行在高650km太阳同步轨道、具有侧摆能力的遥感卫星为例,对其成像点的偏流角和卫星偏流角修正进行了仿真分析。仿真结果表明,文章提出的方法可以精确地分析卫星成像过程中的偏流角,从而可用于对卫星在轨成像性能影响的预估,还能在卫星入轨后用于验证图像质量影响因素的来源,为保障成像质量提供支持。
A simulation-numerical interactive method based on STK and MATLAB is proposed to make up for the analytical limitations in terms of assumptions for remote sensing satellite drift an- gle adjustment. And a 650km sun-synchronous orbit remote sensing satellite with rolling maneu- ver ability is used as an example for the satellite drift adjustment angle analysis. The simulation results show that this method could be used in system design, model verification as well as in- orbit image quality evaluation, and provide basic support for imagery quality assurance.
