基于复杂地形高分辨率卫星编程规划方法研究与仿真

针对当前航天遥感平台普遍采用的统一高程规划地表,对工作在凝视扫描模式下的高分辨率卫星会产生的诸如目标漏扫、目标重复扫描等问题进行了分析,提出在有效载荷参数范围内,结合低精度DEM来控制卫星姿态变化的方法,并且基于NASA的World Wind三维地球数据浏览软件进行了二次开发,直观地模拟了基于DEM进行姿态控制的卫星在轨运行状况,为获得高精度数据提供了一种新思路。

The surface of the earth is considered as a unified elevation when satellite remote sensing platforms imaging,but these problems such as target missing and target detection repeatition will be caused significantly with high-resolution sensor in staring mode.Based on the analysis to these problems,a new method to control the satellite attitude combining with low accuracy DEM within payloads ability is put forward in this paper.Futhermore based on World Wind a three-dimensional Earth data browsing software developed by NASA,the Effect Drawing of satellites attitude control considering the DEM is shown,which provides a new method to obtain high-precision data.
