摘　　要：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 payload＇s 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 satellite＇s attitude control considering the DEM is shown, which provides a new method to obtain high-precision data.
