摘　　要：针对航天发射初始段测控设备布站受地形影响的问题,提出了一个基于最大仰视角的测控设备选址方法。以测控设备无遮挡最大仰视角的通视性分析方法为基础,在数字高程模型(digital eleration model,DEM)空间数据中,将航天器飞行星下投影点为中心,按照螺旋方式,以中心为起始点由里向外分析布站区域中DEM各网格点与航天器的通视性,通过比较航天器各时刻的通视性,得到某时段内覆盖航天器飞行弧段的可视区域,选择满足两两距离大于规定值的三个网格点作为测控设备选址地点。We introduced a site selection method based on the modified maximum elevation angle intended for mountains possibly affecting the measurement and control of the initial phase in a launching port located in mountainous areas. To use the former analysis results, the method, along the helices whose center is the launcher＇s project point, analyze each point＇s visibility on the helices. The visible area can be obtained by comparing the visibility at each moment in the initial phase. Finally, there can be three points in the above visible area with distances longer than required.
