多波束天线结构精密工程测量应用研究

Application Reserch on the Precise Engineering Survey of Multiple Beam Torus Antenna Structure

针对新型多被束天线（MultipleBeamAntenna-MBA）结构系统定位、安装、调整、检测等各阶段的测控要求，结合精密工程测量的多种手段，论述了一套应用GPS进行地面站站址定位与定向的方案，建立天线测技基准即地面安装测量控制网，非接触的空间前方交会测算观测点三维坐标，应用近景摄影测量进行反射面精度检测。

According to the surveys control task of the new multiple beam torus antenna(MBTA) structure on system location, assembly, adjustment, and examination stages, thispaper puts forward a rough plan to meet those deman by using various precise engineeringsurveying techniques: applying GPS to position and orientation of the earth terminal station;estabishing the antenna surveying control foundation-the assembly surveying control netword;measuring and computing the three dimensional coordinate of the observation points by spatialfront intersection; and using photogrammetry for examining the the reflector surface deviations.Compared with the traditional touch methods, this new surveying plan is more flexible andefficient, and it can be extended to the application of the other engineering and industrialsurveying.
