【摘要】：根据中国科学院上海市天文台65米射电天文望远镜项目设计要求,本文对射电望远镜轨道基础地脚螺栓中心圆与塔基地脚螺栓中心圆是否准确定位进行检验与分析,并对拟合过程中涉及到的数据采集、理论知识、数据处理等相关问题进行研究。最后运用测量理论对采集的数据进行粗差剔除并进行相应的处理和分析,得出如下结论,数据采集实施的方案可行,轨道基础中心圆与塔基中心圆的点圆距残差满足实际规范要求,轨道基础中心圆的内外圈同心,轨道基础中心圆与塔基中心圆同心。
[Abstract]:According to the design requirements of the 65-meter radio telescope project of Shanghai Observatory of the Chinese Academy of Sciences. This paper examines and analyzes whether the center circle of the ground bolt of the radio telescope track foundation and the center circle of the foundation bolt of the tower are located accurately, and the data acquisition and theoretical knowledge involved in the fitting process are also given. Data processing and other related issues are studied. Finally, the gross error of the collected data is eliminated and the corresponding processing and analysis are carried out by using the measurement theory. The conclusion is as follows: the scheme of data acquisition is feasible. The distance between the center circle of the orbit foundation and the center circle of the tower foundation meets the requirements of the actual specification. The inner and outer circles of the center circle of the orbit foundation are concentric, and the center circle of the orbit foundation is concentric with the center circle of the tower foundation.
