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。
According to the design requirements of 65-meter radio telescope project of Shanghai Observatory, Chinese Academy of Sciences, this paper tests and analyzes whether the center of the anchor bolt of the radio telescope orbital foundation and the center circle of the anchor bolt of the tower foundation are correctly tested. Data acquisition, theoretical knowledge, data processing and other related issues. Finally, the measurement theory is adopted to remove the gross errors of the collected data and carry out the corresponding processing and analysis. The conclusions are as follows: The data acquisition and implementation scheme is feasible; the residual pitch of the circular orbital center circle and the center circle of the base meet the actual specification Requirements, orbital center circle inside and outside the ring concentric, orbital base center circle and the center of the tower base concentric.
