控制网平差
adjustment of control network
- 本文研究了利用GPS建立特大桥梁施工控制网中一系列技术问题,对控制网中布设方案、观测时间、平差成果分析、与三角网成果比较等方面进行了较详细的分析。
This paper studied a series of technical issues with establishment of a control network for construction of the very large bridge using GPS and analyzed in detail the layout scheme,observation time,average variance result,comparison with triangle network result,etc. - 文摘:根据控制网改造的特点，推导出在控制网中加测GPS基线向量的优化设计模型；利用加测的基线向量数据与原平差成果进行联合平差，从而修正观测点的精度，利用滤波推估理论推估出未观测点的坐标修正值，从而达到控制网改造的目的。
Abstract: According to the character of reforming existing control network the optimal designing model which adds GPS sides to the existing control network was concluded, the union adjustment was undertook by observed data and old adjusted data to adjust the coordinates of those observed points, then the coordinates of those unobserved points wear adjusted by adjustment of allocation, so that we get to goal of reforming the existing control network.
