| 摘 要： | 我国天文大地网与GPS2000网联合平差是一项大规模的测量数据处理工程,解算的未知数众多,为了便于检查原始观测数据粗差以及验证地面网与空间网的权匹配关系,需要进行单区平差数据处理研究和计算。本文主要讨论单区平差数据处理中的主要模型、大规模稀疏矩阵有效的解算方法并用软件加以实现,用此软件对5000点的实验区数据进行平差计算,得到了有益的结论。

| Abstract: | The Space network and Astro-geodetic network combined adjustment in China is a huge engineering of data processing,and unknown parameters are much more.For checking gross error of raw observation data and testifying weight matching relations of Space network and Astro-geodetic network,the research and calculation of data processing in single area are needed.The paper mainly discusses the math model,the effective solution method of large scale sparse matrix in data processing of combined adjustment,and develops a combined adjustment software.With 5000 points observation data as experimental data,a useful conclusion can be obtained. |
