顾及系统参数的GNSS基线网平差及软件设计

针对使用GNSS技术获取高精度的CGCS2000坐标网平差理论与程序优化设计问题,笔者详细地阐述了基于GAMIT/GLOBK软件的独立基线提取、随机模型生成、系统参数与误差模型、基线粗差处理、程序运行效率等功能开发了网平差软件,采用我国东北部某区域连续运行基准站数据与GLOBK结果比对分析,结果表明:软件模型准确、平差结果可靠、计算效率快,可满足高精度网平差要求。

GNSS Baseline Net Adjustment and Software Design by Considering Systematic Parameters

In connection with the theory and programming of obtaining the high precision of CGCS2000 coordinate,we detailed introduce the independent baseline covariance extract based on GAMIT/GLOBK,stochastic model,systematic parameters,errors model,gross error process and program efficiency.Develop the GNSS baseline net adjustment software,take the region's CORS data of northeast China to analysis with the GLOBK adjustment result,the results indicate that,the software model is accurate,the result is reliable,the computation efficiency is fast,the software can meet the requirement of high precision net adjustment.
