高速铁路CP0数据处理中基线解类型分析
|
摘要
本文为分析GAMIT软件中LC_AUTCLN、LC_HELP、L1_ONLY、L2_ONLY、L1,L2_INDEPENDENT和L1&L2这6种基线解类型在高速铁路CP0的基线解算效果,确定哪些基线解类型可用于高速铁路CP0的基线解算,通过在GAMIT10.60软件中设置不同的基线解类型对苏南沿江城际铁路CP0的外业观测数据进行基线解算,采用同济大学TGPPS软件对解算基线进行网平差,以均方根误差、基线重复性、网平差等对解算结果进行对比分析。结果表明,L1_ONLY、L2_ONLY、L1,L2_INDEPENDENT和L1&L2不满足高速铁路CP0高精度基线解算,LC_AUTCLN和LC_HELP解算精度基本相当,均可满足高速铁路CP0高精度基线解算的要求。
LC_AUTCLN,LC_HELP,L1_ONLY,L2_ONLY,L1,L2_INDEPENDENT and L1&L2 are the six types of baseline solutions based on GNSS dual-frequency observations in GAMIT software.In order to analyze the solution effect of these six types of baseline solution types on the high-speed railway CP0,this paper applies these six types of baseline solution to the CP0 of the south of JiangsuYanjiang intercity railway.The adjustment of baseline network is made by TGPPS software from Tongji University.The results are compared with the results of root mean square error,baseline repeatability and network adjustment.The results show that L1_ONLY,L2_ONLY,L1,L2_INDEPENDENT and L1&L2 are not suitable for high-speed railway CP0 high-precision baseline calculation.LC_AUTCLN and LC_HELP can meet the requirements of high speed rail CP0 high-precision baseline calculation.
