| 摘 要： | 针对高速铁路CP0框架控制网数据解算时IGS基准站的选取问题,以沿江城际铁路CP0框架控制网作为研究对象,用试验的方法讨论使用GAMIT软件处理高速铁路CP0框架网时,选择IGS基准站的空间分布和数量分布对基线解算的影响。结果表明,在CP0框架网数据处理时必须选取IGS站提供参考框架,但可不必选择位于南半球的IGS站;选取的IGS站空间分布要均匀,数量上选择4～5个即可。

| Abstract: | Aiming at the problems in the selection of IGS standard stations for high-speed railway CP0 frame control network data processing and taking the CP0 frame control network of Yanjiang Intercity Railway as the research object,this paper discusses the effects of choosing the space and quantity distribution of IGS standard stations on the baseline solution of high-speed railway CP0 frame network.The results show that,for processing CP0 frame network,IGS standard stations must be selected to provide a reference framework when GAMIT software is used to process observational data.But it is not necessary to select the IGS station located in the southern hemisphere,and the selected IGS stations should be evenly distributed,and the number of them should be 4 to 5. |
