高速铁路CP0框架控制网GAMIT解算结果与IGS站的选取研究
Research on the Relationship between the Results of GAMIT Processing and the Selection of IGS Station in High-speed Railway CP0 Frame Control Network
摘要
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.关键词
