摘要
首先从ITRF2020框架中筛选能接收北斗信号的站点;然后从数据完整性、卫星可见性、多路径误差等方面对站点观测数据质量进行分析,设定相应标准进行筛选;最后基于格网法提出一种既考虑均匀性又考虑数据质量和站点稳定性的选站方法。利用该方法优选72个全球均匀分布的测站作为北斗坐标框架解算中的IGS参考站。
Firstly,from ITRF2020 we screen the stations that can receive Beidou signal.Then,we analyze the site observation data from aspects such as data integrity,satellite visibility and multipath error,and the corresponding criteria are set for screening.Finally,based on grid method,we propose a station selection method considering both uniformity and data quality as well as station stability,by which we select 72 stations evenly distributed around the globe as IGS stations in Beidou coordinate frame solution.
