摘要
将ITRF2008解算结果 GPS、SLR、VLBI实测站速度信息和北美CORS网络、中国陆态网络、欧洲CORS网络站速度信息进行基准统一,联合解算IERS组织划定的全球14个主要大陆板块的欧拉矢量,对原有的板块运动参数进行精化;提出了基于最小二乘法的海量台站选择方法,实验结果表明,该台站选取方法能够有效提高海量台站的筛选效率和可靠性。稳定台站的数量越多,分布越均匀,越能够体现板块运动的现势性。
Datum of velocity was unified with ITRF2008 solutions,North American CORS network,CMONOC and European CORS network. The Euler vectors of the main fourteen plate＇s definite by IERS were calculated and refined with the unified velocity. The station selected methods by least square was determined. According with the experiment we can found that the LS method was good at improving the efficiency and security of selecting stations. The status of plate motion could be incarnated greatly with more steady stations and equably distributing.
