中文摘要：
针对全球台站数量剧增、空间定位测量精度越发提高的情况,该文利用ITRF2008框架GPS、卫星激光测距、甚长基线干涉测量实测站速度信息,北美、中国以及欧洲连续运行卫星定位网络站速度信息进行基准统一,联合解算国际地球自转服务协议中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;提出最小二乘海量台站选取方法。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。
英文摘要：
In this paper,datum of velocity was unified with ITRF2008 solutions,North American,CMONOC and European CORS network.The Euler vectors of the main fourteen plate＇s defined by IERS were calculated and refined with the unified velocity.The station selected methods by least square was determined.The results showed that 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.
