【摘要】 介绍了目前处理框架问题的3种参考基准方法:单点基准法、重心基准法、相对稳定点组基准法,并分别用这3种方法对云南境内28个GNSS基准站,近2年观测数据进行试算、验证,并对不同参考基准解算得到的位移场作了比较分析。结果表明,选择位于华南块体的文山GNSS基准站作为云南GPS位移数据处理的参考基准是可行的。更多还原

【Abstract】 We introduced three methods for resolving reference frame problem,such as datum with single point,datum in the centre of gravity,datum relative to stable point.Then,we calculated and compared the displacement field based on the observation data recorded by 28 GNSS Reference Station in Yunnan for two years using these three reference frame methods.The result shows that it is feasible to choose GNSS Reference Station in Wenshan which located in the Southern China block as the reference datum of GPS displacement data processing in Yunnan.更多还原
