利用极潮改正模型分析极潮对VLBI台站位移的影响

Using the pole tide correction model to analyze the pole tide influence on station displacement of VLBI

利用极潮改正模型分析了极潮对于地球不同区域VLBI台站位移的影响,以北京所处经纬度为例,利用1992至2010年的极移数据计算出了极潮对于VLBI台站的位移影响值,并分析了其变化特征。

We use the pole tide correction model to analyze the pole tide influence on station displacement of VLBI from different regions of the earth station. Taking the longitude and latitude in Beijing as an example,we use the polar motion data from 1992 to 2010 were calculated for the displacement of pole tide station of VLBI impact value,and analysis of its characteristics.
