利用＂中国地壳运动观测网络＂基准网与全球IGS站的公共站点,采用布尔莎模型求取坐标转换7参数,将地壳观测网络工程基准站点位时间序列与全球解进行绑定。结果显示,转换得到的时间序列N、E向中误差约为2、3mm,与直接融合得到的时间序列的单天误差水平相当,转换得到的站间大地线误差大部分在6mm内,表明该转换方法是可行的。

The paper first introduces in detail the combination method with the Brusa model to integrate several regional time series to derive a unified global time series. Then an example from CMONOC （Crustal Movement Observation Network of China） is taken to test if the combination method is feasible. The precision of the integrated time series with the combination method is below 2mm （North） , 3mm （East） , which is the same as the resuhs from the direct integration of the time series. The precision of the baseline is below 6mm; which proves that the combination method can be used to integrate several regional time series to derive a unified global time series.
