| 摘 要： | 在介绍各种GPS静态方法和动态定位方法的基础上，对我国武汉及昆明IGS站点在汶川地震时的时变特征进行了分析，通过数据处理可以发现，IGS跟踪站点在地震前后的动态结果无论是采用双差结果还是精密单点定位结果，都显示其有明显的变化，而采用动态定位更能显示这种变化。同时，IGS跟踪站点长期变化还无法反映地震的前兆影响。

| Abstract: | The time-variations of Wuhan and Kunming IGS stations during the Wenchuan earthquake are analyzed with various strategies of GPS static and kinematic positioning.It shows that the dynamic solutions are of obvious change in the earthquake,either by double-difference model or by precision point positioning model,and kinematic positioning method gives better results.The long-term changes of IGS sites,however,can not reflect premonitory impact of the earthquake. |
