Abstract Static data were conversed as dynamic modal using dynamic Precise Point Positioning（PPP）technique.Comparison of the Zenith Tropospheric Delay（ZTD）of the dynamic PPP to the ZTD of static PPP indicates that the dynamic PPP technique by using higher sampling interval SCBs（30s or higher）can also obtain highprecision ZTDs.This study provides a new method to achieve water vapor acquisition.
