%X A new calculation method of VTEC(Vertical Total Electron Content) of the vertical space above fiducial station is presented, in which the single integer ambiguity and dual frequency observations are directly used to calculate VTEC. The result shows that the change tendency of the calculated VTEC is consistent with the provided data by IGS(International GNSS Service),and its inner precision is so good that can reflect the ionospheric activity in some extent.
