A method of measuring ionospheric irregularity drift velocity by using scintillation signals from multi stations is introduced in this paper. Three Ionospheric Scintillation Monitors (ISM) are installed to test this method in Haikou, China. The result shows that the eastward drift velocity in Haikou near the autumnal equinox ranges from 50 m s to 110 m s. It varies significantly before 22 1 00 LT. In the same scintillation period, when different data lengths are used, the calculated drift velocities show the same tendency. A case study showed that it is feasible to estimate the ionospheric irregularity drift with this method. The temporal resolution of this method can reach 1 mm.
