Abstract 3 D temporalspatial variation regularity of ionospheric electron density were reconstructed by using the ionospheric tomography technique for the GNSS data of 126 stations on 10 June，2005.The diurnal variation regularity of ionospheric electron density distribution and variation characteristics of the ionospheric vertical structure in lowlatitude region were investigated and the prosess of occurrence，development and disappearance of the equatorial anomaly structure were carefully analyzed.The factors that impact the accuracy of ionospheric electron density were discussed，and some suggestions were given for further investigation of ionospheric tomography technique.
Key words ：
