Summary

In this paper we discuss a method for using the Global Positioning System (GPS) to monitor ionospheric irregularities in the high-latitude region. Dual-frequency GPS data, obtained from mid-latitude Australian and sub-Antarctic permanent GPS stations, are used to study various ionospheric features, including large scale travelling ionospheric disturbances (TID’s) and auroral scintillation. These irregularities are characterised by the presence of rapid changes in the Total Electron Content (TEC). A major magnetic storm period in early November 1997 has been selected to analyse the ionospheric irregularities. The storm, which was associated with an X9-class solar flare, was observed by the Australian ionosonde network. The paper presents the early data analysis results and addresses the technique of using GPS to monitor ionospheric irregularities.
