Abstract: rustal Movement Observation Network of China (CMONOC) is the biggest integrated service network in China, and contains 260 GPS stations. In this paper, the basic principle and method of studying ionospheric TEC by GPS is firstly introduced , then the flow of data processing and product release of CMONOC monitoring ionospheric TEC system is detailedly explained. In the end, the coupling relationship between ionospheric anomalies before earthquakes and earthquake occurrence is analysed. And coseismic ionospheric disturbances of the MS7. 0 Lushan earthquake is analysed by using the products of CMONOC monitoring ionospheric TEC system.

Key words: Ionspheric TEC Anomaly Detection, CMONOC, GPS, Coseismic Ionospheric Disturbances
