Precise information on the ionospheric Total Electron Content (TEC) can be quickly provided by using GPS (Global Positioning System). The theory and methods to monitor the activities of ionosphere by GPS are discussed. It points out that TEC can be used to establish the highly accurate ionosphere model and satisfy the needs of scientific study, and TEC is derived by utilizing the phase observation and solving the differential code bias (DCB) only. The main error sources of TEC estimate are analyzed and the latest progress of ionospheric activities monitored by GPS is described.
