Abstract
The purpose of this paper is to monitor the ionospheric total electron content (TEC) in real time. Firstly, the receiver differential code bias (DCB) and the satellite DCB are calculated by assuming that they are constant value during the whole day. Comparing with the satellite DCB given by the Center for Orbit Determination in Europe (CODE), this paper also analyzes the DCB stability of receiver and satellite. And secondly, according to the stability of DCB, we calibrate vertical TEC (VTEC) by using DCB of the former day, and establish the polynomial model with multi-station in single epoch to monitor the changes of ionosphere. The result of all epoches within a day shows that the average internal RMS of this method can be better than 1 TECU (1016 el/m2), and the average external RMS can be about 1 TECU.
