Abstract：Based on the variance components estimation, the receivers DCB and VTEC residual values are calculated by the pseudorange data with carrier phase smoothing and the vertical electronic content (VTEC) and the DCB of satellites. By using 35 IGS stations data, the DCB of 40 IGS receivers are estimated. The results show that the accuracy of DCB can be better than 1 nanosecond compared with the DCB provided by the IGS.
