Short summary

The differential code bias (DCB) is one of main errors for high-precision GNSS TEC estimation and positioning applications. In this paper, daily DCBs of the BeiDou System (BDS) are estimated and investigated from multi-GNSS network observations (2013–2014), which are compared with GPS results. The DCB of BDS satellites is a little less stable than GPS results, especially for GEO satellites. Zero-mean condition effects are not the dominant factor for the higher RMS of BDS satellite DCB.
