Abstract
An accurate approach for receiver differential code biases (DCB) estimation is proposed with the BDS data obtained from a regional tracking network. In contrast to the conventional methods for BDS receiver DCB estimation, the proposed method does not require a complicated ionosphere model, as long as one reference station receiver DCB is known. The main idea for this method is that the ionosphere delay is highly dependent on the geometric ranges between the BDS satellite and the receiver normally. Therefore, the non-reference station receivers DCBs in this regional area can be estimated using single difference (SD) with reference stations. The numerical results show that the RMS of these estimated BDS receivers DCBs errors over 30 days are about 0.3 ns. Additionally, after deduction of these estimated receivers DCBs and knowing satellites DCBs, the extractive diurnal VTEC showed a good agreement with the diurnal VTEC gained from the GIM interpolation, indicating the reliability of the estimated receivers DCBs.
