ABSTRACT
With the increase of BDS-3 in-orbit time, the number of the new signal ground stations has been gradually enlarged. So we analysed the time series characteristics of B1C&B2a from various perspectives. The two components of the new signal were solved separately, and the sequence continuity of L1X-L5X was found to be poor. The experimental results showed that the ambiguity resolution and position capability of the new signal individually were inferior to those of the old signal; but theconvergence speed and positioning accuracy of BDS(B1C&B2a)+GPS are improved by 26.8% and 44%, respectively, compared with the old signal of fused.
