Abstract
The initial performance of the BeiDou single-epoch dual-frequency RTK is evaluated. The success rate and reliability of single-epoch dual-frequency ambiguity resolution (AR) by BeiDou or BeiDou/GPS are analyzed, which are also compared with those by GPS alone. The results show that the BeiDou-only dual-frequency RTK is already feasible, whose single-epoch AR performance and positioning accuracy are compared to those of GPS alone. Furthermore, the success rate and reliability of BeiDou/GPS single-epoch AR are improved when compared to GPS, in particular under high cut-off elevation situations. It is also observed that the improvement of positioning accuracy reach to 31 % for the very short baseline of 4.2 m and is 2.9 % for the short baseline of 8.2 km.
