  • Objectives: BDS-3 officially opened its global service on July 31, 2020. To evaluate the BDS-3 global positioning performance in detail. Based on multi-day measured data from 16 MGEX tracking stations around the world. Methods: Net_Diff software was used to carry out the global BDS-3 single-frequency, dual-frequency non-ionospheric combination and dual-frequency non-combination model under dual-frequency, three-frequency non-combination model and three-frequency non-ionospheric pairwise combination model, three-frequency pseudorange single Point positioning solution experiment. And compare with GPS, Galileo some frequencies. Results: The results show that the number of satellites and spatial geometry of BDS-3 in Asia, Europe and Africa are better than GPS and Galileo. For BDS-3 single-frequency pseudo-range single-point positioning, the four frequencies of B1C, B1I, B2a, and B3I have four frequencies of E direction accuracy. It is better than 0.5 m, the accuracy of the N direction is better than 1 m, and the accuracy of the U direction is better than 2 m. Compared with GPS and Galileo, the positioning accuracy relationship is:B1C>B1I>L1>B3I>B2a>E1>L2>E5a. For BDS-3 dual-frequency combined pseudorange single-point positioning, the B2aB3I combined positioning is poor and not suitable for positioning. The B1CB2a, B1CB3I, B1IB2a, B1IB3I combined frequency positioning accuracy in the E and N directions is better than 1m, and the positioning accuracy in the U direction is better 2 m, compared with GPS and Galileo, the positioning accuracy relationship is:B1CB2a> B1CB3I> L1L2> B1IB3I> B1IB2a> E1E5a> B2aB3I. For BDS-3 triple-frequency combined pseudo-range single-point positioning, the positioning accuracy of B1IB2aB3I and B1CB2aB3I in the E and N directions is better than 1 m, and the positioning accuracy in the U direction is better than 2 m. Compared with GPS and Galileo, the positioning accuracy relationship is:B1CB2aB3I> B1IB2aB3I> L1L2L2> E1E5aE5b. B1CB3I, B1IB3I, B1CB2a, B1IB2a dual-frequency combinations are suitable for positioning using non-combined models, B2aB3I is suitable for positioning using non-ionospheric models, and B1IB2aB3I and B1CB2aB3I are suitable for positioning using non-combined models. Conclusions: Combining the experimental results can draw conclusions, BDS-3 has better positioning performance on a global scale. Even some frequency positioning performance is better than GPS and Galileo, which can provide a certain reference for future BDS-3 related research.
