Abstract This paper analyzes the influence of antenna phase center offset models and the combination of new and legacy frequencies on the BDS-3 precise orbit determination and positioning. The results show that generally the orbit determination and positioning based on the CSNO PCO model are slightly better than the IGS protocol model.Compared to the effects caused by the differences between CSNO and IGS PCO models, the selection of combination frequencies of B1C/B2a and b1I/b3I has a more significant impact on precise point positioning. In addition, taking the IGS B1I/B3I PCO model as a reference, the accuracy of positioning coordinates in E, N and U component using the CSNO B1C/B2a PCO model are improved by 5%, 13% and 14% respectively, so it is recommended to be used in BDS high-precision data processing.
