Abstract:A method to improve BDS positioning using GPS antenna phase center correction is introduced, as there is no authority agency provide the information of BDS receiver antenna phase center so far, limiting high precision positioning. They are deduced and argued from two aspects: precise point positioning (PPP) and relative positioning. By using these processing methods, the up component of BDS PPP is improved from 1dm level to several cm, and the up component of relative positioning is improved from cm level to several mm. The results indicate it is reasonable to use these methods.
