Abstract：Firstly,the methods and models for correcting antenna phase center offsets(PCO) and phase center variations(PCV) in highaccuracy GPS positioning are introduced,then using precise point positioning procedures the measured data of IGS stations are calculated and analyzed.The results show that in horizontal direction, PCO and PCV less influence on precise point positioning precision,while in elevation direction, PCV brings about cm level effect and the effect of PCO is in 5 mm.Compared with the relative antenna phase correction model,the absolute phase correction model has more advantages, especially in high precision GPS clocking.
