Abstract

Abstract: In this paper, the manufacturer's model, MGEX model and ESA model are used to correct the antenna phase center offsets and variations of BDS satellites in precise point positioning. The results show that the three models improve the accuracy of BDS precise point positioning, with an improvement of 1~2 cm and from 1 dm to centimeter level in the horizontal and vertical directions. Meanwhile, the ESA model is better than the other two models. For the receiver phase center offsets and variations, the BDS is corrected by the GPS correction model. Compared with the uncorrected model, the accuracy improvement varies with antenna types, which can be millimeter level in the horizontal direction, whereas it can be centimeter level in the vertical direction.
