Abstract Receiver antenna phase center variation is one of important error sources influencing the precision orbit determination of low earth orbit satellites. In this paper, based on the GPS data of ZY3-01 star, the PCV models are estimated using the reduced-dynamic method and the residual method, and the influence of PCV on the precision orbit determination is analyzed. After using the PCV model, 3D accuracy in overlapping arcs comparison can increase 4.5mm, and SLR residual can increase 1.2 mm. All SLR station checking results also increase.
