Abstract：To establish the optimal strategy for the Beidou precise orbit determination receiver PCC(phase center correction) model, we first compare the IGb R3 and IGb 14 calibration values of GPS, and the small difference between the two sets of model values demonstrates the feasibility of using the IGb R3 instead of the IGb 14 calibration values of the Beidou receiver antennae when they are not provided. Further, we design three sets of receiver PCC models with PCC assignment 0, GPS L1/L2 frequency correction value substitution, and IGb R3 calibration value substitution to analyze their effects on the Beidou precise orbit determination. The results show that the receiver phas center offset（PCO） has a greater influence on the precise orbit determination, and the IGb R3 model has the best result for the Beidou-3 precise orbit, with an average orbit fitting accuracy of 3.4 cm, followed by the L1/L2 substitution value of GPS. It is recommended that using the IGb R3 value for Beidou-3 precise orbit determination before the precise PCC model of the Beidou receiver is published in the latest framework.
