The antenna phase center offset and ranging error caused by its variation can reach several cm or even dm level, which is a key error correction term that must be considered for GNSS high-precision applications. China’s independently self-built Beidou navigation satellite system (BDS) has opened global services, but there is no absolute antenna phase center correction model of Beidou-3 in the field of GNSS that is consistent with the definition of IGS. In this paper, based on a high-precision robot, the absolute phase center field calibration method is studied, and the geodetic-grade e antenna of the monitoring station of the international GNSS Monitoring & Assessment Service (iGMAS) is calibrated for the first time based on the absolute antenna correction platform of Wuhan University. The preliminary results show that the antenna phase model has a frequency binning pattern, and the phase model characteristics with similar frequencies are relatively close. The internal conformity accuracy between the calibration results of multiple time periods is better than 1 mm, and the short baseline positioning verification consistency accuracy can reach 1.5–3 mm.
