In ground-based pseudolite positioning system, one of critical problems is to calibrate the antenna phase center (APC) of the pseudolites in the positioning system frame. In this paper, a convenient method is proposed to resolve the problem. At first, the pseudolite antenna acts as a GPS receiver antenna. Therefore, the APC in the antenna frame can be determined in field. In the positioning system frame, the reference point (ARP) and the attitude of antenna can be determined with conventional ground method. Finally, APC can be transformed to the positioning system frame. Positioning results in a calibrated system demonstrate that within a specific indoor experiment an RMS error of less than 1.0 cm was obtained for the horizontal coordinates and 1.1 cm for the vertical one.
