Abstract The 40 m caliber radio telescope, at the Haoping station of the National Time Service Center, is crucial to satellite monitoring and maintenance work, but there is limited research on how to accurately measure the phase center reference point coordinates. Aiming at this problem, this article introduces the measurement solution of phase center reference point coordinates, including GPS control net setting, observation and data processing, the measurement of the rotation center’s coordinate and curve fitting, and the coordinate transformation of rotation center to reference point. The results of the precision analysis show that the accuracy of reference points is better than 8 mm in the CGCS2000 coordinate system.
