GPS Differential Calibration at NTSC

摘要

During August 2002 to November 2002 and July 2004 to November 2004, BIPM (Bureau International des Poids et Mesures) has organized two times GPS round trip calibration in Asia and Pacific region, in order to determine the differential time corrections for GPS time equipments located at the timing laboratories in this area. NTSC (the National Time Service Center of Chinese Academy of Sciences) has undergone the calibrations, the procedures and results of the calibrations are presented in this paper.
