Abstract: This article describes the research progress of the precise metrology system of the BeiDou/GNSS time and frequency transfer and its application, through the research on the common-view of the BeiDon system, design the GNSS CV precise time service system to compare with the National Time Service Center, in order to achieve the traceability of the standard time UTC. At the same time completes to design the GNSS CV time and frequency metrology service system, which innovatively gives the way to improve the common-view of BeiDon satellite system and develope the multi-mode and multi-frequency GNSS CV transmission equipments.
