Time comparisons between KSRI and CRL via the geostationary meteorological satellite of Japan

A time comparison system using the ranging signal of the geostationary meteorological satellite (GMS) of Japan has been developed, and GMS measurements have been carried out between Korea Standards Research Institute (KSRI), Korea and Communications Research Laboratory (CRL), Japan. The result of the time comparison has shown that the precision of the GMS time comparison system at KSRI is about 10 ns. The GMS time-comparison system can be used for T/F transfer in the Asian and surrounding oceanic area with a precision of several tens of nanoseconds.<
