The Portable Cesium Clock Time Transfer at the Nano Second Level

Shinn-Yan Lin and Wen-Hung Tseng

Abstract:	We introduced the Closure Portable Clock time/frequency Transfer (CPCT) to be a complementary way of GNSS common view (GPSCV) for time transfer/calibration at a remote site especially in urban canyon environment. Three CPCT trips with a cesium clock over a 25 km baseline were conducted to approve the efficiency and precision of the method. In the case the round trip was completed within 3 hours, the calibration results of three CPCT trips show less than 0.14 ns inconsistency and about 0.5 ns standard deviation with respect to the corresponding GPSCV results.
