Abstract :
This paper describes how to eliminate the diurnal variations caused by the satellite motion in the Two-Way Satellite Time and Frequency Transfer (TWSTFT) data. Through the analysis of the NICT-TL link, we demonstrate that a precise Sagnac correction is useful to improve the TWSTFT data. The time deviation (TDEV) at an 8-hour averaging time is reduced from 159 ps to 73 ps after the correction.
