Abstract

A precise two-way satellite time and frequency transfer (TWSTFT) data by using the Dual Pseudo-random noise (DPN) signal was correspondingly compared with the regular TWSTFT and GPS Precise Point Positioning (GPSPPP) between the National Institute of Information and Communications Technology (NICT) and Telecommunication Laboratories (TL) in this study. Our result shows that the frequency stabilities of DPN are competitive with those of the GPSPPP. There was less obvious diurnal in the DPN time transfer data. Since the DPN system has advantages of higher precision and lower bandwidth cost when compared with the regular TWSTFT, it is one of the most potential methods to improve the international time transfer links.
