Abstract：Two-way satellite time and frequency transfer is one of the most precise techniques of time and frequency transfer between laboratories.The NIM01 two-way satellite time and frequency transfer earth station was established in year 2008, and participate the Europe-Asia two-way satellite time and frequency transfer link now. The other participant laboratory is PTB, TL, NICT, NTSC, SU and NPLI. The two-way satellite time and frequency transfer comparative results of NIM and PTB, TL, NICT are analyzed. The results shown that Europe-Asia two-way satellite time and frequency transfer link is stable and the frequency stability (1day) is better than 5×10-15.6 Cesium fountains in 4 Institutes were compared by two-way satellite time and frequency transfer and GPS CP techniques. The calculation results show that the frequency differences of the fountains are not significant.
