Intercomparison Study of Time and Frequency Transfer between VLBI and Other Techniques (GPS, ETS8(TCE), TW(DPN) and DMTD)
Hiroshi Takiguchi, Moritaka Kimura, Tetsuro Kondo +15
We carried out the intercomparison experiments between VLBI and other techniques to show the capability of VLBI time and frequency transfer by using the current geodetic VLBI techn…
All-optical link for direct comparison of distant optical clocks
Miho Fujieda, Motohiro Kumagai, Shigeo Nagano +3
We developed an all-optical link system for making remote comparisons of two distant ultra-stable optical clocks. An optical carrier transfer system based on a fiber interferometer…
Direct Comparison of Distant Optical Lattice Clocks at the Uncertainty
Atsushi Yamaguchi, Miho Fujieda, Motohiro Kumagai +7
Fiber-based remote comparison of Sr lattice clocks in 24 km distant laboratories is demonstrated. The instability of the comparison reaches over an averagi…
Remote atomic clock synchronization via satellites and optical fibers
D. Piester, M. Rost, M. Fujieda +2
In the global network of institutions engaged with the realization of International Atomic Time (TAI), atomic clocks and time scales are compared by means of the Global Positioning…
