dc.description.abstract | The synchronization between atomic clocks plays an important part in both radio astronomical and geodetic Very Long Baseline Interferometry, as the clocks are responsible for providing time and frequency reference at radio stations. The availability of highly stable optical fiber links from a few radio observatories and their national metrological institutes has recently allowed the streaming of frequencies from optical clocks based on the Sr/Yb lattice technology (even two order of magnitudes more stable than H-maser clocks). We will present the current status of the Italian Link for Frequency and Time (LIFT) and the ongoing e orts to realize a geodetic experiment utilizing the radio stations in Medicina and Matera connected in common clock via the optical fiber link. We will then show the results from the latest VLBI clock timing experiments also making use of the LIFT link to compare atomic clocks of the three italian radio VLBI antennas (Mc, Sr and Nt) using the rms noise in the interferometric phase. VLBI clock timing proves more e ective than Global Navigation Satellite System and less expensive than Two-Way Satellite Frequency and Time Transfer in synchronizing remote clocks. | en_US |
