Abstract

The remote synchronization of a Very Long Baseline Interferometry (VLBI) station with a “virtual” atomic clock delivered via an optical fiber is described. The time and frequency signals are provided from UTC(AOS) laboratory located at a distance of 345 kilometers from the VLBI station. Evaluation of the remote synchronization carried out by Joint Institute for VLBI ERIC is presented. To our best knowledge, this is the first operational fiber-optic link synchronizing VLBI observations.
