Data pubblicazione: | 2017 | Rivista: | SCIENTIFIC REPORTS | Numero: | 7 | Fascicolo: | 1 | Da pagina:: | 40992 | Abstract: | We describe a VLBI experiment in which, for the first time, the clock reference is delivered from a National Metrology Institute to a radio telescope using a coherent fibre link 550 km long. The experiment consisted of a 24-hours long geodetic campaign, performed by a network of European telescopes; in one of those (Medicina, Italy) the local clock was alternated with a signal generated from an optical comb slaved to a fibre-disseminated optical signal. The quality of the results obtained with this facility and with the local clock is similar: interferometric fringes were detected throughout the whole 24-hours period and it was possible to obtain a solution whose residuals are comparable to those obtained with the local clock. These results encourage further investigation of the ultimate VLBI performances achievable using fibre dissemination at the highest precision of state-of-the-art atomic clocks. | URI: | http://hdl.handle.net/20.500.12386/26988 | URL: | https://www.nature.com/articles/srep40992 | ISSN: | 2045-2322 | DOI: | 10.1038/srep40992 | Bibcode ADS: | 2017NatSR...740992C | Fulltext: | open |
