Passionate scientist, professor at ENSMM (Besançon, France) until 2006 and director of the Chronometry, Electronics and Piezoelectricity Laboratory of Besançon between 1978 and 2002, Raymond Besson was renowned in the national and international time-frequency community for his so-called BVA quartz resonators. He died on April 15, 2020.

Two-Way Satellite Time and Frequency Transfer: first use of a Software Defined Radio receiver in UTC calculation

Two-Way Satellite Time and Frequency Transfer, improved by the Software-Defined Radio (SDR) receiver, has been used for Circular T calculation for the first time in March 2020. The comparison between the French and German local realizations of UTC, UTC(OP) and UTC(PTB), was performed using SDR receivers, a method that replaces part of the time-transfer hardware with high-speed digitization and software data processing. This significantly improves the 1-day stability of the time comparison.

REFIMEVE+ General Assembly, 1-2 April 2020 in Grenoble (France) [UPDATE COVID19: event Postponed]

The REFIMEVE+ project (fiber network of frequency reference distribution at ultra-high performance ) will take placeat the LIPhy laboratory (Grenoble) the 1st et 2nd of Avril 2020 [COVID19 : the event is postponed].

This general assembly is opened to  REFIMEVE partners and every people interested in joining the project.

An on-line registration form and a preliminary program will be distributed soon.

Important subjects that will be discussed are : progress of the network, realization and performance of the Paris-Grenoble link, connexion between the Refimeve+ network and Italy, on-going applications.
