Conference: De l’astronomie aux horloges atomiques, une fabuleuse épopée de la mesure du temps – May 15th 2025, 6pm – LNE – Paris
Conference on measurements and time
The LNE is continuing its “Les mesures et…” series of conferences, with the fifth “Les mesures et le temps : quel futur ?” conference on May 15, 2025. “.
De l’astronomie aux horloges atomiques, une fabuleuse épopée de la mesure du temps
[conference in French]
Since ancient Egypt, humans have deployed remarkable techniques and strategies to push back the limits of precision in time measurement.
In this lecture, you’ll discover how, in the mid-twentieth century, quantum physics supplanted astronomy to produce time measurements with atomic clocks whose current accuracies reach 18 digits, corresponding to a drift of just one second over 15 billion years. This precision is not ultimate, and will have to be further improved to meet the major challenges of science and society, with a necessary change in the definition of the unit of time, the second, planned for the next decade.

Online Workshop: Sensei Project – March 10th, 2025
SENSEI – Smart European Networks for Sensing the Environment and Internet quality, is a projet funded by the European Union and aimed to develop devices and technologies to turn the global telecommunication fibre network into a pervasive distributed sensor and make the network more resilient and efficient.
On March 10th, SENSEI will be presented to colleagues, stakeholders and potential collaborators in a 2.5 hour-long online workshop. The workshop will start with technical talks from Consortium members, focusing on earlier research achievements feeding into SENSEI, and will then focus on the project overview, followed by an open discussion.
Participation is free upon registration

AG FIRST-TF 2024
The FIRST-TF research federation (Laboratory of Escellence) and the REFIMEVE French Research Infrastucure, are joining together this year for organizing 3 events important for the french Time and Frequency community: their respective General Assemblies, and a workshop on precision synchronization and networks.
These events will be the opportunity for a vast community to network, have scientific exchanges and get the latest informations about FIRST-TF and REFIMEVE.
All the events will take place at Institut Galilée, on the Université Sorbone Paris Nord campus in Villetaneuse.
The dates are the following:
- September 30, 2024, afternoon: lab visits at the Laboratoire de Physique des Lasers,
- October 1, 2024: General Assembly of FIRST-TF
- October 2, 2024: Workshop on “Precision Synchronization and networks”
- 0ctobre 3, 2024: General Assembly of REFIMEVE
Lunches for the 1st, 2nd and 3rd of October are included in the organization. Dinners for the 1st and 2nd of October evening will be organized as joint social events.
Registration is free, but mandatory, for members of structures affiliated to FIRST-TF, REFIMEVE, as well as for invited guests, on this link: https://firsttfrefimeve.sciencesconf.org/
Series of 3 seminars on CSOs at FEMTO-ST (February 1-8-15, 2024)
FEMTO-ST is pleased to organize a series of 3 seminars on February 1, 8 and 15, 2024 from 2:00 pm to 3:30 pm, entitled:
Cryogenic Sapphire Oscillator: 30 years of Research at the FEMTO-ST Institute
by Vincent Giordano, CNRS Research Director at the FEMTO-ST Institute.
This series of lectures can be attended in the Jules Hagg lecture hall at Supmicrotech-ENSMM (Besançon, France) or online at MS TEAMS.
Workshop on Standardization of Galileo Timing Receivers (Prague, February 2, 2024, 10:00-13:00 CET)
The availability of accurate and secure timing information is crucial for a range of strategic sectors. This is especially the case for critical infrastructures, like telecommunication networks, energy distribution grids, financial markets. All of these will benefit from the future Galileo Timing Service.
In a joint effort, EUSPA and the European Commission will host a workshop dedicated present the ongoing standardisation activities for timing receivers, aimed at the publication of the first ever Standard in 2024, a key component of the upcoming Galileo Timing Service. The workshop will provide a great opportunity for discussing with Stakeholders on the benefits for Timing and Synchronisation (T&S) applications, and on the user needs of the Timing community.
The workshop will be hybrid, taking place online and at EUSPA HQ.
