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.
UFFC-JS 2024 (Taipei, September 22-26, 2024)
The 2024 IEEE Ultrasonics, Ferroelectrics, and Frequency Control Joint Symposium will take place September 22 – 26, 2024 at the Taipei Nangang Exhibition Center in Taipei, Taiwan. This joint conference celebrates the 70th anniversary of the IEEE UFFC Society.
The following conferences will be involved:
- International Ultrasonics Symposium (IUS)
- International Symposium on Applications of Ferroelectrics (ISAF)
- International Frequency Control Symposium (IFCS)
- Piezoresponse Force Microscopy Workshop (PFM)
EFTF 2024 (Neuchâtel, June 25-27, 2024)
The European Frequency and Time Forum (EFTF) is the Europe’s leading technical conference for time and frequency products and related technologies. The congress brings together researchers and technologists from manufacturers, service providers, operators, application developers, National Metrology laboratories, defense timing, and standards bodies to share the latest information and promote the development of precise time and frequency systems and components.
The conference will comprise invited plenary presentations as well as parallel oral and poster presentations. Last held in Neuchâtel in 2014, the 2024 edition of the conference will once again be held at the University of Neuchâtel, in the beautiful lakeside city of Neuchâtel, Switzerland. The main conference venue is the Aula de Jeunes Rives. This will mark the 37th edition of EFTF.
WRC-23 approves the adoption and implementation of Continuous Universal Time Coordinated UTC
The ITU World Radiocommunication Conference 2023 (WRC-23), held in Dubai, United Arab Emirates, from November 20 to December 15, 2023, approved the adoption and implementation of UTC Continuous Universal Time as the internationally recommended reference time scale. Successful negotiations focused on the importance of making UTC a continuous time scale, and on the revision of Resolution 655 (WRC-15) concerning the definition of a time scale and the broadcasting of time signals using radiocommunication systems. The main results include :
- Recognition of Resolution 2 of the 26th CGPM (2018) on the definition of UTC and Resolution 4 of the 27th CGPM (2022) on the use and future evolution of UTC. The latter aims to provide a continuous reference time scale for a century;
- Recognition of the results of studies carried out by Working Party 7A and published in Report ITU-R TF.2511, dealing with the various aspects of the current reference time scale and those that could be defined in the future, including their implications and applications;
- The continuation of the fruitful collaboration between the BIPM and the ITU-R, in preparation for the decision of the 28th meeting of the CGPM (2026) concerning the new maximum tolerance for UT1 – UTC and its date of application;
- The continuation the study of the content and structure of time signals to be broadcast using radiocommunication systems, including wireline technologies, using the combined technical expertise of the organizations concerned, in order to produce new and revised ITU-R reports and recommendations, including but not limited to a revised version of Recommendation ITU-R TF.460-6 on standard frequency and time signal emissions.
