The EFTS is an intensive full-week seminar intended to provide education and training with lectures and laboratory sessions. It targets a broad audience: Engineers, Ph.D. Students, Post-doc Fellows, Young Scientists, Newcomers, etc.
This seminar is original in the following:
· Broad spectrum of topics related to time and frequency
· Broad target audience, yet keeping high level education
· Balance between academic and applied issues
· True laboratory sessions (as opposite to demos). The attendees are expected to practice on a wide range of instruments made available.
At the 2019 EFTS, we plan 23 lectures, 12 H labs in small groups, visits at the Femto-ST Institute and the Observatory of Besancon, social events, and an Astronomy Session on the “exact time” from stars.
Registrations will only open at the end of January. However, pre-registrations (no invoice issued) are welcome.
Detailed program and Abstracts are being prepared, and will be available later. In the meanwhile, you can download the Abstracts of the previous edition.

January 2019: Registrations open.
Thursday, April 25, 2019: Early Birds (reduced rate) deadline.
Wednesday, June 12, 2019: Regular Participants (full rate) deadline.
Notice that there is a limited number of places set by the capacity of labs, first registered, first served.
A small number in excess can be allowed on a reduced version of the seminar (full lectures, and 4-6 H labs only). Contact us for availability and rate.
The EFTS is a non-profit seminar started in 2013 by Enrico Rubiola, and run every year at the Femto-ST Institute. It is sponsored by Gov, Academic and Int’l Institutions, and lives on the volunteer work of its Instructors and Staff.
The Femto-ST Institute is a French Gov lab affiliated to the National Research Council CNRS under the number UMR 6174.

Abstract: This thesis is part of the research and development of surface elastic wave components for the harsh environments exceeding 600°C. The objective is the realization of surface elastic waves self-encapsulated components which can reach a temperature of 900 ° C. In this work, we introduce a modulization method allowing a finite element finite resolution of an inhomogeneous bias. This method allows to directly calculate the bias problem and to extract the parameters calculated with the perturbation method as well as other parameters. This method contributes to the improvement of the realism of numerical simulations of structures subjected to wide variations of environmental parameters. We describe in this manuscript the approach of the study, the design, the realization and the tests of unencapsulated surface wave resonators for air annealing cycles up to 900 ° C as well as a bench of measurements allowing to perform the measurements in situ. We also discuss the design and implementation of the encapsulation of these resonators by an innovative technology by Wafer-Level Packaging for high temperatures.
The 26th General Conference on Weights and Measures (CGPM) will take place in Versailles in November 2018. At this meeting, we expect the CGPM to approve a resolution to revise the definitions of the International System of Units, the SI, which is based on the second, the metre, the kilogram, the ampere, the kelvin, the mole and the candela (the SI base units).
Over the last 50 years, scientists have measured constants of nature, such as the speed of light and the Planck constant, with increasing accuracy; indeed the metre was already redefined back in 1983 in terms of the speed of light. The inherent stability of these constants make them ideal for underpinning new definitions of the SI units and preparing the measurement system to meet the future demands of science and technology.
If the resolution is approved, the SI will be based on seven physical constants, and thus inherently stable. Most notably, this will mark the end of the last remaining physical artefact in the SI system – a cylinder of metal known as the International Prototype of the Kilogram.
The work needed to reach this point has taken many years, and has been a truly international effort. The universality of access that it will afford has been a long-standing goal for the metric system, dating back more than 200 years.
La 5ème Assemblée Générale de REFIMEVE+ se tiendra les 20 et 21 novembre 2018 dans les locaux de FEMTO-ST de l’ENSMM à Besançon. C’est l’un des partenaires de REFIMEVE+, déjà raccordé au signal métrologique.
Comme les années précédentes, cet événement s’adresse en priorité aux partenaires académiques et industriels du projet mais aussi à tous les acteurs qui s’intéressent au temps fréquence, à la métrologie et à toutes leurs applications liées.
Quelques sujets importants qui seront abordés :
- La première réalisation d’un lien fibré métrologique utilisant des équipements industriels ;
- Avancées du projet de supervision à distance du réseau REFIMEVE+ ;
- Avancées du déploiement des équipements REFIMEVE+ sur le réseau RENATER ;
- Prolongation du consortium REFIMEVE+ au-delà de 2019.
Une séance de posters est prévue.
L’émergence d’une métrologie quantique a permis de rattacher toutes les unités de base à des constantes fondamentales de la physique. Un nouveau système d’unités a donc été proposé à la Conférence Générale des Poids et Mesures de novembre 2018 qui supprime en particulier le kilogramme étalon matériel des unités de base. Cette évolution permet de garantir une universalité, une pérennité et une meilleure reproductibilité des mesures. Le choix des constantes va assurer une cohérence au nouveau système fondé essentiellement sur les progrès de l’interférométrie atomique et de la métrologie électrique quantique. Les développements de ces disciplines et leurs applications en métrologie seront discutés au cours de cette séance.
Conférence-débat de l’Académie des sciences, le 4 décembre 2018 de 14h30 à 16h45, dans la Grande salle des séances de l’Institut de France : “Le nouveau système international d’unités (SI) fondé sur un choix de constantes physiques fondamentales”.

The Workshop on Synchronization and Timing Systems (WSTS) is approaching 30 years of bringing together leading experts to discuss the latest timing and synchronization topics. Over this period, time synchronization has evolved from a niche application to an underpinning technology across Power, Telecommunication, Finance and many other industries and applications.
WSTS has tracked and helped the evolution of precision timing over these decades. This has allowed experts to meet and offers the opportunity to explore cross-industry innovation, as an array of timing technologies become increasingly essential to many sectors.
We particularly welcome presentations offered by the users of synchronization, especially new innovations/applications which provide an important perspective on the needs for timing and on related challenges.
For submitting a Presentation abstract, you will find that we seek either those that are relevant to a specific sector or technology area, and those that are sector independent.
Sector-related talks must choose:
- Telecom (e.g., 5G)
- Electric Grid/Power Industry
- Financial Services
- Cyber-Physical Systems (Industrial Internet, Factory Automation, Computing,
Sensor Data Fusion)
- Broadcasting and Multi-Media
For sector independent talks choose:
- Sources of Timing: GNSS, Network Links, Oscillators (Atomic, Qu, MEMS, Other)
- Timing Security/ Assured Timing
- Measurement/ System Validation
Presenting at this event positions your ideas in front of the top professionals in the timing and sync community. Please submit an abstract no later than Friday, October 5, 2018, to have your concepts considered.

- Software Defined Radio, radio prototyping,
- RF design,
- RADAR design
- Signal processing in embedded systems,
- GNU Radio development environment,
- New platforms
GNU Radio users and developers are invited to present their experiments and activities. The first day (17th of June) will be devoted to oral presentations, posters and demonstrations. The second day (18th of June) will be dedicated to tutorials and hands-on sessions.
Contributions might for instance address the following topics (but not limited to):
- Cognitive Radio, Digital Communication and Agile Spectrum Sharing
