Conférence-débat : Le nouveau système international d’unités (SI) fondé sur un choix de constantes physiques fondamentales

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 ».

Call for papers – Workshop on Synchronization and Timing Systems (March 25-28, 2019 – San Jose, CA, USA)

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
  • Transportation/Automotive
  • Cyber-Physical Systems (Industrial Internet, Factory Automation, Computing,
    Sensor Data Fusion)
  • Broadcasting and Multi-Media
  • Other

For sector independent talks choose:

  • Sources of Timing: GNSS, Network Links, Oscillators (Atomic, Qu, MEMS, Other)
  • Timing Security/ Assured Timing
  • Measurement/ System Validation
  • Other

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.

Joint meeting of the ESA Topical Teams: « ACES & General Relativity » and « ACES & Geodesy, clocks and time transfer »

The next joint meeting of the ESA Topical Teams: ACES & General Relativity and ACES & Geodesy, clocks and time transfer will be held at the Technical University of Munich, Germany, between Oct. 22, 2018 and Oct. 24, 2018. This meeting focuses on the utilization of ACES and highly accurate clocks in space, both from a point of view of space geodesy and fundamental physics. Topics of interest are:
1. The application and potential of highly accurate Clocks in Space such as ACES
2. Tests of the Einstein Equivalence Principle (EEP)
3. Laser Time Transfer using Satellites such as ACES and T2L2
4. Future applications of coherent time in space geodesy
5. The distribution of accurate time and frequency for metrology and geodesy

The colloquium will bring together the scientific community interested in the applications of highly accurate space clocks like ACES/PHARAO in all domains, from theoretical physics to cold atoms and application in geodesy and atmospheric studies. Furthermore we look at the scientific potential of near lossless links among high performing ground clocks and satellite clocks, both in time and frequency.

The meeting will consist of invited and contributed presentations on the details of ACES, data analysis and scientific applications. Whilst centered on ACES/PHARAO the colloquium is open to more general contributions on theory and experiments in any of the related subject areas. The aim is to prepare within the broad scientific community for the upcoming launch (2020), the  scientific exploitation of the data and the development of new applications in space geodesy.

The workshop will include both review and contributed talks with ample time for discussion.
