SYRTE

Visites insolites du CNRS: A unique opportunity to visit SYRTE and see quantum technologies in action.

24 August 2023

During the 2023 Science Festival, SYRTE is offering two tours as part of the fourth edition of the CNRS Unusual Tours. A unique opportunity to visit SYRTE and see quantum technologies in action.
Quantum Technologies make it more stable

26 May 2023

A collaboration between SYRTE and the Laboratoire Kastler Brossel has made it possible to produce quantum states with a ’compressed’ noise with a sufficiently long lifetime, almost one second, to be used in compact atomic clocks.
SWOT satellite launching

14 December 2022

The Franco-American Swot (Surface Water and Ocean Topography) mission is launching a satellite into space to reveal the topography of surface waters with greater precision, using a wide-field interferometric radar called KaRIn.
Gaia collaboration awarded : Lancelot M. Berkeley prize 2023

29 November 2022

The Gaia probe provides the most accurate three-dimensional map of our Galaxy. For this, the Gaia scientific consortium, which includes SYRTE researchers and engineers, will receive the 2023 Lancelot M. Berkeley - New York Community Trust Prize for Meritorious Work in Astronomy.
Coherent optical link between the national infrastructures for metrology between France and Italy

7 November 2022

The integration of the fiber optic metrology infrastructures of the two countries, adding through interconnections the research laboratories and observatories of both countries, provides the research community with a physical layer on which new research can be developed and pursued in the long term.  
Mesure magnetism within binary systems emitting gravitational waves

16 September 2022

Will the LISA mission be able to measure magnetism of neutron stars and white dwarfs in binary systems?
Ultra-precise rotation measurement with matter-waves

23 June 2022

The Sagnac effect played an important role in the foundations of the theory of relativity, that led to the development of precision optical interferometers to check the agreement with theory. The Atomic Interferometry and Inertial Sensors team of SYRTE has recently published a precise test of the Sagnac effect using matter waves. The team was able to measure the phase shift induced by the Earth’s rotation and find an agreement with the theoretical prediction at a precision level of 25 parts per million.
At the final stroke

10 June 2022

Soon the last stroke of the speaking clock will happen.
A look back at almost 90 years of history, and how to get the correct time after July the 1st at midnight and one second.
Sébastien Bize winner of the European Frequency and Time Award of the European Frequency and Time Forum

25 April 2022

Sébastien Bize, CNRS research director at the Systèmes de Référence Temps-Espace (SYRTE) laboratory, is the 2022 winner of the European Frequency and Time Award from the European Frequency and Time Forum (EFTF). The award recognises his outstanding contribution to the development of microwave and optical frequency standards for fundamental physics tests and for the realisation of the time unit of the International System of Units.
REFIMEVE listed as National Research Infrastructure

8 March 2022

The Ministry of Higher Education, Research and Innovation has just unveiled the new national roadmap for Research Infrastructures. REFIMEVE is one of the new infrastructures listed in the roadmap.

It is a leader in time and frequenciy metrology and is also specialized in Earth rotation, celestial reference frame and history of Astronomy.
SYRTE has a multidisciplinary research activity with transverse expertise in theory, instrumentation and data analysis and various goals from fundamental physics tests to industrial transfers.It is founder membre of Laboratoire d’Excellence du Programme Investissements d’Avenir FIRST-TF.

It has in charge several international services. Associated with the LNE - Laboratoire National de Métrologie et d’Essais - the SYRTE has the responsability of the national reference time and frequence. With the IERS (International Earth Rotation Service), it deliver Earth rotation parameters and other services.

Its teams take part in training and education by giving university lectures and also spread scientific culture by organizing public talks.
