GAIA : An unrivaled high precision mapping of our Galaxy

21 September 2016

ESA and DPAC release the first results of the space mission GAIA, launched about 1000 days before. The results show the unique measure of the distance to many stars and improve the precision of the one already known from the Hipparcos catalogue by a factor of 3.
Searching for dark matter with atomic clocks

2 September 2016

Atomic clocks at SYRTE provide new limits on scalar dark matter!
Optical fibre link opens a new era of time-frequency metrology

19 August 2016

1400-km of optical fiber link connects the quantum clocks at SYRTE and PTB, and is used to compare them with record uncertainty !
Continuous measurement using cold-atoms gyrometer : a world first !

22 May 2016

The SYRTE’s gyrometer breaks sensitivity record using a joint interrogation scheme.
El-Nino 2015-2016 appears in Earth rotation rate

5 February 2016

During the winter 2015-2016 El-Nino has a visible influence on the length of day, causing an anamoly of 0.5 ms. Such strong El-Nino go back to 1983-1983 or 1997-1998.
Seeing measurement campaign in Saint-Véran

16 January 2016

A seeing measurement campaign is being operated by François Taris at Pic de Châteaurenard (3000 m), close to Saint-Véran. It started october 2014. These measurements aims at characterizing the site. In case of positive results, a robotic telescope will be set up there. The telescope will be dedicated to monitoring of quasars in the optical and follow-up of asteroids in the framework of celestial reference frame tie.
Comparison of atom gravimeters: the CAG of LNE-SYRTE and the Muquans AQG of RESIF

30 November 2015

First comparison between two absolute atom gravimeters at LNE Trappes from the 28^th of september to the the 2^nd of octobre 2015.
First MIGA atomic interferometry module from SYRTE delivered to LP2N

7 September 2015

The MIGA project aims at realizing of a novel infrastructure to study applied and fundamental aspects of gravity using matter wave and optical interferometry techniques in a single instrument. This infrastructure will allow for a deeper understanding of the Earth’s gravity field and serve as a test bench for future low frequency (0.1-10 Hz) terrestrial gravitational wave detectors based on atom interferometry. A milestone of the project was achieved in June 2015 by the successful delivery to (...)
Gaia’s GBOT embarks on asteroid finding programme.

11 May 2015

Making use of data that are generated primary for the tracking of Gaia, the Gaia’s GBOT campaign has now found an additional science application: the detection of asteroids.

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.
