CoRot Mission

In 2014, CNES has stopped CoRot mission after 2137 days of operations (more than twice the design's expected lifetime). CoRot was equipped with a 4-detectors focal plane and a dioptric telescope, both supplied by SODERN.
Mission has been a great success with the discovery of 25 exo-planets. The principle was the detection of tiny light variations of stars, which could be explained by the transit of a planet in front of the star. It requires a very high stability of the detection chain; but also a very stable pointing stability, for which SODERN SED16 star trackers were used.

PHARAO - 2014 IAC Conference

During the 2014 IAC conference in Toronto, Sodern has presented a paper detailing PHARAO's Laser Source and Cesium Tube Flight Models achievement. PHARAO (Projet d'Horloge Atomique à Refroidissement d'Atomes en Orbite) - a scientific project funded by the French Space Agency, CNES - and a Hydrogen Maser, are two atomic clocks onboard ESA's ACES (Atomic Clock Ensemble in Space) platform, which will dock on the International Space Station in 2016. PHARAO will be the first space atomic clock to use the physical principle of atoms cooling, and thus it will be the most accurate and stable clock ever built.

Laser Source and Caesium Tube tested in the PHARAO atomic clock Flight Model

The Laser Source and the Caesium Tube designed and fabricated by Sodern are now integrated and tested in the PHARAO atomic clock Flight Model. The accuracy of the clock is being evaluated by CNES and Syrte. PHARAO is estimated to be in the top 10 clocks on Earth for this parameter. The ultimate performances will be known only in zero gravity after tests on the ACES experiment have begun in 2016.

Flight model of Pharao's Laser Source delivered to CNES

In January, Sodern delivered the flight model of Pharao’s Laser Source to CNES. Pharao is a cold atom clock for fundamental research on the ISS, able to reach the ultimate accuracy of 1 second in 300 millions years.

Sodern has already delivered the Caesium Tube flight model, in which atoms are cooled down to a temperature in the µK range. The caesium atoms operations in the tube need 14 accurately stabilized laser signals, made by the so-called “Laser Source”, a complex double side optical bench.
