Work Context

The SYRTE, with 125 staff, is one of the world's leading laboratories in the field of metrology, primary time-frequency references and interferometry with cold atoms. The laboratory is located at 61 avenue Denfert-Rochereau, on the Observatoire de Paris website (http://syrte.obspm.fr/)).

The spectacular progress of atomic clocks over the last two decades makes the means of satellite comparisons used until now insufficient in terms of resolution and uncertainty. The transport of frequency and time reference signals by optical fibre is by far the most promising. Time and frequency transfer techniques are established at varying degrees of technological maturity. Several techniques exist on national networks or links. The challenge is the construction of the Europe-wide network and its interconnections with national networks and links.
SYRTE (Observatoire de Paris, CNRS, UPMC, LNE) is in charge of the design and system architecture of this network, as part of a European infrastructure development project, which is financing the position for a period of 2 years.

The engineer will be part of the SYRTE optical frequency team. Under the direction of a research engineer, he or she will work in particular with a design or research engineer dedicated to the project. He or she will work in close collaboration with the French and European partners of the project. The main place of work is the SYRTE, at the Paris Observatory. Missions in Europe are to be planned (2-3 trips of 2-3 days per year).

The project follows the INFRA-INNOV CLONETS project coordinated by Philip Tuckey at SYRTE :
