Research activities:

The group metrology at microwave frequencies at SYRTE, Observatoire de Paris, is developing cesium and rubidium atomic clocks following three main orientations:

  • cold atom fountain clocks contributing to the definition of the second of the international system of units and to the generation of national and international time references;
  • compact atomic clocks, for industrial and space applications;
  • participation to the ACES/PHARAO space mission, including the cold atom clock PHARAO.
