The implementation of Global Navigation Satellite Systems (GNSS) increases the performance requirements in smaller clocks. In addition to past works in the field of optically pumped caesium beam compact clocks (Cs4), SYRTE designs and develops two kinds of clocks within the previous frame:
CPT, for Coherent Population Trapping. The pulsed CPT interrogation technique (SYRTE) is patented. This innovating method gives a high performance even with thermal atoms. It is currently implemented at (...)
