In this paper we report the evaluation of an optical lattice clock based on neutral mercury with a relative uncertainty of $1.7\times {10}^{-16}$ . Comparing this characterized frequency standard to a ^133 Cs atomic fountain we determine the absolute

In modern navigation systems the distance measurements are based on the time spent by the information along the path between the emitter and the receiver. In all GNSS the user only receives signals broadcast from satellites, and the synchronization b

We use six years of accurate hyperfine frequency comparison data of the dual rubidium and caesium cold atom fountain FO2 at LNE-SYRTE to search for a massive scalar dark matter candidate. Such a scalar field can induce harmonic variations of the fine

We performed a carrier-phase two-way satellite frequency transfer (TWCP) experiment between LNE-SYRTE and PTB for several days in September 2015. Different hardware configurations were analyzed at the LNE-SYRTE earth station and a suitable configurat

We report the operation of a dual Rb/Cs atomic fountain clock. (133)Cs and (87)Rb atoms are cooled, launched, and detected simultaneously in LNE-SYRTE's FO2 double fountain. The dual clock operation occurs with no degradation of either the stability

CNES, LKB and SYRTE are developing a primary frequency standard, called PHARAO, which is specially designed for space applications. The clock signal is referenced on the frequency measurement of the hyperfine transition performed on a cloud of cold c
