A chip-scale atomic clock. HU DONGDONG/FOR CHINA DAILY China has taken a significant step in high-precision timekeeping by mass-producing a fingernail-sized chip-scale atomic clock that is accurate to ...
Abstract: This paper proposes Kalman filter algorithms for unobservable systems. The proposed algorithms are effective in the time scale generation by atomic clock ...
Abstract: A high-availability and high-stability timescale system, the Rolex Timescale, designed in collaboration between CSEM and METAS for Rolex, has been developed. This system, targeting ...
