Explicit Ensemble Mean Synchronization for Time Scale Generation with Mixed Atomic Clock Ensembles
Priyanka Dey, Takahiro Kawaguchi, Yuichiro Yano +2
In this paper, we consider a mixed ensemble containing a mixture of cesium-type and hydrogen maser-type atomic clocks. For the mixed ensemble, the conventional Kalman filtering alg…
Optimal GNSS Time Tracking for Long-term Stable Time Realisation in Synchronised Atomic Clocks
Maitreyee Dutta, Jiayu Chen, Masakazu Koike +3
In this manuscript, we propose a novel optimal Global Navigation Satellite System (GNSS) time tracking algorithm to collectively steer an ensemble consisting of synchronising minia…
Hierarchical Distributed Architecture for the Least Allan Variance Atomic Timing
Jiayu Chen, Takahiro Kawaguchi, Yuichiro Yano +2
In this paper, we propose a hierarchical distributed timing architecture based on an ensemble of miniature atomic clocks. The goal is to ensure synchronized and accurate timing in…
Explicit Ensemble Mean Clock Synchronization for Optimal Atomic Time Scale Generation
Takayuki Ishizaki, Takahiro Kawaguchi, Yuichiro Yano +1
This paper presents a novel theoretical framework, called explicit ensemble mean (EEM) synchronization. This framework unifies time scale generation, clock synchronization, and osc…
