Relations Between Generalized JST Algorithm and Kalman Filtering Algorithm for Time Scale Generation
Yuyue Yan, Takahiro Kawaguchi, Yuichiro Yano +2
In this paper, we present a generalized Japan Standard Time algorithm (JST-algo) for higher-order atomic clock ensembles and mathematically clarify the relations of the (generalize…
Roadmap towards the redefinition of the second
N. Dimarcq, M. Gertsvolf, G. Mileti +34
This paper outlines the roadmap towards the redefinition of the second, which was recently updated by the CCTF Task Force created by the CCTF in 2020. The main achievements and the…
Structured Kalman Filter for Time Scale Generation in Atomic Clock Ensembles
Yuyue Yan, Takahiro Kawaguchi, Yuichiro Yano +2
In this article, we present a structured Kalman filter associated with the transformation matrix for observable Kalman canonical decomposition from conventional Kalman filter (CKF)…
Higher-Order Allan Variance for Atomic Clocks of Arbitrary Order: Mathematical Foundation
Takayuki Ishizaki, Taichi Ichimura, Takahiro Kawaguchi +2
In this paper, we perform a time-domain analysis of the higher-order Allan variance for atomic clock models of arbitrary order. Adopting a standard atomic clock model where the tim…
