In this paper a new algorithm for the introduction of redundant time links in UTC calculation is presented. This algorithm is first applied for the evaluation of the uncertainty of [UTC-UTC( k )] reported in section 1 of Circular T . We show that it solves several limitations of the current method used to evaluate the uncertainties. In particular it facilitates the introduction of correlations, it allows increasing the calibration uncertainty assigned to uncalibrated laboratories without affecting the other laboratories, and obtaining a more realistic value for the uncertainty of [UTC-UTC( k )] for the present pivot (PTB). The next steps of the project concerning the use of redundant time links in UTC are also discussed.

引入冗余时间链路以生成UTC的第一步：[UTC-UTC（k）]的不确定性计算

本文提出了一种在UTC计算中引入冗余时间链接的新算法。该算法首先用于评估T通告第1部分中报告的[UTC-UTC（k）]的不确定性。我们表明，它解决了当前用于评估不确定性的方法的一些局限性。特别是，它有利于引入相关性，它允许增加分配给未校准实验室的校准不确定度，而不会影响其他实验室，并且可以为当前枢轴（PTB）的[UTC-UTC（k）]不确定度获得更现实的值。还讨论了有关在UTC中使用冗余时间链接的项目的后续步骤。
