我们描述了法国时标 UTC(OP) 自 2012 年 10 月设计变更以来的运行和性能。新的 UTC(OP) 基于使用 LNE-SYRTE 原子喷泉频率校准控制的主动 H 微波激射器。后来，发电和配电系统被完全重建，以提高短期稳定性和时间尺度的鲁棒性并提供冗余。通过新设计，UTC(OP) 在几纳秒内仍然接近 UTC。本文主要关注时间尺度的表现以及遇到的重大事件。
We describe the operation and the performances of the French time scale UTC(OP) since the change of its design in October 2012. The new UTC(OP) is based on an active H-maser steered using LNE-SYRTE atomic fountains frequency calibrations. Later on, the generation and distribution systems were entirely rebuilt to improve the short term stability and the robustness of the time scale and to provide redundancy. With the new design, UTC(OP) remains close to UTC within a few ns. This paper is focussed on the performances of the time scale and on the major events encountered.
