TL;DR: In this article, the authors performed a comparison campaign of selected frequency references maintained in their laboratories during about 25 days in October/November 2004, using two-way satellite time and frequency transfer (TWSTFT) in an intensified measurement schedule of 12 equally spaced measurements per day.

TL;DR: A new primary frequency standard, the atomic caesium fountain CSF1, has been put into operation at the Physikalisch-Technische Bundesanstalt (PTB) as mentioned in this paper.

TL;DR: The theoretical background for the different calibration modes applied is summarized and examples of results from the 13 calibration campaigns performed up to now are reported, showing a very good reproducibility at the nanosecond level.

TL;DR: In this paper, the authors demonstrate the capability of accurate time transfer using optical fibers over long distances utilizing a dark fiber and hardware which is usually employed in two-way satellite time and frequency transfer (TWSTFT).
