BIPM Workshop on Advanced Time and Frequency Transfer (ATFT): the ultimate frontier for remote comparison methods
10 October 2019 at the BIPM
Davide Calonico CCTF-WGATFT Chair

Joachim Ullrich CCU President
Noël Dimarcq CCTF President

Organizing committee:
Gianna Panfilo CCTF-WGATFT Secretary
Patrizia Tavella CCTF Executive Secretary
Estefanía de Mirandés CCU Executive Secretary

Objective of the workshop:

    The Consultative Committee for Time and Frequency Working Group on Coordination of the Development of Advanced Time and Frequency Transfer Techniques (CCTF-WGATFT), in cooperation with the Consultative Committee for Units (CCU), is organizing a workshop with the aim of bringing together different communities to explore the limits of time and frequency transfer in view of a possible redefinition of the second.

    Time and frequency transfer methods are key matters within the time and frequency community. The main goal of the workshop is to explore technical advancements in time and frequency transfer as well as related fields outside of this domain.

    Time and frequency transfer is widely used in many scientific fields, such as astronomy, telecommunications, space applications, and geodesy, with different levels of relationships with the time and frequency community. The need for high-performing techniques in the time and frequency domain encourages the exploration of these different fields of application to bring together experiences and knowledge.

    The first part of the workshop will be dedicated to invited talks and the second part will be followed by a panel discussion on the ultimate frontier for remote comparison methods.

    Proposed discussion topics:

    1. Introduction of CCTF-WGATFT activities
    2. Optical two-way time and frequency transfer over free space
    3. Radio astronomy techniques
    4. Synchronization of telecommunication networks
    5. Coherent frequency transfer using optical fibres
