CCTF Working Group on Coordination of the Development of Advanced Time and Frequency Transfer Techniques (WGATFT)

Terms of reference

  • to review the status and projected evolution of the characteristics of frequency,
  • standards, time scales and time and frequency transfer techniques,
  • to follow and assess the evolution of microwave links in current use, based on GNSS signals and TWSTFT,
  • to follow and assess other technical possibilities, including optical fibre links, optical satellite links, and transportable optical frequency standards, which could be used for comparison of high performance frequency standards,
  • to establish the relevant connections and facilitate consultations with other relevant bodies, such as IGS, IUGG, IVS, ITU, etc.
  • together with BIPM, to foster the spread of information on technical achievements by suitable means, e.g. workshops, and
  • to propose and organize novel comparison and calibration campaigns, including multiple techniques (such as GNSS, TWSTFT, ACES microwave link, T2L2, optical fibre links).
