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;
  • to propose and organize novel comparison and calibration campaigns, including multiple techniques (such as GNSS, TWSTFT, ACES microwave link, T2L2, optical fibre links).
