CCTF Working Group on GNSS Time Transfer (WGGNSS)

Terms of reference

The objectives of the CCTF WGGNSS are:

  • to report to the CCTF on the state of the art in GNSS time and frequency transfer and to provide recommendations concerning receiving systems, calibration and data processing;
  • in collaboration with the BIPM, to gather and share the information and the experience on available equipment, characterization of the hardware delays, data processing and scientific results;
  • to maintain contacts with the receiver manufacturers in order to inform them about our needs;
  • to stimulate the collection and analysis of code and carrier phase data from all GNSS constellations;
  • to stimulate the development of calibration procedures in agreement with new GNSS receiving systems;
  • to establish contacts with the parallel scientific communities working on the definition of the receiver output standards;
  • to study the clock results formats in agreement with the user needs.
