Recommendation-CIPM-1993-3

Recommendation 3 of the 82nd CIPM (1993)

Clock comparison by satellite laser techniques

The Comité International des Poids et Mesures,

considering

  • the need for long distance time transfer at the highest possible level of accuracy,
  • that successful time transfer with a precision of 100 ps has been achieved between Western Europe and North America using LASSO (Laser Synchronization from Satellite Orbit) experiment,
  • that time transfer techniques, such as GPS (Global Positioning System), GLONASS (Global Navigation Satellite System) and two-way satellite time transfer, need an independent means of assessment of their accuracy,
  • that solutions have been proposed that may lead to dock synchronization by laser techniques using non-geostationary satellites,

recommends that the space agencies consider the installation on their satellites of appropriate equipment for dock comparison by satellite laser techniques.
