Resolution 4 of the 18th CGPM

Time comparisons using satellite links

The 18th Conférence Générale des Poids et Mesures

considering

  • that high-precision timing is rapidly becoming an essential part of modern telecommunications,
  • that two-way satellite links allow international time comparisons at very high precision,
  • that it appears possible to exchange pseudo-random-noise timing signals simultaneously but without interference with other uses of the channel,
  • that such pseudo-random-noise techniques also allow high-precision ranging,

recommends that the responsible national and international bodies support experiments over telecommunications satellite links for the study of synchronization techniques by means of pseudo-random-noise modulation within the framework of the international timing programs as part of the generation of International Atomic Time.
