Liaison: International Committee on Global Navigation Satellite Systems (ICG)


Links between the BIPM and the ICG

  • The BIPM is an observer of the ICG.
  • Dr Gérard Petit (BIPM Time Department) is the BIPM delegate at the ICG and is the chair of the ICG Task Force on Time References.


The ICG, established by the United Nations, strives to encourage and facilitate compatibility, interoperability and transparency between all the satellite navigation systems, to promote and protect the use of their open service applications and thereby benefit the global community.

The BIPM and the ICG cooperate to promote the use of global navigation satellite systems (GNSS) infrastructure on a global basis, particularly in timing applications, and to promote the regular use of metrology standards. Most actions of the BIPM are related within the ICG Working Group D - Reference Frames, Timing and Applications.
