Key facts

  • The second joint ICG-IOAG multilateral cislunar positioning, navigation and timing workshop was held in Vienna on 10 to 13 February 2026. [1]Official
  • The first joint workshop of the two bodies took place on 11 to 13 February 2025. [1]Official
  • The workshop page names lunar reference systems and time systems as its focus and records ICG Working Group L on lunar positioning, navigation and timing. [1]Official

In short

The ICG is where agencies compare notes on lunar navigation and timing in public, through its working group on lunar positioning, navigation and timing and through joint workshops with the Interagency Operations Advisory Group. The address on this page is the IOAG page for the second joint workshop, because the committee's own host site did not answer when we checked it. Nothing decided at these workshops is a standard; they are where positions meet before they are drafted.

Every clock value on this site is a model value computed from published rate figures: no lunar time scale has been realized, and nothing on this page is a reading taken from a clock on the Moon[2]Official. The record itself sits inthe list of organizations, and the wider background is inwhat Coordinated Lunar Time is.

What it decides

  1. Where navigation and space agencies state their positions on lunar reference and time systems before any vote.
  2. Which questions the joint working group treats as open, and who has to answer them.
