IAG Joint Working Group 2.1

Relativistic Geodesy: Towards a new geodetic technique

The International Association of Geodesy (IAG) Joint Working Group (JWG) 2.1 has been established in 2016 to bring together experts from geodesy and time/frequency metrology to review and develop concepts and ideas on relativistic geodesy. The group activities are triggered by the recent fundamental progress both in atomic clocks and in long-distance frequency transfer.

On this website, the group shares information on its activities and related topics.
