The Global Geodetic Observing System (GGOS) is the observing system of the International Association of Geodesy (IAG) and a central interface between the geodetic scientific community and society in general. The main mission of GGOS is to ensure the stability and monitoring of the three fundamental fields of geodesy, namely geometry and kinematics, Earth orientation and rotation, and the gravity field and its variability with the goal to provide geodesy’s contribution to Earth Science and other scientific and applied disciplines. GGOS acts on behalf of the IAG in the Group of Earth Observation (GEO) and actively contributes to the Global Earth Observation System of Systems (GEOSS).

Over the last two years, GGOS has carried out a strategy process which resulted in a comprehensive document “The Global Geodetic Observing System: meeting the requirements of a global society on a changing planet in 2020” (GGOS 2020). As part of this strategy process, the future organization of GGOS has been worked out and recently, GGOS published the Calls for Proposals for four new GGOS components, i.e. the GGOS Coordinating Office and Portal, the Bureau for Networks and Communications, the Bureau for Standards and Conventions, and the Bureau for Satellite Missions.

In this presentation, an overview of GGOS as an observing system and an organization will be given and the current status will be addressed. Particular focus will be on potential contribution to GGOS from the Asia region.
