Gravity, Geoid, and Height Systems 2022 Symposium

GGHS2022: Gravity Geoid and Height Systems 2022

Given the responses to date, we will be able to fit the meeting into three days – the Symposium will be conducted from Monday September 12 through Wednesday September 14. This may help you finalize your travel program appropriately.

The 3rd joint meeting of the International Gravity Field Service and Commission 2 of the International Association of Geodesy will be held in Austin, Texas USA, Sep 12-14, 2022.

This meeting was originally planned for the same time in 2020, but was cancelled and and rescheduled to 2022. The meeting will be held in a hybrid format. The remote attendees will be able to join the oral sessions (Live) using Zoom and engage fully in the Q&A. For the remote speaker (e.g. oral and spotlight session), other than the usual Zoom option, the pre-recorded video option is under discussion. We are exploring all options to engage remote attendees on poster sessions.


The science of the earth’s gravity field and its time variation is advancing rapidly. In addition to the classical disciplines of geoid determination, geodetic reference systems, navigation, satellite orbit determination, and geophysics and interior earth structure, the gravity field science has in the last decade provided unique insighhts into the cryosphere and hydrological changes, and general mass transports in the earth system, primarily from GRACE and GRACE-FO satellite missions. At the same time global knowledge of the gravity field details has improved significantly due to the GOCE mission, large-scale airborne gravity campaigns, and the coverage of the oceans by satellite altimetry. New technologies such as cold atom interferometry, miniature gravity sensors, strapdown IMU gravity sensors, and new satellite mission concepts are on the poise to further advance gravity field science.

The GGHS2022 symposium aims to bring together geodesists, geophysicists and space scientists who work with gravity field observations from space, airborne and surface, novel gravity field observation technologies, gravity field modelling, fundamental height systems, gravity networks, and gravity field change observations for climate change and hydrology.

The GGHS2022 is hosted by Center for Space Research, The University of Texas at Austin. This follows the successful symposia GGHS2018 in Copenhagen, Denmark and GGHS2016 in Thessaloniki, Greece, and a long prior sequence of biennial International Association of Geodesy/International Gravity Field Service meetings since 2000.

The symposium sessions will be structured around several broad themes:

  • Global gravity field modelling
  • Local/regional gravity field modelling
  • Absolute, Relative and Airborne Gravity – observations and methods
  • Height systems and vertical datum unification
  • Modern technologies for gravity field sensing – terrestrial, airborne, or spaceborne
  • Current and future satellite gravity missions
  • Satellite altimetry and applications
  • Mass transport and climate-relevant processes
