Description
This open access volume contains 23 peer-reviewed papers from the GGHS2024 Gravity, Geoid and Height Systems 2024 Symposium co-organized by the International Association of Geodesy (IAG) Commission2, the International Gravity Field Service (IGFS) and the Global Geodetic Observing System (GGOS). The conference was held in Thessaloniki, Greece, from 4 to 6 September 2024, continuing the long history of IAG gravity field related symposia, which started with GGG2000. 125 abstracts were received, out of which 58 have been scheduled as oral presentations and 67 as posters. 130 participants from 26 countries participated in the conference, out of which 48 (‾38%) were Early Career Scientists (ECS).
