SUMMARY:PhHS-IHRF2026 - Int. Symposium on Physical Height Systems and the IHRF
DESCRIPTION:⚠️⚠️Given the recent evolving circumstances in the Middle East\, we would like to let you know that the IAG SC2.2\, SC2.4\, IGFS and GGOS Symposium “Physical Height Systems and the International Height Reference Frame – PhHS–IHRF2026” will be postponed to a future date. As the situation is quite uncertain\, no plans have been made yet\, hence we will keep you updated. Apologies for the last-minute change and any inconvenience this may cause to your schedule. ⚠️⚠️ \nThe PhHS-IHRF2026 “International Symposium on Physical Height Systems and the International Height Reference Frame” will be held in Riyadh\, Kingdom of Saudi Arabia from 7 to 9 April 2026. It focuses on methods for observing\, estimating and interpreting the Earth’s gravity field and the geoid with special emphasis on height systems\, physical height determination and the realization of the International Height Reference System (IHRS) into the International Height Reference Frame (IHRF). PhHS-IHRF2026 is a Joint IAG Symposium co-organized by IAG SC2.2 “Geoid\, Physical Height Systems and vertical datum unification”\, SC2.4 “Gravity and Geoid”\, the International Gravity Field Service (IGFS) and the Global Geodetic Observing System (GGOS). \nOfficial Symposium Website: https://geosa.gov.sa/en/Pages/phhs-ihrf-2026.aspx \n \nScientific Organizing Committee: \nGeorge Vergos (SC2.2 Chair\, IHRF CC director\, IGFS CB Director)\nRossen Grebenitcharsky (SC2.2 Vice-Chair)\nRiccardo Barzaghi (IGFS President)\nLaura Sanchez (GGOS President)\nHussein Abd-Elmotaal (SC2.4 Chair)\nRene Fordberg\nZuheir Altamimi  \nLocal Organizing Committee: \nAlShahrani Sultan Falah\nMohammed AlArjani\nMashael AlHarbi\nSaad AlQahtani\nAbdulmohsen AlDosari\nSaleh AlFaris\nEslam Abdulsamie
