Abstract

Abstract: From July 11 to 20, 2023, the 28th International Union of Geodesy and Geophysics (IUGG) general assembly was held in Berlin, Germany. According to the tradition of IUGG, the Chinese National Committee for International Association of Geodesy (CNC-IAG) organized dozens of domestic institutions to compile the “2019—2023 China National Report on Geodesy”, which summarized the research progress of various branches of geodesy in China from 2019 to 2023. This article summarizes the overall progress of China's geodetic discipline in recent years, focusing on representative progress in six research directions including reference frame, comprehensive PNT and resilient PNT, gravity field and vertical datum, precise GNSS products, multi-source sensor integrated navigation, and marine geodesy. Moreover, in light of the development trends of international geodesy and related interdisciplinary disciplines, several suggestions are proposed for the future development of geodesy in China.

Key words: IUGG, reference frame, PNT, gravity field, vertical datum, navigation and positioning, marine geodesy
