GGRF – Global Geodetic Reference Frame

The GGRF is a globally unified geodetic reference system providing accurate coordinates, heights, and gravity information anywhere on Earth. It integrates geometric positioning and gravity field observations to enable consistent, interoperable geospatial data for science, society, and sustainable development. The GGRF underpins satellite navigation, Earth observation, disaster management, and monitoring of climate and sea-level changes.
