Webinar: The new International Gravity Reference System (IGRS) and its materialization (IGRF)

Abstract: The increasing importance of terrestrial gravimetry requires a stable reference system that reflects the precision achieved by modern gravimeters. Over the past decade, the International Association for Geodesy (IAG) has developed a system for achieving accurate, homogeneous, long-term global monitoring of the Earth’s gravity field, while harnessing the potential of current absolute gravity measurements. […]
