Positioning exact to the millimeter: Geodetic reference syst
Science Daily GeologyHow many millimeters has the sea level risen? How fast are the continents moving? In order to answer these questions, measurements are being made around the clock at more than 1,700 globally distributed observing stations. These data are then evaluated by researchers. Their new realization of the global reference system that has now been published, is so exact that it even allows to detect seasonal variations.
