Herstmonceux Space Geodesy Facility

The Space Geodesy Facility near Herstmonceux is a working geodetic observatory associated with the Natural Environment Research Council. Its measurements support precise satellite orbits and terrestrial positioning, combining satellite laser ranging with other geodetic observations and analysis. ILRS identifies its laser station as HERL, station 7840. This identity represents the geodesy facility at its published station position, distinct from the nearby Observatory Science Centre visitor attraction.
