EUMETSAT Headquarters and Mission Control in Darmstadt is the operational centre for Meteosat geostationary and Metop polar-orbiting fleets and supports Copernicus satellite operations and near-real-time weather, climate and environmental data services. EUMETSAT’s current ground-segment description identifies separate control rooms for geostationary and low-Earth-orbit missions and says the associated ground infrastructure is operated from the Darmstadt headquarters. The operator publishes the address as Eumetsat-Allee 1, 64295 Darmstadt, Germany. This is an active operational headquarters; the current contact page provides directions but no general walk-in or current public-tour route, so contact EUMETSAT before planning a visit and do not assume access.
