Data Acquisition within the EO Ground Segment
Development of Global Payload Ground Station Network to serve mission needs: near real time data acquisition and processing, fast access to data, remote control of receiving stations
New technology concepts for data reception: higher data rates and usage of optical communication technology
Stations are embedded in overall system operations for ordering, reception and distribution of payload data from national, European and international EO missions
Engineering und system integration of EO ground segments is performed for national (TerraSAR-X, TanDEM-X, EnMAP, etc.) and European (e.g. Sentinel) missions
