This paper provides an overview of the Sentinel-1 Payload Data Ground Segment (PDGS), including the main operational concepts and system layout.
It presents the overall Sentinel-1 PDGS architecture and services allowing as a final objective to provide the core ground segment products to Sentinel-1 users within the expected timeliness and quality. To achieve this goal, a number of functionalities to routinely plan the Sentinel-1 satellite, perform X-Band data acquisition, processing, archiving and dissemination, monitor the long tem instrument performance and ensure products meet the expected quality have been implemented. These functionalities are deployed in the Core PDGS Centres and interfaced with standard services like data downlink and long term archiving.
