SENTINEL-5 PRECURSOR PAYLOAD DATA GROUND SEGMENT

摘要

The Payload Data Ground Segment (PDGS) for thernSentinel-5 Precursor mission operating the TROPOMIrninstrument is currently being developed at DLRrnOberpfaffenhofen. The PDGS covers the functions ofrnpayload data acquisition, level 0 to level 2 near real-timernand offline processing, re-processing, short- and longtermrnarchiving, product quality and service monitoring. Arnmajor challenge in the PDGS development is the handlingrnof high data rates for processing, transmission andrnarchiving, and the integration of several differentrnprocessing systems.rnThis contribution describes the Sentinel-5 PrecursorrnPDGS concept and architecture, gives an overview on thernsystem requirements and presents the current PDGSrndevelopment status. The ESA Sentinel-5 Precursor to bernlaunched in March 2015 is an important mission for therncontinuous operational remote sensing of the atmospherernfilling the gap between the ENVISAT era and the GMESrnSentinel 5 mission.
