The High-level Processing Facility (HPF) is part of the GOCE Ground Segment and is developed under ESA contract by the European GOCE Gravity consortium (EGG-c). The HPF is set up as a distributed facility consisting of several sub-processing centers for scientific pre-processing, orbit determination, gravity field analysis and validation. The sub-processing facilities are connected through a kind of internal HPF-network through a central node which is called the Central Processing Facility (CPF). This CPF is the single point of interface between HPF and ESA's Ground Segment (for the latter this is the Payload Data Center (PDS)). The tasks of the CPF are: to collect all data necessary for high-level processing, this includes Level 1b data products from the PDS and auxiliary data products from external data providers; to convert these input data to a dedicated internal HPF format; to distribute these data, and Level 2 intermediate and final products, within the HPF using a full-fledged data base facility; to formally check all L2 products on format, validity and content; to monitor the whole data distribution chain; and to distribute all L2 data to ESA for storage and archiving and use by end users. This poster will illustrate the design and operation of the CPF in its HPF context and indicate the specific monitoring, validation and control activities the CPF performs to support the quality of the final data products.
