GSC Sentinel-2 PDGS OCD Issue 1 Revision 2 (draft) - 25.07.2010 GMES-GSEG-EOPG-TN-09-0008 page 254 of 350 6.2.3.2 Current Downlink-Pass Level-0 Generation This scenario stands for the autonomous and data-driven and on-the-flow L0 products generation activities correspondent to the current downlink pass. The DPC function interfaces with the DRX function as the supplier of the current downlink pass ISPs raw data (cf. section 6.1.2.3 - Current Pass Data-Reception and Real-Time ISP Supply). Subsequently to the L0 product data items generation, the DPC function invokes the AI function for the archiving. This processing is performed on-the-flow by way of well defined processing units of fixed sizes for the MSI. This processing is performed in a data driven mode as triggered by the DRX function on reception of data from the satellites. The uses cases of this scenario are nominal L0 processing activities such as: ○ S2HKTM generation; ○ L0 satellite ancillary data generation; ○ L0 MSI data generation. 6.2.3.3 Previous Downlink-Pass Level-0 Generation This scenario stands for the operator-driven L0 products generation of a previous downlinkpass in response to potential contingencies. The DPC function will interface with the DRX function and accordingly make use of the supported mechanisms for the previous-pass data forwarding (cf. section 6.1.2.4). This scenario only differs from the previous one in the operator-driven activation. Once the operator has triggered the raw data ISPs forwarding from the DRX function to the DPC function, the latter performs the level-0 processing activities according to the configuration as explained previously. The uses cases of this scenario are the L0 reprocessing activities for contingency such as: ○ S2HKTM generation; ○ L0 satellite ancillary data generation; ○ L0 MSI data generation. 6.2.3.4 Data-Driven Processing Orchestration This scenario corresponds to the autonomous orchestration, commanding and control of the different processing activities according to the new input data availability. The DPC function on a data-driven manner, starting from the new L0 data trunks availability orchestrates the generation activities of the MSI higher level products data. As such, the DPC function interfaces with the IDP & OLQC functions, which are in charge of the MSI L1A, L1B, L1C, True Colour Image product data generation and associated QC activities respectively. The DPC function according to the configuration chains the different processing activities allowing the execution of multiple and simultaneous activities. The use cases of this processing scenario are orchestration of the following activities: ESA UNCLASSIFIED – For Official Use © ESA The copyright of this document is the property of ESA.

There are different use cases envisaged for this operation scenario such as: ○ New processors verification and validation (e.g. in the MPA centre); ○ Recovery from a failed data-processing; ○ The reprocessing of all the product-data acquired/generated during the commissioning phase. The operator defines the commissioning phase set of orbits and the DPC function queues and orchestrates the appropriated processing jobs. 6.2.3.6 Hosted-Processing Requests Processing Orchestration This scenario corresponds to the user-requests-driven orchestration, commanding and control of the hosted-processors. The DPC function will offer an interface towards the DAG function for the submission of the hosted-processing user requests and the subsequent processing management activities. The use case of this scenario is the hosted-processing activities as requested by the users through the MMUS function and routed by the DAG function to the local DPC function. 6.3 Instrument Data Processing (IDP) Operations 6.3.1 PRINCIPLES The PDGS/IDP function is a collection of processing modules in charge of processing the instrument and satellite telemetry to generate the product data items (PDIs) that will compose Level-0 consolidated, Level-1A, Level-1B, Level-1C and True Colour Images products. Each IDP function processing module can read input data from files and output its results to (newly generated) files. The IDP function processing elements can be chained so that the output of one task can be input to other tasks in the calling sequence. The IDP function main processing steps are summarized in Figure 4-23. It is highlighted that the last step from Level-1C to Level-2A will be carried out through an independent IDP function triggered interactively via the PDGS hosted processing functionality. Due to the huge volume of data to generate the MSI data production, the processing activities performed by the IDP function are envisaged to be on the flow, thus the IDP function will process MSI data linearly and systematically as available. © ESA The copyright of this document is the property of ESA.
