S2-<strong>PDGS</strong>-DPC-085<br />
The <strong>PDGS</strong>/DPC function shall accept incoming connection(s) from the DRX function to<br />
trigger the real-time reception of MSI, Satellite Ancillary and HKTM data.<br />
S2-<strong>PDGS</strong>-DPC-090<br />
The <strong>PDGS</strong>/DPC function shall process in real-time the flows of MSI ISPs and Satellite<br />
Ancillary Data ISPs as part of the MSI L0 generation activities.<br />
S2-<strong>PDGS</strong>-DPC-095<br />
The <strong>PDGS</strong>/DPC function shall process in real-time the flow of HKTM Transfer Frames as<br />
part of the HKTM L0 generation activities.<br />
S2-<strong>PDGS</strong>-DPC-100<br />
The <strong>PDGS</strong>/DPC function shall provide the generated L0 PDIs (i.e. S2MSI0 & S2HKTM)<br />
for archiving to the AI function in real-time.<br />
S2-<strong>PDGS</strong>-DPC-105<br />
The <strong>PDGS</strong>/DPC function shall be able to divide the input data flow into independent parts<br />
of a configurable size to parallelise the processing activities according to a well-defined<br />
parallelisation strategy.<br />
S2-<strong>PDGS</strong>-DPC-110<br />
The <strong>PDGS</strong>/DPC function shall organize and orchestrate the execution of the different<br />
processing activities within a well-controlled process workflow.<br />
S2-<strong>PDGS</strong>-DPC-115<br />
The <strong>PDGS</strong>/DPC function shall orchestrate the execution of the different tasks optimising<br />
the available HW resources.<br />
S2-<strong>PDGS</strong>-DPC-120<br />
The <strong>PDGS</strong>/DPC function shall be able to manage the processing of several MSI data<br />
fragments in parallel.<br />
S2-<strong>PDGS</strong>-DPC-125<br />
The <strong>PDGS</strong>/DPC function shall be able to manage the processing of several QC postprocessing<br />
activities in parallel.<br />
S2-<strong>PDGS</strong>-DPC-130<br />
The <strong>PDGS</strong>/DPC function shall be able to trigger and manage the systematic execution of<br />
IDP processing tasks to perform L0 consolidation processing, L1 processing, and TCI<br />
processing workflows.<br />
