S2-PDGS-DPC-135
The PDGS/DPC function shall be able to define and manage new processing tasks and
workflows by configuration.
S2-PDGS-DPC-140
The PDGS/DPC function shall be able to organize and orchestrate in a data-driven way
the execution of the configured processing tasks based on new input data availability.
S2-PDGS-DPC-145
The PDGS/DPC function shall be able to trigger different workflows depending on the MSI
sensing mode reported in the telemetry. For instance, it shall be possible to by-pass IDP
processing steps or quality control checks on dark-calibration images.
S2-PDGS-DPC-150
The PDGS/DPC function shall be able to select the processing parameters applicable to
the processing workflows as a function of the MSI configuration reported in the telemetry.
For instance, it shall be possible to select the applicable GIPP configuration based on the
NUC table identifier reported in the MSI packets.
S2-PDGS-DPC-155
The PDGS/DPC function shall be able to manage simultaneously different versions of the
same processor such that different versions of a data processor can run concurrently and
be managed independently.
S2-PDGS-DPC-160
The PDGS/DPC function shall be able to insert breakpoints in the processing workflows
and allow interactive inspection of temporary intermediate results at the defined
breakpoints for debugging or verification purposes.
S2-PDGS-DPC-165
The PDGS/DPC function shall be able to perform bulk-reprocessing activities
automatically after triggering by the operator.
S2-PDGS-DPC-170
The PDGS/DPC function shall be able to trigger the bulk reprocessing activities in either
ascending or descending order of sensing-orbit.
S2-PDGS-DPC-175
The PDGS/DPC function shall allow the operator to trigger the contingency reprocessing
of a satellite pass processing after a general failure occurring on the nominal processing
workflow. It shall be possible to trigger the recovery processing either:
from DRX deferred input in case of a contingency occurring during the real-time frontend
processing;
