S2-PDGS-SYS-320
The PDGS shall be able to perform essential quality-control checks on all the MSI
production to assess the integrity and consistency of the generated product data in terms
of format and contents using simple algorithms.
S2-PDGS-SYS-325
The essential quality-control checks shall be performed immediately following the dataprocessing
activities and before the product data is made accessible externally.
S2-PDGS-SYS-330
The PDGS shall be able to allow or prevent the distribution of the product-data to the
general users based on the results of the essential quality control performed.
S2-PDGS-SYS-335
The PDGS shall be able to report within each delivered product on the results of the
essential quality control checks performed.
S2-PDGS-SYS-340
The PDGS shall be able to autonomously generate the satellite on-board configuration
parameters of the MSI on need basis including the NUC, the IPS, the FEE and the TCM
tables and release them to the FOS for uplink and activation.
S2-PDGS-SYS-345
The PDGS shall be able to autonomously generate or fetch all on-ground processing
configuration data required to perform the data-processing activities including:
All the Level-0 and Level-1 processing parameters modelled as Ground Image
Processing Parameters (GIPP);
All the auxiliary-data required for the MSI processing activities reusing existing
operational data supply services (e.g. ECMWF, IERS, etc).
S2-PDGS-SYS-350
The PDGS shall implement a mechanism in coordination with the FOS to synchronise the
on-board configuration updates for upload and activation on-board. This mechanism shall
ensure that:
Every new on-board configuration is fed to the FOS for update with sufficient time in
advance allowing for the uplink and the on-board activation operations;
The PDGS can unambiguously associate the on-ground configuration parameters to
be used according to the actual on-board configuration at a given sensing orbit.
S2-PDGS-SYS-355
The PDGS shall be able to access and make use of the HKTM decoded by the FOS
(packets and engineering value parameters) on need basis for mission performance
