The PDGS shall support during the Commissioning Phase (CP) at least the following
activities and shall be manned accordingly:
Mission Planning, according to a pre-defined observation plan in line with the
Commissioning Plan with the possibility to support additionally on-demand or shortterm
pre-defined observation requests from CNES/CST as necessary.
X/Ka-band data reception, with an increasing data volume during commissioning
phase
Systematic operational data processing of Sentinel-2 Level-0 and gradually higher
level products
Off-line interactive reprocessing for troubleshooting purposes (using a stand-alone
(flexible) version of the operational processor)
Auxiliary data handling and configuration control
Instrument calibration according to CNES/CST inputs and instrument performance
monitoring
Product quality control
Instrument and algorithms calibration & products validation in support to CNES/CST
teams
Verification of the on-board & on-ground payload data handling processes
Characterisation of instrument performance in support to CNES/CST teams
PDGS commissioning of all operational services in particular data-access front-end
services
S2-PDGS-SYS-490
During Commissioning Phase, the PDGS shall receive and use the processing
parameters (GIPP) and on-board MSI configuration parameters (NUC, IPS, FEE, TCM
tables) supplied by CNES/CST.
S2-PDGS-SYS-495
The PDGS shall systematically request a data-acquisition plan for the constellation to
cover nominally:
All land surfaces between 56deg South latitude and 84deg North latitude;
major islands (greater than 100 km2 size), EU islands and all the other small islands
located at less than 20km from the coastline;
