S2-<strong>PDGS</strong>-SYS-035<br />
The <strong>PDGS</strong> shall be able to preserve in dedicated long-term archives, all the <strong>Sentinel</strong>-2<br />
Level-0 product data (HKTM and MSI) together with all the associated ancillary/auxiliary<br />
data, critical software and documentation required for higher-level processing, during the<br />
whole <strong>PDGS</strong> operational lifetime.<br />
S2-<strong>PDGS</strong>-SYS-040<br />
The <strong>PDGS</strong> shall be able to preserve in the long-term archives a predefined set of<br />
<strong>Sentinel</strong>-2 high level products, including the related auxiliary data, during the whole <strong>PDGS</strong><br />
operational lifetime.<br />
S2-<strong>PDGS</strong>-SYS-045<br />
The <strong>PDGS</strong> shall be able to elaborate systematically all the MSI raw data into elaborated<br />
Level-0, Level-1 and True Colour Image (TCI) products by means of a network of<br />
processing centres or directly at the CGSs.<br />
S2-<strong>PDGS</strong>-SYS-050<br />
The <strong>PDGS</strong> shall be able to generate systematically the <strong>Sentinel</strong>-2 true-colour images<br />
(TCI) at full spatial resolution as part of its nominal data-processing activities. The<br />
activation of the TCI systematic generation shall be configurable.<br />
S2-<strong>PDGS</strong>-SYS-055<br />
The TCIs processing performed by the <strong>PDGS</strong> shall be optimised towards the generation<br />
of visually attractive and eye-catching images.<br />
S2-<strong>PDGS</strong>-SYS-060<br />
The <strong>PDGS</strong> shall be able to generate systematically the Precise Orbit Determination (POD)<br />
products by processing the satellite on-board navigation data provided in the satellite<br />
ancillary data.<br />
S2-<strong>PDGS</strong>-SYS-065<br />
The <strong>PDGS</strong> shall be able to use the POD products for processing the MSI data in case of<br />
contingency with the on-board navigation solution.<br />
S2-<strong>PDGS</strong>-SYS-070<br />
The <strong>PDGS</strong> shall be able to use the <strong>Sentinel</strong>-2 MSI Decompression Software as part of<br />
Level-1 processing activities to decompress the MSI raw image data.<br />
S2-<strong>PDGS</strong>-SYS-075<br />
The <strong>PDGS</strong> shall ensure, by implementing appropriate mechanisms in the MSI dataelaboration<br />
chain from Level-0 to Level-1 and TCI processing cascading from every<br />
satellite acquisition, that the elaborated data is timely available to the downstream<br />
