S2-<strong>PDGS</strong>-DPC-040<br />
The <strong>PDGS</strong>/DPC function shall be able to identify the different MSI scene segments<br />
received during the same satellite pass according to the scenes sensing time.<br />
S2-<strong>PDGS</strong>-DPC-045<br />
The <strong>PDGS</strong>/DPC function shall be able to receive and process the satellite ancillary data<br />
ISPs.<br />
S2-<strong>PDGS</strong>-DPC-050<br />
The <strong>PDGS</strong>/DPC function shall manage the data overlaps introduced in the satellite<br />
ancillary data downlinks throughout the CGS network.<br />
S2-<strong>PDGS</strong>-DPC-055<br />
The <strong>PDGS</strong>/DPC function shall be able to receive and process the X-Band HKTM Transfer<br />
Frames.<br />
S2-<strong>PDGS</strong>-DPC-060<br />
The <strong>PDGS</strong>/DPC function shall generate the L0 MSI PDIs from the received mission and<br />
satellite ancillary data ISPs and safeguard them in the local archive through the AI<br />
function capabilities for further processing.<br />
S2-<strong>PDGS</strong>-DPC-065<br />
The <strong>PDGS</strong>/DPC function shall generate and safeguard the L0 HKTM (S2HKTM) product<br />
data items from the received stream of X-Band HKTM Transfer Frames and safeguard<br />
them in the local archive through the AI function capabilities for further processing.<br />
S2-<strong>PDGS</strong>-DPC-070<br />
The <strong>PDGS</strong>/DPC function shall generate the S2MSI0 PDIs from the received MSI and<br />
satellite ancillary ISPs according to the S-2 <strong>PDGS</strong> Product Definition Document (e.g. each<br />
S2MSI0 PDI will correspond to a single detector and single scene comprehensive of all<br />
bands).<br />
S2-<strong>PDGS</strong>-DPC-075<br />
The <strong>PDGS</strong>/DPC function shall flag the MSI downlink operation mode (RT, NRT or<br />
nominal) within the generated S2MSI0 PDIs.<br />
Comment: This is required for <strong>PDGS</strong> operations timeliness monitoring.<br />
S2-<strong>PDGS</strong>-DPC-080<br />
The <strong>PDGS</strong>/DPC function shall flag the MSI acquisition mode within the generated S2MSI0<br />
PDIs. As such, S2MSI0 PDIs shall be flagged as nominal observation, extended<br />
observation, dark signal calibration, absolute radiometric calibration, etc accordingly.<br />
