S2-<strong>PDGS</strong>-MPL-485<br />
The <strong>PDGS</strong>/MPL function shall constrain the Downlink-Plan activities by the X-Band &<br />
ground stations time slots assigned to other <strong>Sentinel</strong>s Missions. The S-2 <strong>PDGS</strong> shall be<br />
able to share common ground-station resources with the other <strong>Sentinel</strong> Missions.<br />
S2-<strong>PDGS</strong>-MPL-490<br />
The <strong>PDGS</strong>/MPL function shall constrain the Downlink-Plan activities by the EDRS GEO<br />
Availability Segments assigned to the <strong>Sentinel</strong>-2 Mission.<br />
S2-<strong>PDGS</strong>-MPL-495<br />
The <strong>PDGS</strong>/MPL function shall provide the Mission-Plan (i.e. the image plan and the<br />
Downlink-Plan) in a single physical file according to the <strong>PDGS</strong>-FOS ICD.<br />
S2-<strong>PDGS</strong>-MPL-500<br />
The <strong>PDGS</strong>/MPL function shall generate the ground station schedule plan using the most<br />
accurate orbit information available.<br />
S2-<strong>PDGS</strong>-MPL-505<br />
The <strong>PDGS</strong>/MPL function shall generate the ground stations schedule plan (data reception<br />
and processing events) individually per each involved ground station.<br />
(AOS, LOS, FEP start processing, FEP stop processing events, etc. shall be separated<br />
per each involved station).<br />
S2-<strong>PDGS</strong>-MPL-510<br />
The <strong>PDGS</strong>/MPL function shall generate a local report on every manual or automatic<br />
planning activity triggered.<br />
S2-<strong>PDGS</strong>-MPL-515<br />
The <strong>PDGS</strong>/MPL function shall alert the operator on the failed automatic plan generation<br />
activities through M&C capabilities.<br />
5.17.4 RAMS REQUIREMENTS<br />
S2-<strong>PDGS</strong>-MPL-520<br />
The <strong>PDGS</strong>/MPL function shall ensure nominal operations unattended for better than<br />
99.7% of the time computed over one month time window and assuming a degradation of<br />
such figure for no more than one day.<br />
S2-<strong>PDGS</strong>-MPL-525<br />
The <strong>PDGS</strong>/MPL function shall ensure that the all the satellite / payload commanding<br />
activities are fulfilling the Spacecraft Operations Constraints defined in [SOCD].<br />
