<strong>GSC</strong> <strong>Sentinel</strong>-2 <strong>PDGS</strong> <strong>OCD</strong><br />

In addition, it hosts the POD function for the generation of the Precise Orbit Determination<br />
products and interfaces with the Off-line POD service (as a specific Expert Team) for the<br />
retrieval of reporting information on the accuracy of the <strong>Sentinel</strong>-2 on-board navigation<br />
solution and the POD products.<br />
Due to the nature of the activities performed in the MPAC (Cal/Val, quality control,<br />
performance assessment, etc.), it is likely that specific on-board parameters hosted only in<br />
the HKTM data could be needed to perform specific investigations. To this end, the MPAC<br />
relies on the FOS – EDDS service for the retrieval of the required decoded HKTM parameters<br />
as explained in the MICD (cf. [RD-06]) and following the mechanisms described in [RD-42].<br />
Access to all the <strong>PDGS</strong> production is performed via the MMUS (client) and DAG functions.<br />
Finally, the MPAC hosts the 2 nd line Support-Desk interface accessible from the MMUS and<br />
CDS 1 st line Support-Desks, as well as priviledged interfaces such as the POM, CNES/CST<br />
and Expert Cal/Val Teams.<br />
