o On contingency cases of the data-supply operations following nominal real-time data
reception, the operator triggers manually the data-supply operation to trigger the Level-
0 processing activities performed by the DPC function.
o For testing purposes, the operator simulates the raw data supply downstream activities
following a satellite pass acquisition.
6.1.2.5 Simulated Scheduled ISP Supply
This scenario accounts for the operator-driven ISP supply simulations. In support of the
system testing activities, this scenario is used for the activation of the data supply activities
vis-à-vis the DPC function simulating one pass data acquisition from the Sentinel-2
constellation.
It requires that a number of simulated (or previously acquired) satellite pass folders are preloaded
on the front-end equipment such that the data-supply activities can be activated by
automation according to a well-defined agenda.
The following steps are identified for this operation scenario:
1) Through an appropriate HMI, the operator defines the simulation agenda though a preselection
and time scheduling of stored pass folders. The operator can reload
previously defined agendas, modify and/or save new ones for future usage;
2) The operator activates the simulation agenda, scheduling the data-supply interface
mechanisms described in the previous scenarios on each stored pass folder following
the agenda configuration.
6.1.2.6 Archive Interface Operations
This scenario provisions for upload/download file transfer and general housekeeping
operations on the DRX function local archive to upload, download and remove the pass
folders remotely using FTP or SFTP protocols. It is operated interactively from any FTP/SFTP
HMI run from the station operator console or remotely from the RP function using the basic
common mechanisms offered through the FTP/SFTP client programs.
6.1.2.7 Reporting on the Operations
This scenario accounts for the autonomous reporting on the performed operations according
to the configuration. As such, the DRX function generates autonomously a report for every
downlink pass that summarises the main performed activities on data reception and front-end
processing activities.
The DRX reports are autonomously supplied to the MPA function (via the MCC function) for
the assessment on the data-link status, front-end reconstruction, errors occurred, data
reconstruction activities, etc.
