5.2.4 SYSTEM CONTROL FUNCTIONS
5.2.4.1 Mission Configuration Control (MCC) Function
5.2.4.1.1 Function Objectives and High-Level Description
The MCC function is responsible for keeping under controlled environment all relevant
mission reference files. MCC function controls critical configuration and essential operations
information to allow a configuration control on critical parameters and resulting operations.
As such, it is in charge of:
○ Keep under a controlled environment all critical configuration parameters and essential
operation reports into a central repository. Comprehensive management of all
essential configuration and operations data over time;
○ Manage the release of mission reference files updates, providing the functionality to
activate (release) a specific system configuration throughout the distributed PDGS
from a single point. The release and activation implies information delivery to
applicable interfaces in a coordinated manner;
○ File edition capabilities to generate required configuration parameters files (i.e. MCC
function generates some configuration parameters files and others are gathered from
applicable interfaces);
○ Collection of all operation reports derived from configuration gathered from applicable
interfaces. In addition delivery of such operations reports to applicable interfaces in a
coordinated manner (i.e. acknowledged and triggered by the operator) or
autonomously according to configuration (making use of the DC function);
○ Providing query capabilities to the operator on the relevant aspects of the mission
reference files management (e.g. ingestion time, release time, applicability time, etc.);
5.2.4.1.2 Design Drivers and Constraints
The following drivers and constraints are identified:
○ Single point for the PDGS relevant parameters configuration management and
release;
○ Usage of the DC function for required data circulation activities;
5.2.4.1.3 Function Interfaces
The following function interfaces are identified for the MCC function:
○ MSI on-ground and on-board configuration gathered from the applicable interfaces
(e.g. NUC tables and GIPP provided by the CNES/CST during the phase-E1 and the
PDGS/MPA function during the phase-E2);
○ Operation information and reports gathered from applicable interfaces (e.g. AI function
archive reports);
