31

Monitoring

Central, integrated, and complete model of the monitored and controlled system (live mode)

Improved extensibility to allow easy addition of new data types

New input packet type "variable list" to allow ingestion of parameter values in a change based manner

Hierarchical structuring of the monitoring model by introduction of container objects (“system elements”) and structured names

Global acknowledgement of the system alarms status via a central display

32

Schedule processing

Use of MATIS (Mission Automation System)Addition of the notion of an operational session (e.g. spacecraft pass) to the MATIS calendar layerSupport for correlation of schedules with sessions / passesEditing of event / pass definitionsNew extension points to the MATIS MMI to allow for addition of pass related activities in GSMC

Pluto procedure high-level control activity

33

Low-level procedures - Script execution

Integrated script execution environment based on JavaScript

Wide spread scripting language

Can combine low level commands to higher level control sequences that can be invoked via the MMI or by MATIS

34

Control activity

For the script execution and the schedule execution:

“Control activity” data for execution history recording and display (cf. command history display)

“Automation message” for event logging

35

Man Machine Interface

Based on EGOS User Desktop (EUD)- Eclipse technology

Including mimic capability

B- GSMC tailoring subsystem

Generic tailoring system for spacecraft M&C system and ground station M&C system does not appear to be feasible

Baseline: – GSMC Tailoring System based on a generic framework for

Database Manager (DABYS)– Re-use the current Eclipse-based MMI (OTTO, Operational

Tailoring Tool)– Make OTTO available to the online subsystem to support “online

tailoring”

44

Tailoring migration

Tools for automatic conversion of existing tailoring as far as possible:

Parameters model

Automatic conversion + manual actions

Procedures

Fully automated conversion of existing procedures to JavaScript

Offline consistency check tool

MMI

EGOS User Desktop

Conversion for Alpha Numeric Displays
