The basic idea is to increase more and more the use of conceptual models that describes and represents, in various ways, the systems operated through our monitoring and control systems. The use of models can be beneficial in multiple ways, such as for simplifications, for more consistencies or for more commonalities across systems. Currently, for example, Spacecraft Monitoring & Control depends very much on the actual spacecraft design and can vary a lot from spacecraft to spacecraft. This results in a high effort for training and re-training the Flight Control Team members and makes it difficult to share SPACONS across missions. Applying more abstract models can, to some extent, be used to harmonise Spacecraft and Ground Systems Monitoring & Control. This approach is highly supported by mission operators. Monitoring & Control Models (MCMs) have always been used in operation. However, those have been typicallydefined at very low level of abstraction (e.g. the commanding stack model of the mission control system or the alphanumeric displaymodels (ANDs) for monitoring). Higher level of abstraction and integration of models only starts to be applied in the operation automation systems and are already more used in the M&C systems for the ground stations and related back-end systems. The MCM of futureMCS/EGSE systems will be based on the ECSS-E-ST-70-32C concepts, which include concepts of system of systems modelisation using various layers of details (but with fractal-like property. i.e. identical at all scales). However, these systems will define only the execution model (i.e. how one interacts with the systems under control. i.e.. The abstracted concepts which are used to execute the operations). How one design and plan the abstract models of the systems is yet to be investigated and developed. Overall, the questions to be answered by this study are: How can we, in a simple way, allow the operators to – use a coherent and integrated model (of models) of their whole domain of operation? – define the models used by their mission, based or re-using generic models? – model the dynamic and relationships of the systems (including flow of information and change of states) related to M&C in their mission in an integrated way? The study shall at least: a/ Analyse & define suitable M&C Model design methodologies and techniques including planning and taking the EGS-CC Execution MCM as a potential demonstrator. b/ Exercise selected methodologies to selected parts of the systems and sub-systems. c/ Demonstrate, through software prototyping, visual and non-visual definition and interactions with the models, including actual execution up to the real systems.
