7. Conceptual Architecture Kernel core functionality reused in all EGS-CC based systems application support with fully generic functionality M&C kernel, with generic monitoring and control functionality reused in all projects without modifications, but can be extended Reference Implementation components forming complete EGSE/MCS systems which use the EGS-CC kernel any component replaceable by user‘s own implementation e.g. PUS S/C M&C, ground equipment M&C, user applications Reference Test Facilities external elements required for full validation of Kernel and RIs, i.e. of EGS-CC itself and systems built using EGS-CC e.g. S/C emulation, ground support equipment emulation,... www.DLR.de Chart 7> CCSDS SM&C WG > Stefan Gärtner EGS-CC Overview > 2016-04-05

13. Conceptual Data Model provides commonly shared definitions of all the exchanged data defines full context of data that is handled by the MCM ensures integration with the full system engineering process performed during spacecraft AIT and finally also during mission defined in UML to allow model-driven engineering approach actual technology for data exchange not reflected in CDM can be mapped to external models, e.g. SCOS 2000 MIB www.DLR.de Chart 13> CCSDS SM&C WG > Stefan Gärtner EGS-CC Overview > 2016-04-05

14. Monitoring and Control Model static MCM aka MCM Definitions M&C data produced during development and maintenance of Space System used to tailor EGS-CC for a given mission based on M&C perspective of ECSS Space System Model dynamic MCM aka MCM State M&C data produced by Space System during testing and operations held transiently during processing archived for retrieval and analysis www.DLR.de Chart 14> CCSDS SM&C WG > Stefan Gärtner EGS-CC Overview > 2016-04-05

15. Monitoring and Control Model ensures separation between abstract M&C view/generic processing and specific processing/concrete exchanged data units hierarchy of M&C Elements – activity, event, reporting data Kernel based on abstraction provided by MCM (and includes MCM) supports generic M&C no dependencies on specific equipment, protocols, data structures www.DLR.de Chart 15> CCSDS SM&C WG > Stefan Gärtner EGS-CC Overview > 2016-04-05 Monitoring and Control Layer Service Layer Packetization Layer which task by means of in which structure

17. ISIS Convergence convergence study to assess EGS-CC interoperability with CNES ISIS several convergence proposals identified, one of them: implementation of EGS-CC MO adaptation component compatible with ISIS transport and encoding layer by mutually exclusive solutions: reuse of ISIS communication components reuse of ISIS communication library design choices development of reference MO Library EGS-CC always provider of MO, never consumer however, MO Library supports both roles www.DLR.de Chart 17> CCSDS SM&C WG > Stefan Gärtner EGS-CC Overview > 2016-04-05 ISIS: MO drives service-oriented architecture of ISIS EGS-CC: MO is interoperability facility, provided through adaptation component EGS-CC: MO is interoperability facility, provided through adaptation component
