MOIMS MO & Nav Functions, Services & Interfaces CCSDS Ref Arch Discussion 20 Oct 2015

Approach Use provided MO services (Nestor) & Nav service (Nav WG) diagrams Edit them minimally for clarity and consistency so traceability is clear – For now the diagrams remain in their original, and inconsistent, styles Show how they relate to each other and to CSS services Attempt to clarify and discriminate among: – Data structures and formats – Functions (and groupings) – Service interfaces

Notes on Revised MOC with MO Services diagram Provides view of the MO, FDS, & CSS interactions, showing major interfaces (“grey boxes” show groups of functions, exchanged data structures are shown as green boxes) All data transfers are shown as data, not as “services”; data exchange structures and formats must be standardized for interoperability Service Interfaces are explicitly shown associated with the functions that provide them Five MOIMS Service groups shown: Navigation (FDS), Monitor & Control (M&C), Automation, Planning & Scheduling (P&S), MO Data Services Data archiving, auditing, and Robotics etc are not shown for now CSS Services (SM, CSTS, SLE) are shown explicitly as service providers Not all of the service requests nor data flows to/from the SOC / PI are shown (mission planning & automation requests, commands, science data, archival data, etc, etc) FDS to MO interactions are shown on a separate Nav WG chart (with edits) NOTE: most of the service interfaces could continue to be mission specific (as now), or converted to an MO Service framework, or just use TGFT- like services, or …

Notes on Revised Flight Dynamics (FDS) Services diagram Provides view of the separate FDS to MO interactions, showing major interfaces (“circles” are functions, types of data structures are named on connectors) All data transfers are shown as data, not as “services”; data exchange formats must be standardized for interoperability Service Interfaces are explicitly shown associated with the functions that provide them, but they may not offer explicit service interfaces Navigation (FDS) services are shown, using the functions and data structure standards defined in the Nav WG diagram (Richon v 4.2) CSS Services (SM, CSTS, SLE) are shown explicitly as service providers All of the elements are re-named, where needed, to produce a consistent functional view; teams and processes are separately indicated NOTE: most of the service interfaces could continue to be mission specific (as now), or converted to an MO Service framework, or just use TGFT- like services (as shown)
