SOIS-APP Working Group Report Jonathan Wilmot (WG Chair) Richard Melvin (WG Deputy Chair) 1 1 1

SOIS-APP Executive Summary Goals for this meeting cycle: Discuss and document updated SOIS architecture and SEDS use cases Determine the interoperable interfaces at each architectural layer Align updated SOIS architecture with SEA, MOIMS concepts Discuss relationships and/or architectural overlaps with SEA and MOIMS WGs Discuss and disposition SEDS and DoT book RIDs Discuss results of ESA study to autogenerate data acquisition flight software solely on SEDS definition of devices Discuss results of NASA effort to integrate SEDS in the cFS software framework Discuss results of NASA effort to generate operations XTCE database from SEDS Discuss results of CAST implementation of SOIS architecture Working Group Status: Accomplished all stated goals of meeting (listed above) Determined there are overlapping areas with MOIMS MO services All RIDs and Github issues discussed and dispositioned JAXA is interested, resources being identified. Possible issues getting resources allocated / schedule.

SOIS-APP Executive Summary Working Group Status (continued): Decision to Silver existing app books: 871.1-M-1, 871.2-M-1 , 871.3-M-1, 872.0-M-1, 873.0-M-1, 875.0-M-1, 871.0-M-1 and move conceptual primitives to SOIS 850.0-G-2 Reviewed draft of CAST Flight Software as a CCSDS Onboard Reference Architecture Problems and Issues: Very limited funding for contractor support in FY17 (Ramon Krosley is book author) NASA projects waiting book updates Planning: Richard will review the MAL for SEDS overlap/translatability (funding TBR) Update and reissue 850.0-G-2 (will include some of the user’s guide content) Update XML Specification for Electronic Data Sheets BB ESA primes to study EDS (starts second half 2017) NASA and CAST SEDS prototyping in work Complete and submit Electronic Data Sheets and Common Dictionary of Terms - Overview (870.1-G) and include user’s guide content Delete Spacecraft Onboard Interfaces Services User’s Guide project Interaction with other WGs: Joint meeting with SEA and MOIMS working groups SOIS representative participation in SEA WG JAXA is interested, resources being identified. Possible issues getting resources allocated / schedule.
