SOIS Area Report - Current Working Groups
Application Support Services WG
Wireless WG
Subnetwork Services WG (Inactive)
The SOIS area covers onboard communication services with the intention of standardising H/W and S/W interfaces between avionics elements & devices.
Wireless activities cover intra-spacecraft communication, AIV and RFID
A considerable part of our work is outside of the CCSDS where we perform a harmonising role for avionics related development 2 2 2

5. SOIS Area Report Application Support Services WG (cont.) Progress
All 1st set of SOIS APP service specifications are either published or with Secretariat for publishing or for Agency review process
The specifications are compatible with several existing architectures (ESA, NASA, AFRL)
After WG analysis the use of electronic data sheets and associated schema to define device interfaces, has been assessed as providing great benefits not just within SOIS but in a much wider context (data driven interfaces, spacecraft data base import, auto testing etc).
Rationalised how functional interface information will flow through mission and spacecraft development process, how to represent these different uses (“onion diagram”) and how EDS structure will cope with this breadth of usage.
Initial focus will be on EDS for onboard devices & for onboard software bus components
Defining standard functional interfaces remains out of scope of SOIS as this is better left to external groups
Explored how SUMO, NASA-JSC and NASA-GRC can contribute to this process, e.g. US industry outreach, example real-world ICD transformations to EDS
Planning
Publish remaining Green and Magenta Books
Continue fortnightly telecons
Produce first cut EDS XML Schema for Spring 2013 meeting
Extend Common DoT taxonomy with common terms for examined ICDs for Spring 2013 meeting
Consolidate interface with SUMO group (if any) – meetings planned for next week 5 5 5

Progress
Several use cases identified which require high-speed wireless connectivity (ISS comms and multimedia support, ESA standard telcom platform AIT) - in general data transfer requirements increasing for all existing use cases
Planning for symposium on wireless technologies to be held in North America in September 2012
Planning
Update Green book to cover High rate use cases and technology evaluation
Development of magenta book covering high-rate wireless technology (on completion of green book)
Continue with the definition and usage of the SSIART

Comment:
The SOIS area has solid funding for this year and intentions are good for the future. ESA has a tight travel budget and this is unlikely to change. Fortunately, we are well supported by independent Agency activities and this allows significant work to progress between CCSDS meetings. 10 10 10
