  1. SPACECRAFT ONBOARD INTERFACES SERVICES (SOIS) AREA Chris Taylor (AD) Stuart Fowell (DAD)

  2. SOIS Area Report B. Meeting Demographics

  3. 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

  4. SOIS Area Report • Application Support Services Working Group • Goal: Develop SOIS Application support layer services and if appropriate protocols • Working Group Status • Green Book Issue 2 ready for sending to Secretariat for CESG Poll to publish • File & Packet Store Services Magenta Book CESG Poll RIDs dispositions agreed & updated book with Secretariat for publishing • Device Data Pooling & Message Transfer Services Magenta Books CESG Poll RIDs dispositioned • Device Access Service Red Book ready for sending to Secretariat for conversion to Magenta Book at CESG Poll to publish • Device Virtualisation & Device Enumeration Services Red Books ready for sending to Secretariat for 1st Agency Review • Finalised plan for Electronic Data Sheet for Onboard Devices Blue Book & associated XML Schema • Finalised plan for Common Dictionary of Terms for Onboard Devices Blue Book & associated XML Schema

  5. SOIS Area Report • Application Support Services WG (cont.) • Progress • All SOIS service specifications are either published or in 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) • The intention to define standard functional interfaces within the SOIS has been de-scoped as this is better left to external groups • Planning • Publish remaining Green and Magenta Books • Issue new CWE projects for Electronic Data Sheets & Common dictionary or terms • Continue fortnightly telecons

  6. SOIS Area Report Application Support Services WG Near Term Planning

  7. Wireless WG SOIS Area Report • Goal: Develop wireless recommendations for onboard space applications • Working Group Status: • RFID-Based Inventory Management Systems Magenta Book Published • Low data-rate wireless communications for spacecraft monitoring and control Magenta book ready to submit to CEGS for Agency review • The SSIART (joint test-bench) MOU under signature process • 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 • Continue with the definition and usage of the SSIART • Continue fortnightly telecons

  8. SOIS Area Report Wireless WG (continued) Near Term Planning

  9. Cross Area Meetings: SOIS APP and MOIMS SM&C SOIS presentation on use of Electronic Data Sheets in spacecraft development process Definition of interface to devices (send/receive), not device functionality Discussion on where data from Electronic Data Sheets are used, e.g. spacecraft database, device simulators, TM/TC databases Exploration as to what structures XTCE & MO Services MAL have that are of benefit for use in Electronic Data Sheets SOIS Area Report

  10. SOIS WGs Telecon Usage

  11. ASWG DDPS and MTS CESG rid updates prior to publication FPSS under publication DAS under publication Green Book Issue 2 under publication DVS, DES ready for agency review Electronic data sheets work initiated Wireless WG RFID Magenta under publication Low rate wireless Magenta book ready for Agency review export and ITAR clearance for test-bed cooperation under signature Green book issue 2 under development Comment: The SOIS area has sufficient funding for this year and intentions are good for the future. Fortunately, we are supported by independent Agency activities which allows the CCSDS work to proceed with minimum effort. SOIS Area Report: Summary
