Apr12-cesg-2 1. Application Support Services WG 2. Wireless WG 3. Subnetwork Services WG (current work completed) SOIS Area Report - Current Working Groups The SOIS area covers onboard communication services with the intention of standardising H/W and S/W interfaces between avionics elements & devices A considerable part of our work is outside of the CCSDS where we perform a harmonising role for avionics related development

Apr12-cesg-6 Application Support Services WG (cont.) Progress (cont.) Clarified books to be produced for Electronic Data Sheets and plan agreed: Electronic Data Sheets for Onboard Devices Blue book Electronically describes: Device-specific Access Protocol, how to access a device using subnetwork services Functional Interface, how to access the functions provided by the device, virtualised from the access method. For example, using engineering units rather than raw values Device Abstraction Control Procedure, mapping on the Functional Interface on to the Device-specific Access Protocol Ancillary Information, text, figures etc. Book describes structure and required elements within an Electronic Data Sheet Electronic Data Sheets XML Schema XML Schema to use for creating a device’s EDS in XML Pulls in Common DoT XML Schema Held by SANA Common Dictionary of Terms for Onboard Devices Blue book Common syntactic and semantic types used in device EDS Common Dictionary of Terms XML Schema XML Schema to use for creating Common DoT in XML Held by SANA SOIS Area Report

Apr12-cesg-9 status:OKCAUTIONPROBLEM comment: Very Good Wireless WG Goal: Develop wireless recommendations for onboard space applications Working Group Summary Progress: RFID-Based Inventory Management Systems Magenta Book in publication Low data-rate wireless communications for spacecraft monitoring and control Magenta book (LDR MB) under completion The SSIART (join test-bed) activity is moving forward and an administrative agreement between ESA and NASA is currently under way (Export & IPC…). SOIS Area Report Primary Objectives for the fall meeting Digest lessons learned from the Asset Management (AM) recommendation Finalize Low Data Rate (LDR) Magenta Book Refine technical architecture and the cooperation and administrative framework of the shared test bench for smart sensors (SSIART) Review and update the next-years roadmap Review the status of the joint Wireless for space symposium 2012 To be updated

Apr12-cesg-10 Wireless WG Progress Emerging needs for high data-rate wireless communications identified. Will be further investigated with consolidate the use-cases Identified the need for additional guidance for the testing and coexistence activities associated with the introduction of wireless communications Technical programme of the joint symposium on wireless technologies proposed to be held in North America in September 2012 Future Work Publish Low Data Rate (LDR) Magenta Book Consolidate proposal for work plan on high rate wireless transmission Conclude on the need for additional guidance to users on the application of wireless technology and propose work plan accordingly Continue with the definition and usage of the SSIART Continue fortnightly telecons SOIS Area Report To be updated
