SOIS Area Report - SOIS Area Report - Current Groups within Area
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

Application Support Services Working Group
Goal: Develop SOIS Application support layer services and if appropriate protocols
Working Group Summary progress:
• File & Packet Store Services Magenta Book RIDs handling in progress
• Device Data Pooling and Message Transfer Services ready for publishing
• Device Access Service ready for publishing
• Device Virtualisation and Device Enumeration Services undergoing final updates before CESG poll for Agency review
• Green Book Issue 2 under finalisation
• Agreement on consolidated architecture for standardising functional interfaces to onboard devices
Working Group Summary Situation:
Status: OK CAUTION PROBLEM
Comment: Finalizing number of books

Application Support Services WG (cont.)Primary Objectives for the fall meeting:
• Completion of SOIS Green Book Issue 2 & architecture for Device Virtualisation• Finalising FPSS, MTS, DAS, DVS Magenta Books• Define approach for defining Generic Device Functional Interfaces as part of the
DVS and DAS services
Progress• Excellent support this week and agreement on a consolidated SOIS architecture
compatible with, SAVOIR, GSFC CFE, and SPA • Agreed to define a set of common interfaces per class of onboard (AOCS) devices that
hide detailed interfaces from application software• Will be defined with the support of machine readable electronic data sheets that can be
directly used by flight software for configuration purposes• SPA Xteds will be used as starting point but will results will be published as CCSDS
recommendations with the support of SANA• Basic work plan formulated with significant support committed by GSFC and AFRL
Comment: The concept and usefulness of SOIS is finally being appreciated!

Wireless WG
Goal: Develop wireless recommendations for 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…).

Wireless WG
• 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
• Progress
• Emerging needs for high data-rate wireless communications indentified. 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

SOIS Area Report - SOIS Area Report - Summary Technical Status
Wireless WG (cont.)
• 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
cesg-10June 2010
SOIS APP and MOIMs SM&C
• Joint presentation provided on architectural aspects
• No overlap issues identified as MO is not defining flight applications, rather it provides a framework in which they can be implemented
• Flight applications will interface with SOIS and this is where further liaison may be necessary in the future
SOIS Area Report - SOIS Area Report - Cross Area Meetings
cesg-11June 2010
• Approve Message Transfer, DDP, DAS magenta books for publication
• Approve publication of SOIS Green book v2
• Approve Agency review for DVS and DES Magenta books
• Approve updated charters and work plans for both working groups
• Approve Publication of Wireless low rate sensor network magenta book
