07-Apr-2014-cesg-9 Wireless WG Goal : Develop wireless recommendations for onboard space applications Working Group Progress : The Green Book update to integrate high-speed wireless communication technologies and use-cases has faced image copyright issues; these were resolved during the meeting and an updated GB version (with copyright information) will be provided again to the CCSDS editor after the technical meeting. The work on the “RFID Tag Encoding Blue Book”, with a lead from NASA & FSA and with ESA & CSA as participants, has been started in Spring and the first draft version has been completed and internally reviewed at this meeting. This reviewed draft will be reviewed by Agency stakeholders (e.g. Mission Integration and Operations Office, FSA, ESA), where the feedback will be incorporated into a second draft which will then be reviewed by the WG before being released to AD. Planning for the development of the “Wireless Local Area Network Blue Book”, with a lead from NASA & FSA and with ESA & CSA as participants, has started. The schedule for the production of this book has been updated to reflect the recent official acceptance by both NASA and FSA, and actual start date (Spring 2015) The SSIART (Smart-Sensor Inter-Agency Reference Testbench ) MOU has finally been signed by all parties Proposal to form a BoF to investigate the need for standardization in the area of Time triggered networks including the interfacing and bridging to Wireless SOIS Area Report

07-Apr-2014-cesg-11 Proposal for new BOF Current human rated vehicles e.g. the ISS use a relatively ad-hoc mix of Time triggered (Milbus), wired asynchronous (Ethernet) and Wireless (802.11) communications technologies to support a variety of applications: Command and control, Science date, Audio and Video, Crew health monitoring, Robotic control Such a mix of services serves to indicate the types of applications that now need to be supported and will required in future exploration missions. There is a clear trend to support these services by use of a single bus able to handle multiple traffic types at high rate. This reduces the number of interfaces necessary for each end-item. Several emerging technologies look promising and able to fulfill a mix of synchronous and asynchronous traffic including Time-Triggered Ethernet (TTE), Time-Triggered Protocol (TTP) and SpaceFibre (SpF). Wireless technology providing all capabilities is in its infancy but seamless communication between wired and wireless networks is highly desirable. The wireless group has proposed a BOF to evaluate these new technologies with a view to standardising their use in space

SOIS response to CMC Appl. Support WGs has no activities identified as part of FP beyond Is it anticipated that all goals will then be achieved and the group has no further activity ? – SOIS has been careful to obtain resources before pushing forwards with new work items and this may give a false impression to the CMC on what is planned – If required we can list a series of extensions and future work to take us way beyond the present near term vision – As a heads up we can state that the SOIS services must evolve in response to implementation feedback and development of electronic data sheets will take many years to mature and for the full potential to be realised – Example work items: Synchronous service interfaces Data Streaming services Mapping to new subnets Simplified MTS protocol Network management 5 year review

The SOIS Area has only one WG (Wireless) and no activities identified as part of FP beyond Is it anticipated that all goals will then be achieved and the group has no further activity ? – The RFID encoding Blue book should be finalised in 2016 but the WLAN will not be completed before 2020 – A new SIG has been proposed to evaluate the use of deterministic networks required for future exploration missions, this is likely to lead to significant new work Should the group be disbanded earlier and the WG activities be re-allocated to another area (Wireless  SLS?)? – The rational behind this question is not understood as it could also be applied to other groups – There seems to be no technical reason to do this? – the SLS area is anyway overloaded, and it may be more appropriate to move any relevant SLS groups to SOIS and thus even the load on the SLS area director SOIS response to CMC

More globally, only short term ( ) workplan defined. Is this area required beyond 2015? Should CCSDS maintain a role in onboard interface standards? – The updated work plan take us well beyond 2020, so yes we need this area after 2015 – The CCSDS has undertaken this area of activity and we now have many users and implementations, it is therefore incumbent on CCSDS to maintain these standards and evolve them according to Industry and Agency feedback SOIS response to CMC

Future developments for onboard “Standard Avionics Architectures” were mentioned in the 2014 CMC spring meeting (SUMO). Is this a viable direction; should CCSDS get involved in standardising onboard architectures? – A “STANDARD Avionics architecture” is not foreseen by SOIS but a ‘REFERENCE communications architecture’ was developed to locate the SOIS services and then apply the electronic data sheets – Within the CCSDS we need a “Reference architecture” which is able to locate ALL CCSDS books and this will need to cover ground, the space-link and the onboard system (This is anyway a CMC request) SOIS response to CMC
