1. Nov11-cesg-1 SOIS Area Report Wireless WG Primary Objectives for the fall meeting Establish lessons learned from the Asset Management (AM) Magenta Book submission Modify the Low Data Rate (LDR) Magenta Book’ structure to reflect the comments received and accepted for the AM MB, the major item being the establishment of a clear distinction between normative and informative material. Investigate the requirements and need for high data-rate applications Review and update the next-years roadmap for the Wireless Working Group Secondary Objectives for the fall meeting Further define the technical architecture and the cooperation and administrative framework of the shared test bench for smart sensors (SSIART) Review the status of the joint Wireless for space symposium 2012

2. Nov11-cesg-2 status:OKCAUTIONPROBLEM comment: Very Good SOIS Area Report Wireless WG Working Group Status RFID-Based Inventory Management Systems Magenta Book approved by CESG and now under CMC review. Low data-rate wireless communications for spacecraft monitoring and control Magenta book (LDR MB) is completed but needs to have a security section in annex (completion foreseen end-of-November). The WG has identified emerging needs for high data-rate wireless communications. We will investigate and consolidate the identified use-cases and requirements before the next meeting and will then assess the need for standardization. – See next slide. The WG has also identified that providing guidance in the testing and coexistence activities associated to wireless communications in space applications might help the Industry mitigate the related challenges. The WWG will draft test procedures and will evaluate if such guidance belongs in the GB or the LDR MB before the next meeting. – See next slide. Discussions took place about the technical programme of the joint symposium on wireless technologies to be held in North America in September 2012. The SSIART activity is moving forward and an administrative agreement between ESA and NASA is currently under way (Export & IPC…). ESA and NASA are currently defining the technical objectives and specifications of the activity. Working Group Summary Situation:

3. Nov11-cesg-3 SOIS Area Report Wireless WG More details about the emerging needs for high data-rate wireless comms CCSDS Low Data-Rate Magenta Book supports applications with up to ~100 kbps shared bandwidth Many real-time waveform capture applications require ~10 Mbps per instrument channel: high-frequency vibration monitoring micrometeoroid impact detection leak location estimation electrocardiogram (ECG) crew health monitoring HD video applications require ~10 Mbps per flow: video-enhanced situational awareness public outreach Interoperability statement: The deployment of high data rate wireless solutions for AIT and DFI is a clear and short term need expressed by the users community and especially industrials. This would for example enable implementing a wireless access point on the equipment, or on the spacecraft data buses, allowing non intrusive data collection and analysis, speeding up the integration. Such deployment has no chance of success if interoperability is not supported; especially as the majority of flight equipment undergoes several testing and integration phases at different locations, and at different agencies for a number of programs. In a shared environment (e.g. ISS, test center, habitat…) with an integrated wireless data bus (chipsets built by different suppliers), interoperability is required. Based on these agency-identified needs, the WWG will identify and consolidate the use-cases and requirements for high data-rate wireless applications to address applications requiring ~10-100 Mbps data flow.

4. Nov11-cesg-4 SOIS Area Report Wireless WG More details about the testing procedures and specifications for ground and onboard Wireless Systems Based on the challenges raised by evaluating and comparing numerous different wireless technologies, the Wireless Working Group (WWG) believes that a level of guidance is required to assist system engineers in the adoption, integration and testing of wireless solutions in space systems. For example: If wireless subsystems share the same bandwidth in a vehicle, how does one determine the impact of coexistence on the performance of the individual subsystems (latency, data rate, power consumption, expected lifetime, etc.)? Are there rules of thumb, guidelines, etc.? If a wireless subsystem is deployed in a particular environment, how does one determine the impact of the environment (propagation characteristics, RFI characteristics, etc.) on the performance of the individual subsystem? Rules of thumb? Guidelines? In general, what are the considerations that must be evaluated when introducing wireless subsystems into a vehicle or environment, and what are the test procedures for evaluating such considerations? Rules of thumb? Guidelines?
