Plastow NASA Customer: SCaN Program/John Rush Key Contractor(s): GESS/ASRC; SpaceDOC/ZIN Project Mission Statement: Develop, deploy and operate a communications, navigation, and networking testbed on ISS to advance the TRL of Software Defined Radios (SDR) and the Space Telecommunications Radio Standard (STRS) in support of future NASA missions. GRC Scope: The SCaN Testbed project is defined as the design, build, launch, and operations of the SCAN Testbed, as well as the development, integration and on-orbit execution of experiments and other users. Project closeout will occur no earlier than 2018, or upon Program direction, with SCAN Testbed decommissioning, disposal, and final documentation. GRC will lead a multi-partner team (GSFC, JPL, JSC, General Dynamics and Harris) to deliver the testbed for launch on JAXA’s HTV3 in July 2012 and operate for a minimum of 3 years.

14. 14 SBIR 2011 Phase I Experiment Formulation/Concept Development in FY12 #7, Radio Navigation Waveform (Codeless GPS), Emergent – Developing concept of operations for spectral compression positioning technique – Developing performance analysis for spectral compression positioning technique at SCaN Testbed location onboard ISS, based on payload location on ELC-3 #8, Agile Cognitive (Signal detection) – Space Micro – Updating objectives wrt SN LGA antenna placement and HW operational parameters – Gathered detailed documentation of the JPL SDR to develop a good understanding of the system operation as well as the interface points for the waveform (ASR) firmware. Identified firmware connection points that allows transfer of analog RF data into VHDL digital domain for process in as well as the VHDL control points allowing VHDL control of the JPL SDR hardware. The ASR experiment intends to process the entire USB uplink band at one time, channelize the observed signals, categorize and report the finds. #9, Scintillation Hardened GPS (Solar Flare Study) – Comm Largo – Developed a MATLAB tracking simulation that allows selectable evaluation of a Kalman filter and a conventional PLL filter as a phase detector for GPS signals undergoing scintillation. The scintillation is produced according to the Cornell Scintillation Model. – Performed testing using the GNSS SDR receiver waveform on the Ettus Research USRP-N210 SDR. The current design allows a selectable interface of either signal samples or a live RF receiver. – Started preliminary design of the Eclipse-based plugin for developing STRS-compliant waveforms.

Issues and Concerns HRDL Repair Timeline –After the initial ~7 days of checkout that the SCAN team can get through without HRDL, schedule will slip day for day Without the HRDL, the SCAN team will not have the necessary telemetry to continue on with checking out the S-band and Ka-band experiment functions Not a safety concern since safety telemetry via ISS 1553 path; no Hazard Report change –Crew Time allocation may not enable HRDL jumper cable installation until after HTV3 undocking (~30 days) De-couple SCaN Testbed impacts from CoFR approval to avoid unnecessary confusion Continue to work with ISS to accommodate repair within overall crew activity prioritization 17

21. RankRisk IDRisk StatementApproach & PlanComments 11 SCAN-135Underfunded Operations and Experiments Phase Given the: limited funding available for Phase E of the SCaN Testbed Project, There is a possibility that: Level 1 requirements may not be met. Context: Per PPBE-14, the SCaN Testbed budget is limited during FY13 - 15, and is zeroed out in FY16 and beyond. The ability to fund new experiments and complete the Software Development as identified in the SW Requirements Specification, is significantly constrained. This may result in the deferral of many experiments' completion until late 2014 and 2015, deferral or elimination of Priority 2 and Priority 3 SW requirements, and deferral or delay of the SW Code Optimization tasks that were planned to increase the CPU margin available to experimenters. If the SCaN Testbed is decommissioned in 2015, it is possible some Level 1 requirements may not be met. Mitigate 1.Release NASA Research Announcement (NRA) to attract experiments that do not require SCaN Program funding, by 6/30/12. 2.Assess Level 1 impacts given current software funding and experiment funding. Present as part of the ORR briefing packages, by 6/5/12. 3.Prioritize remaining software development to maximize capability using Level 1 impact assessment, by 6/30/12. 4.Develop PPBE-15 request to SCaN Program to support more robust utilization of SCaN Testbed, by 3/31/13. 5.Seek non-SCaN Program funding via pursuit of other NASA sponsors, such as OCT, for internal experiment development, by 6/30/13. STATUS: PPBE-14 budget cycle activities and decisions during March-April 2012 have established a minimum set of requirements for viable implementation in FY13. Significant work has been invested in the planning and formulation of a NRA (formerly known as Announcement of Opportunity) to be released in June 2012 to attract non-SCaN Program sponsored use of the SCaN Testbed. ORR and KDP-E briefing packages to address software status and include PI assessment. ORR scheduled for June 2012, and KDP-E to occur shortly thereafter.

22. RankRisk IDRisk StatementApproach & PlanComments 22 SCAN-123Experimenter Software Interface Given the: software interface between avionics software and experimenter software on the avionics is in development, There is a possibility that: experiment software will be difficult to integrate with the PAS. Context: Experimenters are expected to provide software applications to run on the avionics. The first planned software is the baseline IPv4 networking experiment. Mitigate 1.Reduce initial functionality by only implementing the portions needed for baseline networking. (completed 9/30/11) 2.Implement software capability for initial networking experiment. (completed 9/30/11) 3.Defer testing/verification of baseline networking from Flight System, pre-ship to GIU, post-ship. (completed 4/27/12) 4.Decompose requirements that describe standard experimenter software interface capabilities, by 6/30/12. 5.Implement software interface capabilities in post- ship version of PAS software on-orbit with experimenter interfaces, by 12/31/12. STATUS: After the Flight System has shipped, testing on GIU has been completed and has verified required kernel capabilities are sufficient. Determined further requirements decomposition is necessary to appropriately implement experimenter interface capabilities.

23. RankRisk IDRisk StatementApproach & PlanComments 33 SCAN-136Loss of Experienced Software Personnel Given the: loss of several SW engineers that have left GRC, There is a possibility that: on-orbit troubleshooting will be inefficient. Context: Several SW engineers have left the project, and several have left GRC. The SW personnel still at GRC but redeployed to other projects will be tasked with troubleshooting if required, however the ones that have left GRC are not available at all. Mitigate 1.Reassess and reassign responsibilities for existing software code to remaining software team, by 6/15/12. STATUS: Re-prioritization of work is underway with remaining team member skills and scheduled deliverables in preparation for Phase E.

Context: The ELC HRDL jumper cable is scheduled for launch on HTV-3 and on-orbit installation and checkout is planned for shortly thereafter. Mitigate 1.Request that ISS schedule HRDL repair prior to SCaN Testbed installation on ELC- 3. (completed 3/30/12) 2.In coordination with ISS, verify HRDL functions during Checkout and Commissioning, by 9/15/12.
