February Monthly Status Review (MSR) Note: No presentation this month SCaN Testbed David Irimies, Project Manager March 14, 2013

Issues and Concerns Top Project Risk #1 Key Issue/Concern Potential / Realized Impact Action Plan Resolution Date Out-Year Funding Profile Insufficient to Execute Project Given an out-years (FY14+) resource shortage, there is a possibility that: STB Expt integration and operations will idle/intermittently stop – with average of 1-2 weeks per month of on-orbit ops capability, with remainder of month for ground verifications, mission planning, etc. -will further hamper mitigation of Top Project Risk #2 (External Experimenter Support) STB Leadership to meet face-to-face with SCaN Program on working FY14 budget mark, discuss impacts, and request partial reprogramming of funds from supporting Center to GRC. Assemble FY14 budget and prioritized content/experiments, including overguide/deferred content, and present to Program, and respond to PPBE/PRG guidelines/marks. Request SCaN Program reserve / additional funding beyond existing mark; pursue external-to SCaN funds e.g. ISS Program Complete 2. Complete Continual 2

Issues and Concerns Top Project Risk #2 Key Issue/Concern Potential / Realized Impact Action Plan Resolution Date Funding Insufficient to Fully Support Experimenter Requests of STB Capabilities Given a resource shortage to fully support experimenter requests, there is a possibility that: STB unable to timely accommodate external Experimenters Increased development time and effort for all Experimenters Example: EDS delivery and RF HID – 1 year slips Include External Experimenter requests - approved by project - as part of PPBE package (Action Plan Item #2 in “Out-years funding…” risk) Continue to Prioritize new SW capabilities based upon experimenters in the queue, impact to Level 1 Requirements and STB Mission Success Criteria, and SCaN Program priorities Continue to adopt a “Level of Effort” approach for experiment integration and SW modifications 4. Continue to evolve and streamline experiment integration processes Complete Continual 4. Continual 3

Stoplight Status and Explanations CURRENT MONTH EXPLANATIONS Rev 3/14/13 Cost Schedule Technical Mgmt Current Month G R Y Prior Month CURRENT MONTH EXPLANATIONS Sched Issue / Impact Issue / Impact (ctd) Action Plan R Schedule slips due to Resource Shortages, and External Factors Completion of Commissioning (Comm’n) and Antenna Characterization has slipped to >2 months beyond baseline schedule (ref 10/16/12), due to: 1.) Resource and Workforce Shortages– activities complete faster if more resources and staffing of those resources (including Mission Ops, and experiments for SDR characterization). Also, intermittent pauses in on-orbit testing due to being one deep staff in most areas. 2.) Scope and Success Criteria of Checkout/Commissioning – bar too high 3.) TDRS Power Level Changes – during Rnd 1 of Antenna Characterization 4.) TDRS HIJ autotrack debugging (first unofficial experiment) – delayed APS Commissioning for 3 weeks 5.) Critical Commanding Issue - had shut down STB over 2 weeks 6.) ISS inhibits and SN/NEN scheduling continue to challenge planning – over 4 weeks Continue to request filling workforce/staffing gaps via STB Position Description document. Revise Comm’n Success Criteria Existing staff barely able to process procedures, verifications, etc. within single experiment (waterfall) – EX – pushed out completing procedure development and GIU dry runs of procedures from early/mid Dec to mid to end Jan. (2+ weeks b/c insuffic. BW in 7.0 WBS to develop/review procedures while in parallel executing Checkout) Idled the SCaN Testbed on orbit for >2 weeks, delayed completion of Checkout/Commissioning past baselined date of Dec. 31 Further delayed Commissioning for 2 weeks: Mission Ops staff can’t fully support Comm’n planning during console ops for Checkout Negatively impacting progress of experiments. 3a. Delayed completion of first 2 experiments (S-band and Ka-band technology) 3b. Delayed delivery of GRC in-house experiment currently in development (Expt 6 - Hi Rate BW-Effic. Ka-band WF) 3c. Descoped GRC in-house experiment in development (Expt 15 – Cognitive) 3d. Downstream: existing staff can’t fully process multiple experiments at the same time Seeking Code D/R CS lead roles Restore full-time support of existing comm. personnel Waveform SW & FW (Complex Elect) devel.

CMC Stoplight Variance Criteria Cost G Project is less than 5% variance from plan (+ or -) or under $500K; Y Project is greater than 5%, but less than 10% variance from plan (+ or -) and over $500K; R Project is greater than 10% variance from plan (+ or -), and over $1 Million. Schedule Project is less than 1 month variance from plan; Project is less than 2 months variance from plan; Project is greater than 2 months variance from plan. Technical G Major requirements are being met by the current design; Y Major requirements are not being met, but feasible options have been identified and accepted (directed and funded) that will meet all requirements; R Major requirements are not being met and options for corrective action are not yet shown to be feasible and/or are not yet directed and funded. Management Project implementation is not hampered by lack of resources, including budget, workforce, facilities, contracts, project management tools and documentation (requirements, plans, procedures, etc.); Project implementation is limited by the lack of one or more resources, but corrective action has been identified and approved; Project implementation is impacted by the lack of one or more resources, with corrective action not yet identified and/or approved. Costing actuals <1% over phasing plan *NEN-LGA – investigations ongoing *SFEP/EFEP – resolutions in testing See CMC Chart Corrective action identified, and partially implemented

Content for BPR submission The SCaN Testbed (STB) successfully completed first round of Software Defined Radio (SDR) Commissioning Narrative: SCaN Testbed completed its first round of Software Defined Radio (SDR) Commissioning. SDR Commissioning verifies the end-to-end data flow of the SCAN Testbed and ground systems; and, SDR Commissioning verifies that the radio link performance is predictable. Success is a high bar, with error free performance on the forward and return links. The STB team executed 42 events over 11 straight days, with 9 of 27 total tests fully complete and closed (many tests required 2 passed events per test, another high bar). The STB team performed extremely well, with excellent integration of White Sands Complex and STB personnel. The STB team is on track to better understanding the system issues and predicting the SDRs’ performance.
