In work. 1b.Assign Bryan Welch to SCaN Testbed full time until new RF SME is identified to cover RF Checkout, Antenna Characterization, APS and SDR Commissioning (Sep’12– Jan’13). Done. 1c. Seeking support from Code D/R. Done. Obtained supporting role from Code RHE, but still need full-time RF SME. 2. Accept smaller GRC experiment portfolio and deploy resources to securing, integrating and operating outside experiments 1. Dec 2012?

6 Remaining Checkout & Commissioning Activities  RF Checkout: 10 days (2 completed) 1.Antenna Characterization: 15 days (was supposed to start Sep 24) Antenna Characterization procedure development and planning in preparation for on-orbit ops the week of 10/22 2.JPL Commissioning: 5 days Experimenter submitited test matrix 3.GD Commissioning: 5 days Experimenter working test matrix 4.APS Commissioning: 15 days 5.Harris Commissioning: 5 days Experimenter working test matrix Timely completion of Commissioning hinges on development and submission of scripts / test matrices – Required ~6 weeks prior to date of execution T-5w: Develop procedures T-4w: Dry runs on GIU T-3w: Mission Ops to request ISS, SN, and NEN services. 6

7 Experiments 1 and 2 (S- and Ka-band SDR Technology Advancement) – Performing characterization of GIU engineering model SDRs to allow on-orbit performance predictions for new waveforms – Developing JPL SDR waveform enhancements on GIU for upload to flight Signal-to-noise ratio estimator Received power estimator – Developing experiment plans to prepare for upcoming on-orbit operations Experiment 3 (Baseline Networking & Routing) – Working experiment plan and detailed execution/development schedule. – Developing ground interfaces for bidirectional data transfer to SCAN TB. Experiment 6 (Bandwidth Efficient, High-Rate WF at Ka-Band) – Creating an experiment plan to address future development and operations – Placing procurements for software development environment Experiments 7, 8, 9 (SBIR Phase 1 – complete August 2012) – Evaluating SBIRs for potential phase 2 awards; the SBIR portfolio includes work in codeless GPS, scintillation-hardened GPS, and cognitive waveforms. Experiment 25a – TDRS-K Autotrack: Kick-off meeting at GSFC held on Sep. 17 Draft Experiment Plan started Experiments Status

8 General Experiment Support Activities Experiment Development System (EDS): Breadboard SDRs and Avionics Systems for Initial Experiment Development – Provides new experimenters a system for waveform development/testing Less fidelity than GIU; less restriction on scheduling/operations Working on remote access capability – IT security issues – Held EDS Design Review, proceeding with component procurement and fab Completed Installation, Functional Verification, and part of Performance Characterization of GIU GPS (in support of Experiment 4 / JPL GPS) Verified GIU Traveling Wavetube Amplifier Pre-Amp circuit design – For final Ka-Band Waveform V & V on the Scan Testbed GIU, the Spare LRO TWTA will be utilized. – When performing V & V, the Spare LRO TWTA will have to be driven into saturation the same amount as that of the Flight System. – Now proceeding with fabrication, assembly, and installation of the Pre Amplifier on the GIU.

9 RF Subsystem Checkout Operations – 10/15: Harris/SN-HGA – First Ka-band receive test Successful RF subsystem test Initial review of antenna pattern looks good – 10/16: GD/SN-LGA, NEN-LGA – First transmit test NEN-LGA test with Space Network is in support of NEN power level troubleshooting – 10/17: Harris/SN HGA – First closed loop, Ka-band transmit tests Continued closed loop RF lock through ISS reboost Upcoming: – 10/18: RF Subsystem Checkout complete – 10/22: Antenna Characterization begins 9

10 Other Technical Issues in Work Ongoing NEN power level investigation ISS inhibits (EVR, EVA, visiting vehicles) continue to challenge planning – Flight rules being re-evaluated based on new/updated RF radiation limits 10
