1. NASA MSFC Mission Operations Laboratory MSFC NASA MSFC Mission Operations Laboratory Obsolescence Driven Avionics Redesign (ODAR) Status POIWG #32, July 2012 Johnathan Carlson Data Management Coordinator (DMC) MSFC/EO30 256-544-0705 johnathan.a.carlson@nasa.gov Approved for Public Release; Distribution Unlimited

2. NASA MSFC Mission Operations Laboratory MSFC Page 2 Completed Tasks  SGANT-2 installed on 2J/A  Redundant Ku receiver  APS install occurred September 2, 2011  No issues at activation  Minor sync issues have been discovered in 10 months of operations  Mod Kits launched on ULF-7 which included cables for ODAR  APS v6.2 software load occurred on April 13, 2012  Successful

3. NASA MSFC Mission Operations Laboratory MSFC Page 3 Upcoming Changes  Video after ICU Install  Video is still restricted by JSC  Though the capability will not exist at ICU install, the plan is to allow most payload rack video to be routed directly to MSFC for distribution  Project is currently reviewing the quality of the ICU video encoding  DFP Viewer  Due to the complexity of the planning system, DMCs will be moving to a software based DFP  If users are currently using a paper DFP, the DMC team is looking to phase that out early in Increment 33/34  Requires EPC or PPS launchpad and DFP Viewer privileges  Ku-band Forward  Allows payloads to access hardware on payload LAN from the ground  Change request review just closed  Ops concept still in development

4. NASA MSFC Mission Operations Laboratory MSFC Page 4 Upcoming Changes  APS Spare Upgrade  Currently only legacy APS spares are onboard  Provides a fully redundant on-board spare  Non-ODAR Change  New HD camera system using JSL instead of HRDL for downlink  Replaces MPC  Implementation currently set for after ICU activation

5. NASA MSFC Mission Operations Laboratory MSFC Page 5 ODAR Schedule  All of the following dates are NET  April 2012 – Recable activities begin (Prep work for ICU install)  July 2012 – 2 iPEHG and 1 ICU Launch on HTV-3  November 2012 – iPEHG Installation (US LAB Only)  TBD – APS spare card upgrade (tentatively prior to ICU activation)  January 2013 – ICU Activation  TBD 2012 – 2 iPEHGs launch (48P and SpX-1)  TBD – iPEHG-A Installation (Columbus)  TBD – APS v6.3 software load (CCS R12 must be complete)  Late 2013 – Ku-band forward

7. NASA MSFC Mission Operations Laboratory MSFC Page 7 Current Data System Constraints  8 HRDL Channels  7 reserved for specific users  1 shared by IPU, MPC, CIR, etc.  129.6 Mbps raw rate (150 Mbps with overhead) Ku Band Downlink  31 Mbps reserved for specific users  99 Mbps shared by MRDL users, HRDL users, higher quality video, higher data rate COL HRM and AMS  8 Mbps PEHG Gateway Limit  Scheduling a second PEHG-GW requires a HRDL channel  Can schedule 7 Mbps on PEHG-1 GW, 8 Mbps on PEHG-2 GW, and a coordinated amount on the LEHX.

NASA MSFC Mission Operations Laboratory MSFC Page 8 Current Onboard Data and Video System APS1APS2 VTR Rack/ Location Rack/ Location PEHG1 US ER US ER PLMDM HRFM HCOR PEHGs are 10Mbps PEHG2 SGTRC SGANT VBSP PEHGA N2 ER N2 ER LEHX VSU VBSP digitizes video signals HRFM muxes digital data and digitized video from VBSP 12 inputs into 1 stream HCOR records and/or passes data through to HRFM. It can also packetize bitstream data. APS only routes signals HRM JAXA’s upgrade to PEHG-J

9. NASA MSFC Mission Operations Laboratory MSFC Page 9 Phase 1 ODAR enhancements to Onboard Data and Video System New or Modified ORUs:  Modify the Automated Payload Switch (APS)  Replace:  Controller and Switch Card  Replace the power supply  Improvements:  Aggregation of multiple input data streams into a single output data stream – eliminating the 8 channel HRDL bottleneck.  Provide increased Health and Status from the ORU, including actual measured data rates from each input  Provide Dark Fiber Detection  Automatically disconnects any routes that have a dark fiber condition caused by an upstream source Tx shutdown

10. NASA MSFC Mission Operations Laboratory MSFC Page 10 Phase 1 ODAR enhancements to Onboard Data and Video System iAPS Install  On-orbit was performed Sept 2 nd, 2011  Plan is to leave one APS powered for Ku downlink while the other is upgraded  This will cut the number of available HRDL channels down to Four (4) during the crew upgrade operations  No plan as of yet which APS will be first  Will assess per APS usage just prior to work in order to minimize the impacts to operations  Newly installed iAPS will go through initialization and checkout  Will be operating in a mixed fleet mode during this time  We will hold this configuration for a short time (worst case is “days”)  At the end of the checkout, any necessary swaps will occur (PLMDM, PEHG) to configure to the iAPS and the other APS will be removed and upgraded  More than Four (4) downlinks will be available during this time as the iAPS will be capable of muxing inputs

11. NASA MSFC Mission Operations Laboratory MSFC Page 11 Post-iAPS Installation Data System Constraints  129.6 Mbps raw data rate (150 Mbps with overhead) Ku Band Downlink  31 Mbps reserved for specific users  99 Mbps shared by shared HRDL users, higher quality video, higher data rate COL HRM and AMS  Constraint relieved with installation of the ICU in January 2012 – 259 Mbps raw data rate (300 Mbps with overhead) Ku Band downlink  8 Mbps PEHG Gateway Limit  Scheduling a second PEHG-GW requires a HRDL channel  Constraint relieved with installation of iPEHGs in Nov 2011 – 100 Mbps gateway

13. NASA MSFC Mission Operations Laboratory MSFC Page 13 Additional ODAR enhancements New or Modified ORUs:  Replace the Payload Ethernet Hub Gateway (PEHG) with a 100BaseT Ethernet switch – eliminating the 8 Mbps MRDL bottleneck  Replace the following ORUs with the Integrated Communications Unit (ICU) –Video Baseband Signal Processor (VBSP) –High-rate Communications Outage Recorder (HCOR) –High Rate Frame Multiplexer (HRFM) –High Rate Modem (HRM) –Ku-Band Forward Link Receiver –Video Tape Recorders (VTRs) –OCA Router

14. NASA MSFC Mission Operations Laboratory MSFC Page 14 Additional ODAR enhancements ICU Capabilities:  Provide the applicable functional capabilities of the ORUs it replaces  Support 300 Mbps and 25 Mbps data rates on the return and forward links, respectively  Provide interfaces to the audio system for audio embedded in digital video encoding and two-way audio communications  Provide up to 8 hours of video recording (digital)  Provide simultaneous record and playback  Support operations in a contingency critical command, audio, and telemetry mode  Provide multiple user access to the Ku-band forward link
