3. Glenn Research Center SAMS ICU Upgrade Background CR #13240 approved a SAMS ICU Upgrade to replace the system that is based upon the 760XD laptop in an Express ISIS drawer. The upgrade consists of taking the SAMS flight software running on NetBSD and porting it to run on Ubuntu. The changes to the code include using the RIC Bypass mode to send telemetry, connecting to an ISS NTP server for time, and minor enhancements to provide for better operation support. The SAMS team is seeking to educate the JSC Mission Planning, MSFC CADRE, and the ISS scientific community on the details of the SAMS ICU Upgrade effort and the requirements verification approach –This is a software only effort. SAMS team is NOT flying a laptop or any other associated hardware –A distribution/ghosting disc will be manifested as a backup capability 3

4. Glenn Research Center SAMS ICU Upgrade What is SAMS? Continuously powered, distributed vibratory/transient acceleration measurement system in the frequency range 0.01  f  300 Hz Operating on the ISS since Flight 6A, April, 2001 –Large knowledge base of acceleration data –Extensive ISS operational experience –Operational system for over 20 years supporting the ISS, Shuttle, Mir, and ground operations Provides real-time downlink of acceleration data Automated ground systems process and archive the acceleration data received from the ISS –Spectrogram data are available near real-time on the PIMS website –Data are made available to the ISS Vehicle and the ISS Payload communities within 24 hours of their on-board acquisition –High level plots called Roadmap Spectrograms are automatically generated to provide a quick look at the overall ISS microgravity environment 4

5. Glenn Research Center Description –New laptop shell Utilize an ISS laptop T61p with a custom SAMS software load (no standard SSC software load installed) and the laptop connected directly to the Payload LAN –SAMS Control Unit Power Interface Current SAMS ICU Drawer will no longer be powered SAMS Control Unit will be powered like the AMS laptop via ER#6 PS-28 Junction Box – power to SAMS Control Unit will be “always ON” (I think??) –SAMS Control Unit Data Interface SAMS Control Unit will only use the logical data interface for the ER#1, Drawer #2 location for its commanding and PLMDM H&S connectivity SAMS Control Unit will be connected to the ISS Payload LAN via LAB1D1 ISL Interface Panel SAMS Control Unit will use an ISS NTP server instead of the RIC for data time stamps –SAMS Control Unit Location SAMS ICU will be located on a bogen arm in front of ER#1/MAMS location –SAMS Control Unit Software New Ubuntu OS will be deployed Enhancements will be included in this software release, which improve ground operations for the SAMS team 5 SAMS ICU Upgrade Description of What Does Change

6. Glenn Research Center Operations Changes for Commanding −SAMS Control Unit commanding through ER#1 will require ER#1 to “bridge out” SAMS commands to the ISS Payload LAN Operations Changes for Data −SAMS Control Unit will operate in RIC bypass mode and send data directly to the PEHG for downlink (APIDs 890 and 898) −SAMS H&S packet will be sent to ER #1 for the SAMS Control Unit. The packet type and length remains the same −SAMS H&S packet will have new descriptions for 4 MSIDs (temperatures) SAMS to provide PRO with the MSIDs and new description PDL will be updated starting in IN39 database Operations Changes for Documentation −New SAMS procedure will be required for ghosting the SAMS image on a T61p laptop −Engineering tests at SSITF will identify SAMS Control Unit lockup procedure changes, including associated Ground Command Procedures 6 SAMS ICU Upgrade Description of What Does Change

7. Glenn Research Center Description –RTS Drawers, Embedded EE’s, and TSH-ES sensors There are no software changes to the operational software for any of these units There are no communication changes between the SAMS sensor hardware and the SAMS Control Unit –SAMS Commanding Interface All SAMS commands are still routed through the SAMS Control Unit –SAMS Control Unit Data Interface SAMS Control Unit will process all data the same - data from each EE and TSH-ES will still go to the SAMS Control Unit and the SAMS Control Unit will packetize the data and send data to the ground There are no data rate changes for the SAMS hardware – No DMC or EHS data system changes are required SAMS will use the same MAC address from the SAMS ICU 760xd laptop, so no LEHX configuration file change is required –SAMS Control Unit Power Interface SAMS will still need PRO to power on SAMS sensor hardware, although SAMS testing may ease or eliminate this for SAMS Control Unit recovery scenarios 7 SAMS ICU Upgrade Description of What Does Not Change

8. Glenn Research Center Operations Constants −Crew will still be required for laptop power cycles/laptop lockups −PRO support will still be required for SAMS Control Unit lockup recovery 8 SAMS ICU Upgrade Description of What Does Not Change

18. Glenn Research Center SAMS ICU Upgrade Why is SAMS Important? AMP Customers can be divided primarily into three categories: Microgravity Principal Investigators –AMP provides support to a variety of investigators and a variety of disciplines, typically through direct measurement support Active Rack Isolation System (ARIS) Combustion Integrated Rack (CIR) Fluids Integrated Rack (FIR) Microgravity Science Glovebox (MSG) DECLIC Investigation ROBONAUT Disturbance Characterization per LIS Request International Partner Support –Provide data processing and storage for JAXA Microgravity Measurement Apparatus (MMA) equipment located in the JEM –Materials Science Research Rack (MSRR) support –GEOFLOW experiment support in the Columbus Fluid Science Laboratory (FSL) –MARES commissioning support and initial checkout –ACES Atomic Clock investigation in the Columbus Module 18

19. Glenn Research Center SAMS ICU Upgrade Why is SAMS Important? AMP Customers can be divided primarily into three categories: ISS Vehicle Support –Testimonial Information James P. Smith (ES211), email dated 1/30/2012 –“…but SAMS has been invaluable over the last several years from both a microgravity and vehicle environments perspective. Directly to the microgravity requirements, we have used SAMS data to close out microgravity requirements for HTV, ATV, and the Crew Quarters racks. “ –Per Mike Laible (Boeing, JSC-OA), ISS Vehicle Loads and ISS Vehicle Microgravity uses SAMS data Daily Daily use includes quick look at pre-generated Roadmap Spectrograms –Used for Exercise monitoring and any other large disturbances – unplanned events –Easy user Roadmap Spectrogram interface for 24-7, over 10 years of historical data Once Quick Look performed, detailed analysis can be generated –Loads group has developed user tools to download SAMS data and perform time domain and frequency domain analysis (see Laible Example #1) Long term Microgravity Analysis Loads feels this is a critical piece of hardware for ISS station life, trending, microgravity and loads analysis 19

20. Glenn Research Center SAMS ICU Upgrade Why is SAMS Important? AMP Customers can be divided primarily into three categories: ISS Vehicle Support –SAMS data 24x7 availability allows the capture of unplanned significant microgravity events (see Laible example #2) as well as planned significant microgravity events –SAMS works in conjunction with EWIS, IWIS for planned microgravity events IWIS provides a measurement capability in Node 1, the FGB, and the Service Module SAMS not currently deployed in Node 1, FGB, or Service Module –Low frequency analysis for trending ISS fundamental modes (see Laible example #3) 20

21. Glenn Research Center 21 Vehicle Support Example #1: ISS Loads & Dynamics Quick Look Example of quick look discovering T2 Locked exercises Current IWIS, EWIS, SDMS systems are for planned events In addition to historical data, SAMS Spectrograms are used real time for quick calls on loading events Reboost, unusual rate during holidays Daily Review of Max G Automatic G threshold report

22. Glenn Research Center 22 Once Quick Look deems event significant, Loads GUI used for detail analysis GUI and saved historical data allows for quick comparison of previous events – 24-7 It must be noted that graphics are for demonstration and may not represent the same event Vehicle Support Example #1: ISS Loads & Dynamics Quick Look

23. Glenn Research Center Vehicle Support Example #2 GMT 174 Event Description: Unplanned Microgravity Event  On June 23, 2011, a large yaw RS MCS maneuver resonated the structure for over 10 minutes – RS FDIR tripped due to high measured rates at SM gyro. SAMS recorded the event, SDMS and IWIS were used for the docking portion (missed the maneuver portion).  Loads reconstruction showed ISS loads exceeded pre-flight predictions for maneuvers. SAMS data verified the reconstruction was accurate and identified specific structural modes were excited.  L&D/GN&C investigation concluded RS controller interacts with structural modes.  This anomaly could have remained undetected had SAMS not been active. Handover to RS MCS GMT 13:30 (t=0) Mnvr Start GMT 13:37 (t=420) Mnvr End GMT 14:17 (t=2820) Excitation GMT 13:40 (t=620s) Yaw thruster failure GMT 13:50:43 (t=1243s) Measured On-Orbit Accelerations (JEM SAMS) Frequency Content of Accelerations (JEM SAMS)
