1 MCCS Status Update SOFIA SITR 2-19-10 Kendall Mauldin SOFIA Platform Project Flight Systems Lead SOFIA Stratospheric Observatory for Infrared Astronomy 1

2 Open Door MCCS Overview The MCCS Consists of 10 Subsystems –Platform Interface Subsystem (PIS) –Power Distribution Subsystem (PDS) –Mission Audio Distribution Subsystem (MADS) –Workstation Subsystem (WS) –Network Subsystem (NWS) –Time Distribution Subsystem (TDS) (IRIG/NTP) –Video Distribution Subsystem (VDS) –Archive Subsystem(ARS) –Data Acquisition Subsystem (DAS) –Water Vapor Monitor(WVM) 2

3 MCCS Current Status Verified and operational in open door configuration – Currently supporting envelope expansion flight series Modifications and installations in preparation for FORCAST line-ops are on-going (non-interference to envelope expansion) – Currently in a three week downtime where no envelope expansion flights are occurring, allowing us to complete many installations and mods in preparation for FORCAST Line-ops Engineering build to support FORCAST is being checked out in integration labs

6 FORCAST Line Ops/ Short Science MCCS Configuration

7 Preparations for FORCAST Line-ops During current three week downtime: – Installation of several additional fiber optic lines, wiring, brackets, LCD monitor, network infrastructure, network printer, MADS at PI Rack, PI Panel Ground Lugs – Informal check-out of PI Patch Panel MCCS Interfaces Includes safe-to-mate checks prior to connecting FORCAST instrument – Re-installation of MCCS UPS B – Installations of EB configured SDAS, PIS, network switches, Workstation, and TAIPS will be installed during the Observatory checkout period before Line-ops – Risk Mitigation check-outs of EB configured MCCS will be performed during observatory checkout period

8 Power Distribution Subsystem 8

9 PDS Status Currently operational in Open Door configuration – MCCS UPS B currently not installed for open door. Will be re-installed and checked out before FORCAST Line-ops – Most distribution for future configurations is already installed, but formal V&V would be completed prior to use of the future configuration power distribution Power Quality Notes for SI teams: – Both the UPS and FC power (115VAC, 60Hz) have been tested and verified to the following power quality specs (the 230VAC, 50Hz UPS will be tested to these standards as well): Voltage stability (zero to full load) +/- 3% of nominal (115 or 230 VAC) Frequency stability (zero to full load) +/- 1% of nominal (60 or 50 Hz) %THD: 5% max – The 28VDC power from the aircraft TRUs has been tested to the following power quality specs: Voltage regulation between 24 - 32 VDC at all load levels DC ripple amplitude no greater than 3Vpp at all load levels DC ripple frequency no greater than 5000 Hz at all load levels

10 MCCS Network Subsystem 10

11 Network Subsystem PNS Open door configuration Currently operational in Open Door configuration Scalable for future configurations FORCAST Line-ops configured units being checked-out in the integration labs

12 Network Subsystem 12

13 IRIG/NTP 13

14 IRIG/NTP Overview MCCS Forward Rack 5 IRIG NTP 14 Operational in open door configuration Scalable to support future configurations Supplies IRIG-B and NTP time base signals

15 Mission Audio Distribution System 15

16 MADS Status 16 Currently in “Open Door +” configuration, which includes expanded capability to support future configurations. Used for ground and flight ops FORCAST line-ops config will include MADS at the PI rack

17 MADS FORCAST/Short Science Config

18 MCCS Platform Interface Subsystem (PIS) 18

19 PIS On-Aircraft Configuration 19 Operational in Open Door Configuration EB unit loaded in integration labs for check-out prior to FORCAST Line-ops EB unit will be used for FORCAST Line- ops (will include connection to TA)

20 MCCS Workstations 20

21 Workstation Status 21 Currently one workstation installed in upper deck area for door controller. Operational for open door configuration Two additional workstations will be added for FORCAST Line-ops: TA Operators workstation, Mission Directors Workstation

22 GUI Design 22

23 MCCS S-DAS 23

24 S-DAS Overview 24 Provides connection between CDDS status data and flight test telemetry system Currently configured for Open Door configuration

25 Video Distribution System (TAIPS)

26 VDS (TAIPS) Status TAIPS not part of open door configuration (not currently present on aircraft) EB version of TAIPS is being checked out in integration labs, in prep for FORCAST Line-ops EB version of TAIPS will be installed for FORCAST Line-ops Connections to PI patch panel and imagers will be informally checked out prior to line-ops

27 PI Patch Panel Defined per MCCS_SI_05 ICD Installed and ready for FORCAST Line- ops check-outs
