Status of Facilities

• MOC 3 Is Now Assigned As The Ground Station For
  IBEX
• Both long term operations (LTO) launch early
  operations (LEOPs)
• Original plan called for MOC 1 or MOC 2 for LEOPs
• Changes in GEO launch schedules created conflicts
  with IBEX schedule
• Addition of MOC 3 de-conflicts IBEX from other
  programs
• MOC 3 Integration
• LTO side is now being configured
• IBEX program asset
• LTO MOC testing from 11/13/07 to 1/04/08
• Components and furniture for LEOPS side are now
  in procurement
• Orbital capital asset
• LEOPs MOC testing from 1/17/08 to 2/12/08
• Back Up MOC
• Back up MOC is a laptop that can be transported
  to USNs facility should the MOC at Orbital go
  off-line for any reason
• Laptop is in-house
• MAESTRO application is loaded

Long Term Operation Center

• Located in Building 2
• Room is divided into two halfs
• MOC 3 - LEOPS (Not shown)
• MOC 3 - LTOC
• LEO Programs
• Dawn
• IBEX
• Each Program receives a horse shoe console for
  Daily Satellite Activities
• IBEX Console contains
• Mission Planning System (MPS)
• Primary Commanding String (CMD1)
• Backup Commanding String (CMD2)
• NASA Commanding String (CMD1)

LTO MOC Server Configuration

• Open Network (USN)
• Two synchronized V240 servers
  (Primary Backup)
• PC with dual displays connected to each server
  provides the user interface
• Both servers are synced to the archives
• Closed Network (NASA)
• TDRSS interface
• Single V240 server
• PC with dual displays connected to the server
  provides the user interface
• Server has a local archive

13
Ground Segment Status

• MAESTRO
• Current revision is at M009CF4R1
• Used throughout spacecraft CPT 2
• Loaded onto ground station machines
• MAESTRO validation test mid-November
• Mission Planning System
• Requirements analysis and Design completed
• MOC/ISOC STF Integration Test completed
• ACS Simulation ready for integration with MPS
• Beta version on schedule for 12/5/07 delivery to
  the MCC
• Final version on schedule for 1/4/07 delivery to
  the MCC
• Flight Dynamics Group
• Processing real tracking data received from
  Goddard FDF (Themis), which is a high
  eccentricity orbit similar to IBEX during the
  orbit raising.
• Reviewing Pegasus launch analysis to incorporate
  into initial orbit acquisition and orbit
  determination
• Universal Space Network
• Contract is in place ICD is signed
• CTV testing begins 12/4
• Network interface testing begins in late November

Operations Test Flow

• Tests described in
• S/C IT Plan (S924-PP6100)
• Ground Segment Test Plan (S924-PP1220)
• ISOC Test Plan
• Order of tests can be altered to accommodate
  schedule changes

16
Flight Ops Team Participation In IT

• Flight controllers will be allocated time on the
  spacecraft
• Gain exposure to ground station and spacecraft
  operations
• Exercise routine and contingency operations
  procedures
• Goal is to provide flight controllers with 100
  hours of exposure to spacecraft and ground system
• Specific activities during spacecraft and ground
  system integration and test provide good learning
  opportunities
