  1. Electrical Ground Support Equipment Schedule and Cost Scott Williams Stanford University scott.williams@stanford.edu

  2. Schedule • The schedule is driven by the delivery of electronics hardware units. • EM1 • EM2 • FSW Testbed • Qualification Unit • Flight Unit • Each provides increasing complexity and capability. • Other major duties are • Support for FSW development • Support for T&DF development • Support for I&T activities

  3. Evolutionary EGSE Development

  4. T&DF Integration & Test, I&T

  5. LAT I&T Plan

  6. EGSE Development & Test

  7. EGSE Deliverables Total Systems • Engineering Model 1 - 10 • Engineering Model 2/Qual Unit/Flight Unit - 4

  8. Milestones • EGSE PDR (Concept Review) 08/17/01 • LAT Instrument PDR 10/24/01 • DAQ Engineering Model 1 Development - EM1 EGSE Delivery 11/01 • Subsystem Development - EM1 EGSE deliveries 03/02 • LAT Instrument CDR 08/05/02 • DAQ Engineering Model 2 Development - EM2 EGSE delivery 09/02 • Flight Software Testbed Development - FSTB EGSE Delivery 12/02 • Qualification Unit EGSE Delivery 05/03 • Flight Unit EGSE Delivery 8/03 • Transition to IOC Maintenance 10/03 • Calibration Unit Beam Test 10/03 • LAT Environmental Testing 05/04 • MSI&T Support 03/05

  9. EGSE Schedule

  10. EGSE Schedule

  11. EGSE Schedule

  12. EGSE Schedule

  13. Labor Loading HEPL Staffing for IOC/EGSE includes hiring profile of 1 FTE staff in FY02, FY03 and FY04 until stabilizing at 5 FTEs in FY04. Total EGSE staffing is approximately 2 FTEs in FY02/03

  14. Level 4 Budget by FY EGSE labor estimate is low and does not include configuring multiple systems

  15. Issues & Mitigations • Multiplicity of systems required to support parallel development efforts • Enforce commonality of basic infrastructure. • Provide data distribution over ethernet to support subsystem specific EGSE and engineering data displays. • Use COTS hardware and software as much as possible to control cost. KISS. • Leverage RTOS interface systems development off flight software development. • Leverage out-years EGSE maintenance from IOC. • Initial need date of 11/01 is aggressive • Begin development immediately. • Leverage recent Balloon Flight EGSE development. • Obtain subsystem buy-in via IPT. • Trade studies delayed by Balloon Flight • Perform in parallel to EM1 development
