Title: Electrical Ground Support Equipment Schedule and Cost


1
Electrical Ground Support Equipment Schedule and
Cost
  • Scott Williams
  • Stanford University
  • scott.williams_at_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 TDF development
  • Support for IT activities

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
  • MSIT Support 03/05

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
