AMS02 Functional Integration Test FIT

1
AMS-02 Functional Integration Test (FIT)

• P. Nemeth/LM

Objective

• The AMS-02 Functional Integration Test (FIT) is a
  risk-mitigation test designed to exercise the
  avionics and ground segments of the experiment in
  the ISS and STS environments
• FIT will utilize the PTCS and CITE facilities
  within the SSPF
• FIT will utilize the AMS-02 front-end avionics
  crates on table-tops (not the entire payload)
• FIT will integrate the flight segment consisting
  of
• AMS-02 avionics hardware and ACOP/LFM
• ISS and STS primary CDH interfaces
• The integrated flight and ground segments will be
  used to test most communications paths and
  command and data formats in the AMS-02 system
  from end to end (albeit local to KSC)

FIT Philosophy

• FIT testing is broken into two test setups, one
  for STS and one for ISS
• Both setups will utilize
• Qualification Unit J-Crate (experiment front-end
  interface for command and data handling)
• Low fidelity Model AMS Crew Operations Post
  (ACOP)
• Engineering Unit Power Distribution System (PDS)
• All testing is to be performed at KSC, no
  requirement for remote data routing (tapes will
  be available post-test for further remote testing
  as desired)

Status

• Kick-off TIM at KSC was held February 11, 2004
• Test presently scheduled for January 2005
• KSC monitoring potential conflicts with Return to
  Flight Activities
• CITE funding issue appears resolved for FIT and
  pre-flight
• PDS EU will be available for January test
  however, will only contain Side A

Action Item Status

• Rev 1 of FIT Test Plan out for Review
• STS-916 risk mitigation Orbiter software
  products to be utilized
• OI-30 Latest Orbiter Flight Software
• Super-format
• AMS High Rate data to fit within MPLM window
• ACOP connections to PTCS (fiber) cables to be
  supplied by KSC (existing)
• No method for CITE to test Critical Health Data
  for ISS (no S-band pipe)
• Interconnect diagrams from KSC side (PTCS and
  CITE) in work

Action Item Status

• APS availability being worked
• MSFC request to include HCOR in test
• STS commanding will be performed from KSC command
  terminal not AMS GSE
• Command list to be included included in Test Plan
• Need to track Collaboration Milestones
• Test Readiness Review (by telecon) in
  mid-December
• Telecon planned for July 28th with full team
