AMS02 Functional Integration Test FIT

AMS-02 Functional Integration Test (FIT)

• October 21, 2004
• Presenter 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 STS and ISS test facilities
  within the SSPF
• FIT will utilize the AMS-02 front-end avionics
  crates on table-tops (not the entire payload)
• FIT is designed to verify end-to-end data flow in
  a high fidelity development test
• 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)
• Target Date for test January 18-28, 2004

FIT Setup

• FIT testing is broken into two test setups, one
  for STS and one for ISS
• STS testing in the Cargo Integration Test
  Equipment (CITE) Stand
• ISS testing in the Payload Test and Checkout
  System (PTCS) Facility
• AMS-02 Hardware to include
• Qualification Unit J-Crate and JPD
• Low fidelity Model AMS Crew Operations Post
  (ACOP)
• Engineering Unit Power Distribution System (PDS)

STS Testing

• STS testing will include
• Power (including T0 for prelaunch and from
  Orbiter (APCUs) for in-flight) routed through AMS
  Power Distribution front-end
• Data Compatibility Testing
• LRDL Data (1553) testing (T0 and in-flight)
• Will test RT4 and RT 28
• Verify data handling between OIU, PDI/PSP, and
  Ground still yields expected end data/format
• High Rate (RS-422) testing (T0 and in-flight)
• Redundant data sets
• bent-pipe Ku throughput
• recorded on Digital Data Recorder System (DDRS),
  STS provided PGSC with interface board and
  cabling to PDIP
• 2Mbps

STS Data Flow
OIU Orbiter Interface Unit PDI Payload Data
Interleaver PSP Payload Signal Processor POCC
Payload Ops Control Center

• This segment omitted for test

This segment will be simulated by KSC command
terminals and AMS Ground Support Computers

ISS Testing

• ISS testing will include
• Power simulation with simulated line loses
• Data Compatibility Testing
• LRDL Data (1553)
• Will test unique design implementation
• Four protocol engines acting as one RT
• Each wakes in monitor, first command
  no-response but identifies which PE to go to RT
• Verify data handling between PLMDM, APS, HRFM,
  and MSFC (EHS) still yields expected end
  data/format at POCC
• HRDL testing
• AMS-02 generating 2Mbps continuously
• AMS-02 Crew Operations Post (ACOP), located in
  Express Rack, records data, maintains continuous
  communication with AMS-02, and provides burst
  capability for downlink of playback data

Issues/Concerns

• Procedures development went well, but more work
  needs to be done
• Umbilical Mechanism Assembly testing
• ACASS simulator
• UMA Active/Passive halves
• Back-up plans developed for Passive UMA (Flight
  or GSE)
• Power Distribution System Engineering Unit
  schedule is tight
• Safety Package for test must be worked with Paul
  Kirkpatrick/KSC
• PRCU testing need procedures from CGS
