Telemetry Data Archive
  • Telemetry data is archived twice
  • The Data Capture System archives tlm files for
    offsite storage
  • Archive tapes are shipped to the offsite location
    and verified for reading
  • A feedback mechanism will be established to ack
    the SDP that a tape is verified or that another
    copy needs to be sent
  • The Data Capture System copies tlm files to the
    Pipeline Processing System
  • The Pipeline Processing System archives tlm data
    for local storage and acks the SDP when it is
    successful
  • Only when the SDP has received positive acks on
    both archive copies does it inform the Data
    Capture System to include the tlm file in the
    .arc file to the DDS, who is now free to remove
    the file from its tracking logic
  • The lev0 data on the Pipeline Processing System
    is also archived

Test Approach
  • Telemetry data is simulated with MDI data
    packaged in SDO VCDUs
  • Various telemetry pathologies can be created to
    validate telemetry processing
  • The DDS is simulated by packaging the VCDUs into
    files and injecting them into the SOC front end
    using the DDS/SOC protocol
  • The lev0 processing is validated by comparing
    input and output images
  • Timing analysis and throughput studies will be
    performed to evaluate h/w and s/w tradeoffs
  • Instrument sunlight tests will be used to
    validate the lev1 processing
  • Each s/w library and subsystem has a regression
    test suite that is run to verify each new CM
    release
  • Full end to end testing is accomplished via the
    mission IT plan
