Test Facility Requirements for GLAMR deployment

  • Enclosed lab space of at least 400 sq feet for the laser systems
    • Most of the space will be a laser-controlled area
    • Should be within a 12m fiber run of the location of GLAMR sphere during the instrument test
    • Room temperature stability is required for better laser performance.  No more than 2F variation over a day.
  • Space for the integrating sphere and electronics rack in front of the instrument during the test (~30 sq feet)
  • At least three 20A circuits in the laser-controlled area and one 20A circuits in front of the instrument under test
  • a dry gas line for nitrogen purge
    • ΒΌ in swagelok tube fittings
  • desk space outside of the laser-controlled area
  • At least 2 seats for analysts
 

Typical Schedule for Travel Test

  • Initial discussions (as far before the test as possible)
    • Establish a rough instrument test date
    • Establish basic test outline (wavelength range and step sizes, radiance levels, light/dark times)
    • Establish requirements on the GLAMR system for the test (stability, uncertainties)
  • If GLAMR needs improvements, start on them until ~1 year out from test
  • 1 year before test: Schedule discussions begin in earnest
    • Work out test conditions (TVAC/ambient), how long will proposed measurements take, will they fit in the allotted time on the instrument calendar
    • Start bi-weekly meetings for with instrument test team and cal/val or science analysis team to communicate test details
    • Site visit by GLAMR team to review allotted lab space and test environment
  • 4-6 weeks before test: the GLAMR facility is set up in the allotted space at test site
    • Pre-ship review confirms that GLAMR is ready for the test
    • Gets GLAMR on-site and functional off the critical path
    • Perform initial calibration of the GLAMR system, required for instrument test
  • If there are additional optical elements in the test (ie a TVAC chamber window), an additional calibration is run when possible)
  • 2-3 days before test: GLAMR personnel return on-site to verify system functionality
  • 1 day before test: align sphere in front of instrument, run dry run measurements
  • Instrument test
    • OLI, VIIRS, OCI all required 11-14 days of two shift GLAMR operations
    • GLAMR does not have the personnel to support three shifts
    • At the end of test, a consent to break meeting establishes that all requirements have been met and GLAMR is free to move the sphere
  • 1-7 days after test: GLAMR runs another calibration to verify stability of the GLAMR system
  • The End: GLAMR packs facility and ships home
