1 GLAST LAT Arrival at Spectrum Assuming That the LAT Transport Container Arrives on Flatbed Truck Question: Can Transport Cover Support Crane Lift With LAT inside (Lift Points and Cover to Base Fasteners)?? –Yes? Needs to be Proofloaded Accordingly –No? Can the Design be Changed? Operation #1: Preferred Off-Load: Flatbed Truck Backs into Receiving Area Off-Load Truck Using 10 Ton Facility Crane Red Arrows Show Path to I&T Highbay for Op #2 LAT Activities at Spectrum Astro Environmental Test Area 7200 sq.ft Horn Rm. Lav S/V GSE Area 1220 sq. ft. Electrical Room TBD Fire 29' x 40' Acoustic Test Cell Change Room 170'-0" Shipping Receiving 54' W X 54' L X 25' H (10 ) Ton Crane Area

2 GLAST LAT Activities at Spectrum Astro Operation #2: Transfer LAT to I&T High Bay –Question: Can SLAC Perform LAT Functional Testing and Inspections While Installed in the Transport Container Base? –Connector Access, Cooling/Purge Access, etc.? –Is it Smart to Transfer the LAT to the Rotation Stand? –Pro – Rotation Stand has Casters for Moving Into I&T High Bay –Con – Additional Handling –Can Caster Jacks be Added to Transport Container Base Design? »Allows Movement of Container Base Without Having to Place Container on Some Kind of Roller –Ops #2 and #3 May be Swapped Pending Answers/Discussion Operation #3: Remove Transport Container Cover –Use SLAC LAT Lift Fixture –Need Proofload Tags on sling as Well as Certifications –Container Cover Proofload –Assuming LAT is Bagged Inside Container

4 GLAST LAT Activities at Spectrum Astro LAT EGSE Setup and Checkout How Much Space do You Need? What Kind of Electrical Outlets do You Need (i.e. Anything Special)? How Much Time do You Need? Current Calibrations, and Do You Need to Re-Calibrate During Obs. I&T? What Kind Of Support Do You Need From Spectrum? LAT Post Ship Inspections What, How Long, Spectrum Support? LAT Post Ship Functional Testing What, How Long, Spectrum Support?

5 GLAST LAT Activities at Spectrum Astro LAT Integration with Spacecraft Use SLAC Provided LAT Lift Fixture and Grid Perimeter Ring Hoist Out of Container Base (or Rotation Stand), Move over to Spacecraft, Lower onto Flexures, Install Bolts Disconnect/Remove Grid Perimeter Ring From LAT Radiator Installation What Are They Shipped In? Pre-Installation Checkout/Inspection? Use SLAC Provided Lift Sling Installation Sequence –How are They Attached? Alignment What are we Measuring? Should we be Doing This Before Radiator Installation?

6 GLAST LAT Activities at Spectrum Astro LAT/Spacecraft Functional Testing Interface verification (safe-to-mate) Prior to Electrical Connection Spacecraft to LAT Functional Testing –LAT Database Merged With Spacecraft Database Long Before This (PSR – 6 months) LAT Stand-Alone Testing??? (LAT CPT??) Observatory Testing LAT CPT Combined with Spacecraft CPT to Form Observatory CPT LAT Data fed to LAT EGSE Thru Spacecraft I&T Rack LAT EGSE Connected to LAT for Troubleshooting LAT Cooling?? Environmental Testing Acoustics and Sine Vibe Instrumentation –Same as LAT Standalone Tests? TVAC –Instrumentation and Ramp Rate
