LAT ISOC Activities

The LAT ISOC is organized to:
– Operate the instrument, in conjunction with other GLAST ground
elements
– Generate reconstructed LAT events and automated science
products
 Main Functions:
– LAT command planning and construction
– Instrument health and safety monitoring
– Maintain and modify LAT FSW and the LAT Testbed
– LAT calibration, performance verification and optimization
– Process and archive LAT data
– Maintain and optimize the software that produces science data
 Incorporates online and offline operations activities for the LAT
– Extends existing pre-launch activities into on-orbit operations
 Supports the LAT collaboration

Real-time commanding of the LAT through the MOC uses scripted PROCs
All LAT commands in the T&C database delivered to the MOC are included in
Narrative Procedures (NPs)
All procedures to be exercised during GLAST End-to-End tests
– Development schedule is tied to ETE schedule
Separate procedures for activities in GLAST Launch and Early Orbit period
(L&EO)
Contingency procedures included
PROCs are verified against LAT testbed before use with GLAST
