The Large Area Telescope (LAT) on the Gamma-ray Large-Area Space Telescope (GLAST) satellite observatory, to be launched by NASA in 2008, will survey the sky in the energy range from 20 MeV to >300; GeV. The detector subsystems of the LAT - a pair-conversion tracker, a scintillating crystal calorimeter, and a plastic scintillator anticoincidence shield - will provide much greater angular resolution, effective area, and field of view for gamma rays than the highly successful EGRET detector on the Compton Gamma-Ray Observatory. Operations support and science data processing for the LAT instrument on GLAST will be performed by the LAT Instrument Science Operations Center (ISOC) at the Stanford Linear Accelerator Center (SLAC). The ISOC supports GLAST mission operations in cooperation with other GLAST mission ground system elements and supports the science research activities of the LAT collaboration. The LAT instrument has been constructed and integrated onto the spacecraft. Concurrently with instrument testing, an extensive program of instrument performance analysis and science analysis software development is underway, driven by a series of simulated data challenges that span from low-level event reconstruction to generation of astrophysically interesting quantities, e.g. spectra, lightcurves, sky maps. Here we summarize the LAT instrument design and performance, the role and activities of the ISOC and the expected science results.
