The FERMI (former GLAST) Gamma-Ray Large Area Space Telescope is a satellite-based observatory that will study the gamma-ray sky in a wide energy range from a few keV to 300 GeV, allowing the investigation of many fields of the gamma ray astrophysics. FERMI will open a new and important window on a wide variety of phenomena, including black holes and active galactic nuclei, gamma-ray bursts, the origin of cosmic rays and supernova remnants and searches for hypothetical new phenomena such as supersymmetric dark matter annihilations. The primary instrument is the Large Area Telescope (LAT), which measures gamma-ray flux and spectra from 20 MeV to 300 GeV and is a successor to the highly successful EGRET experiment on CGRO. The LAT has better angular resolution, greater effective area, wider field of view and broader energy coverage than any previous experiment in this energy range. FERMI was integrated with a spacecraft in December 2006 and was launched in June 2008 from Kennedy Space Flight Centre (NASA). This paper is related to the commissioning experience with the LAT tracker.
