Abstract
GAMMA-400 is a new space mission, designed as a dual experiment, capable to study both high energy gamma rays (from 100 MeV to few TeV) and cosmic rays (electrons up to 20 TeV and nuclei up to 10 eV). The full simulation framework of GAMMA-400 is based on the Geant4 toolkit. The details of the gamma-ray reconstruction pipeline in the pre-shower and calorimeter will be outlined. The performance of GAMMA-400 (PSF, effective area) have been obtained using this framework. The most updated results on them will be shown.
