\n Three calibration campaigns of the spectrometer SPI have\nbeen performed before launch in order to determine the instrument\ncharacteristics, such as the effective detection area, the\nspectral resolution and the angular resolution. Absolute\ndetermination of the effective area has been obtained from\nsimulations and measurements. At 1 MeV, the effective area is 65 cm2 for a point source on the optical axis, the spectral\nresolution ~2.3 keV. The angular resolution is better than\n2.5° and the source separation capability about 1°. Some\ntemperature dependant parameters will require permanent in-flight\ncalibration.\n\n
