Late astrophysical and cosmological measurements have shown how ˜83% of matter of the Universe is dark and non-baryonic. Supersymmetric extensions of the Standard Model can provide a good candidate as main component of Dark Matter in the neutralino χ. In this framework, the magnetic spectrometer AMS-02 has been conceived for the precision measurement on board of the ISS of composition and energy spectrum of cosmic rays over a wide energy range, providing the potential to detect contribution to charged particle fluxes from neutralino annihilation. Due to the general faintness of expected Dark Matter contributions to cosmic ray spectra, interesting research channels are those for which the standard astrophysical background is expected to be low, like antimatter ones. Results of various MC analysis of AMS potential in the measurement of positron, antiproton and antideuteron fluxes are presented.
