The experiment, installed on the International Space Station (ISS), has so far collected 54 billion of events originated from cosmic rays, out of which 41 billion have been analyzed. The results show an excess of positrons in the range from 8 to 275 GeV, which is compatible with a dark matter particle (neutralino) of about 1 TeV of energy.

In order to confirm the dark-matter origin of the result and to exclude other possible explanations, the AMS collaboration will continue the analysis and increase the statistics at higher energy.

SITAEL contributed to the construction of AMS-01 and AMS-02 by developing and producing most of the electronics for all its sub-detectors. AMS-02 was installed on the ISS in May 2011 and it is properly working since then.
