Resumen
The AMS-02 instrument has been installed on board of the International Space Station and is taking data since May 19th 2011. One of the key subdetectors of AMS-02 is the silicon microstrip Tracker, designed to precisely measure the trajectory and absolute charge of cosmic rays in the GeV-TeV energy range. This report presents the Tracker online operations and calibration during the first two years of data taking in space. It covers several aspects of the detector stability and calibration, such as dead and noisy strips, pedestals and temperature dependence, used for selecting good data for physics analysis. In addition, the method for evaluating the track reconstruction efficiency is discussed, which uses other subdetectors for an independent estimation. The results of the track efficiency, that are used in the calculation of cosmic rays fluxes, are presented.
