Résumé
An important subject in AMS02 previous termexperimentnext term would be to perform measurements of the arrival time of the photons on previous termanext term scale of few μsec for the Transient Gamma Sources, mainly Pulsars, Blazars and Gamma Ray Bursts. This may be possible if each trigger correlated with previous termanext term detected cosmic particle, acquires previous termanext term precise time stamp provided by previous terma spatial GPS receivernext term which will also be used to synchronize the internal clocks of the previous termAMS-02next term DAQ system. The TOPSTAR 3000 D previous termGPS receivernext term characteristics are described. The built in procedures for the integration of the previous termGPSnext term module in the DAQ and Trigger systems are presented. The dependence on the flight orbit, ISS in case of previous termAMS-02next term mission is studied. In final, the monitoring requirements and the first results of tests are discussed.
