Abstract: The present work attempts to characterize the accelerometric environment of the DSC-DCMIX1 thermodiffusion
experiment carried out in the International Space Station, from November 7th 2011 until January 16th
2012. Quasi-steady and vibrational/transient data coming from MAMS and SAMS2 sensors have been
downloaded from the database of the PIMS NASA website. To be as exhaustive as possible, simultaneous
digital signals coming from different SAMS2 sensors located in the Destiny and Columbus modules have also
been considered. In order to detect orbital adjustments, dockings, undockings, as well as, quiescent periods,
when the experiment runs were active, we have used the quasi-steady eight hours averaged (XA, YA and ZA)
acceleration functions as well as the eight hours RMS ones. To determine the spectral contents of the different
signals the Thomson multitaper and Welch methods have been used. On the other hand, to suppress the high
levels of noise always existing in the raw SAMS2 signals, denoising techniques have been preferred for
comparative reboostings considerations. Finally, the RMS values for specific 1/3 octave frequency bands
showed that the International Space Station vibratory limit requirements have not been totally accomplished
during both quiescent periods and strong disturbances, specially in the low frequency range.
