Resum: The present work aims to investigate the degree of correlation existing between the
information contained in the ISS reduced quasi-steady accelerometric data and different
external mechanical disturbances (reboostings, dockings/undockings, berthings/deberthings
and Extra Vehicular Activities), compiled for the period 2009 to 2016. The eight hour mean
(Mean8h) and the eight hour root mean square (RMS8h) acceleration values, considered as
reduced data, have been extracted from the quasi-steady records provided by NASA Principal
Investigator Microgravity Services website. The advantage of applying the present strategy is
to drastically reduce the amount of information to be processed all along these eight years.
The Mean8h values have been used for the evaluation of trends as function of time while the
RMS8h ones were used to define the level (weak, medium and strong) of the different kind of
external mechanical disturbances considered. These criteria has been applied for
approximately four hundred selected disturbances, compiled in the Annex. Results indicate
that reboosting is always detected as a strong disturbance, while dockings/undockings, as
weak ones, having lower, though detectable level, depending on the type of spacecraft
considered. Extra Vehicular Activities are undetectable by the use of this reduced quasi-
steady approach. The inverse problem, in other words, knowing the value of the RMS8h one
could try to predict the kind of disturbance responsible of it, is thus feasible except for
berthing/deberthings and Extra Vehicular Activities.
