The ISS microgravity acceleration environment consists of two regimes : the quasi-steady environment and the vibratory/transient environment; therefore, the measurement of the microgravity acceleration environment is best accomplished by two accelerometer systems. In the United States Laboratory Module, the measurement of these two regimes is accomplished by the Space Acceleration Measurement System-II(SAMS-II) and the Microgravity Acceleration Measurement System(MAMS). The vibratory/transient environment, consisting of vehicle, crew, and equipment disturbances and covering the frequency range 0. 01-300 Hz, will be measured by the SAMS-II.  2, fiche 1, Anglais, - acceleration%20environment

The objective of the Microgravity Acceleration Measurement System(MAMS) is to measure and report vibratory and quasi-steady acceleration within the United States Laboratory Module on the International Space Station. Vibratory acceleration, produced by mechanical equipment and crew activity, has an oscillatory nature with a frequency greater than 1 Hz.  2, fiche 2, Anglais, - vibratory%20acceleration

The acceleration-sensitive torque caused by radial unbalance due to noncoincidence of the flexure axis and the center of mass of the rotor. Under constant acceleration, it appears as a rotating torque at the rotor spin frequency. When the gyro is subjected to vibratory acceleration along the spin axis at the spin frequency, this torque results in a rectified drift.  2, fiche 3, Anglais, - radial%2Dunbalance%20torque
