disturbances from typical sources of external loads, based on the measurements of acceleration
parameters in various modes.
In order to identify sources of micro-gravitational disturbances and other off-nominal dynamic
loads on the ISS structure, methodological and software/algorithmic means were developed for
mathematically recreating unknown parameters of external force loads, based on analysis of
telemetry from onboard microacceleration sensors. Inverse problems of this type are of
independent interest and have important applications in various areas of technology. It was
established that during dynamic operations, the level of loading on the structures of modules
did not exceed design values.
