Abstract

An accelerometric measurement device with a return loop including accelerometer, a corrector generating a signal for correction of the position of the accelerometer, a closed return loop to apply this correction signal to the accelerometer, a detector to detect an error in operation of the accelerometer, and a modifying component making at least a first modification to operation of the corrector from its initial state to a modified operating state.
