Abstract
Official abstract text for this publication.
A disturbance correction device comprises a disturbance detector configured to detect and output a high frequency component of a measurement signal from an inertial sensor and a level converter coupled to the output of the disturbance detector. The level converter is configured to convert the high frequency component to a direct current (DC) signal. The disturbance correction device also comprises a compensator coupled to an output of the level converter and configured to compare the DC signal with a plurality of thresholds. When the DC signal passes one of the plurality of thresholds, the compensator is further configured to output a respective process noise increment to a Kalman filter. The respective process noise increment corresponds to the passed threshold.
