<p>The present invention relates to an apparatus for attenuating vibrations of an accelerometer signal for an MEMS attitude heading reference system, and a method for same, the apparatus allowing, in a MEMS attitude heading reference system, the accuracy of roll, pitch and attitude estimations thereof to be raised by separating and blocking a continuous low-frequency dynamic acceleration signal, generated due to vibrations, from among the accelerometer signals which are combined with gyro sensor signals. An apparatus for attenuating vibrations of an accelerometer signal for an MEMS attitude heading reference system according to the present invention comprises: a gyro sensor attitude measurement unit (100) for extracting attitude information of a transporting body by analyzing a signal of a two-axis gyro sensor; an accelerometer attitude measurement unit (200) for extracting the attitude information of the transporting body by analyzing a three-axis accelerometer signal, wherein the attitude information is extracted for the transporting body for which vibration is attenuated by separating the dynamic accelerometer component, generated due to vibration of the transporting body, included in the three-axis accelerometer signal; and an integrated filtering unit (300) for integrating and outputting the attitude information output by the gyro sensor attitude measurement unit (100) and the accelerometer attitude measurement unit (200). Thus, the present invention can accurately estimate the attitude of a transporting body by means of the gyro sensor signal and the accelerometer signal for which vibrations are attenuated.</p> |
