Abstract
A method and apparatus for calibrating a gyro-sensor, by which a gyro-sensor can be calibrated using data which is obtained by measuring an angular velocity and a gyro output value of a moving body equipped with the gyro-sensor. The method includes measuring an angular velocity of a moving body and an average output value of the gyro-sensor when the moving body, equipped with the gyro-sensor, rotates, obtaining data about a characteristic equation of the gyro sensor using the measured angular velocity and the average output value and storing the data, and calibrating the gyro-sensor using the stored data about the characteristic equation.
