ABSTRACT:
A method for correcting the output sensitivity an angular velocity detector, in which, a first running directional data of the mobile object is successively calculated in accordance with the output signal of the angular velocity detector, a second running directional data of the mobile object is successively calculated in accordance with the positioning data obtained from a plurality satellites, the sensitivity correction coefficient is calculated in based on the stored first and second running directional data, and the sensitivity correction coefficient is multiplexed by the output signal of the angular velocity detector, so as to correct the output sensitivity of the angular velocity detector. Therefore, the dispersion of the output sensitivity of the angular velocity detector is eliminated to improve the accuracy of output sensitivity.
