    摘要: A method for real-time calibration of a gyroscope, configured for supplying a value of angular velocity that is function of a first angle of rotation about a first angular-sensing axis that includes defining a time interval, acquiring from an accelerometer an equivalent value of angular velocity that can be associated to the first angle of rotation; calculating a deviation between the value of angular velocity and the equivalent value of angular velocity; iteratively repeating the previous steps through the time interval, incrementing or decrementing an offset variable by a first predefined value on the basis of the values assumed by the deviations during the iterations, and updating the value of angular velocity as a function of the offset variable.
