Abstract
A method of determining a heading by means of an inertial device () providing measurements by means of at least one vibratory gyro (), the method comprising the steps of: •positioning the inertial device in such a manner that the gyro extends close to a plane that is substantially horizontal; •orienting the inertial device successively in a predetermined number of orientations about a vertical axis, the predetermined number being greater than one; •for each orientation, adjusting the electric angle of the vibratory gyro to a predetermined value, the predetermined value of the electric angle being the same for all of the orientations of the inertial device, and taking a measurement; and •determining the heading from the measurements and an angle between the orientations.
