FIELD: physics.
SUBSTANCE: method of determining heading is realised using an inertial device (1), providing measurements by means of at least one vibratory gyroscope (3), the method involving positioning the inertial device such that the axis of gyroscope lies in an almost horizontal plane; positioning the inertial device successively a certain number of times relative the vertical axis, the number of positions being greater than one; for each position, adjusting the electric turning angle of the vibratory gyroscope to a predetermined value (the predetermined value being the same for all positions), and determining the heading from the measurement results and the angle between said positions.
EFFECT: invention enables to use a simpler inertial device and increases measurement accuracy.
