FIELD: navigation of moving objects. SUBSTANCE: proposed method consists in measurement of phantom acceleration by means of accelerometers. Components of absolute angular velocity of instrument trihedron connected with gyroplatform by means gyroscopes are determined. Then, components of absolute angular velocity of Darbu trihedron and its orientation relative to instrument trihedron are generated by signals of accelerometers and gyroscopes. Navigational parameters are generated by components of absolute angular velocity of Darbu trihedron. Gyroplatform is rotated at preset rate around one axis of gimbal mount having at least two axes and is swung around second axis at preset frequency characteristics. Then, similar parameters generated by main and additional navigational systems are compared in control unit and errors modulated at preset frequency are eliminated. EFFECT: enhanced accuracy. 1 dwg
