FIELD: azimuthal orientation of mobile objects having gyrostabilizers in control systems. SUBSTANCE: sensitivity axes of two horizontal gyros are leveled together with platform on which they are placed in initial position with the aid of two horizontal accelerometers. Sensitivity axis of vertical gyro is brought to vertical. They are switched over to mode of gyro by formation of correction moment with the help of torque generator of vertical gyro proportional to deviation angle of platform from plane of horizon and of additional correction moment proportional to derivative of this angle. EFFECT: reduced time of determination of meridian direction by means of three-axes gyrostabilizer without loss of accuracy. 1 dwg
