Beschreibung
Zusammenfassung:	FIELD: navigation, applicable in production of gyroscopic instruments based on a dynamically tuned gyroscope in sea, air, ground, well-drilling navigation. ^ SUBSTANCE: the method is based on the fact that in the process of service the resonant frequency of the dynamically tuned gyroscope is tuned automatically by modulation of the DY variable signal in one axis by a square-shaped signal of frequency ft, and measurement of the response of the dynamically tuned gyroscope caused by this signal in the other axis. Supply frequency fgm of the gyro motor drive is changed by successive approximations until the response of the dynamically tuned gyroscope to the signal at frequency ft becomes equal to zero. ^ EFFECT: enhanced accuracy of determination. ^ 1 dwg
