Beschreibung
Zusammenfassung:	FIELD: gyroscopy; inertial control systems of gimballess objects. ^ SUBSTANCE: proposed angular-rate sensor on base of modulation gyroscope has rotor made in form of parallelepiped on elastic equal-rigid suspension placed in sealed evacuate chamber rotating together with rotor, gas-dynamic spherical supports, engine, torque sensor brought of evacuated space, information reading and rotor control unit made in rotating coordinate system in form of capacitance-frequency transducer and sine-cosine converter, as well as moving-coil torque sensor consisting of coils and two permanent magnets at radial texture of magnetizing which are diametrically opposite in gyroscope rotor; magnets and magnetic circuits are located on rotor and torque sensor windings are located behind wall of hermetic ampoule and are threaded by radial field of permanent magnets. ^ EFFECT: enhanced accuracy of measurement of angular rate due to linearity of moving-coil torque sensor. ^ 5 dwg
