The MK 37 VT Digital Gyrocompass Equipment contains an electromechanical gyrocompass with three precision gimbals. The gimbals and additional electromechanical components compensate for the earth's rotation and gravity while taking advantage of gyroscopic inertial properties. The result is a gyrocompass that automatically seeks and aligns itself with meridian pointing toward true north. A gyrosphere containing a gyroscope rotor is immersed in silicone fluid and is designed and adjusted to have neutral buoyancy.
