The gyro compass uses which operating method?

A gyro compass operates by using a rapidly spinning gyroscope driven by electricity. The spinning wheel creates angular momentum that resists changes in orientation, so the axis stays relatively fixed as the vessel moves. Mounted in gimbals, this steady reference is translated into a compass direction, with control systems helping align it toward true north. It isn’t powered by gravity, wind, or manual cranking—the essential method is electric power driving the gyroscope.
