In a gyrocompass in which a gyro is housed in a gyro case with a spin axis arranged substantially horizontal, a container is provided for surrounding the gyro case and for containing a liquid. A suspension wire supports the gyro case within the container and a supporting device is provided to support the case with three degrees of freedom. A vertical follow-up device ensures that the container follows the gyro case around a vertical axis. A detector supplies a detected signal to the follow-up device to produce a follow-up error responsive to displacement and twisting of the suspension wire so that a damping torque is applied to the gyro case. A delay element supplies the detected signal to the follow-up device to produce a follow-up error therein. |
