The gyrocompass is typically located on the wheelhouse as close as possible to the center of roll, pitch and yaw of the ship, thus minimizing errors caused by the ship’s motion. Vessels operating in high latitudes must construct error curves based on latitudes because the errors at high latitudes eventually overcome the ability of the compass to correct them. Thus the directive force is maximum at the equator and decreases to zero at the poles. The directive force of a gyrocompass depends on the amount of precession to which it is subject, which in turn is dependent on latitude. This period can be reduced by aligning the compass with the meridian before turning on the power. Unlike a magnetic compass, it can output a signal to repeaters spaced around the vessel at critical positions.īut it also requires a constant source of stable electrical power, and if power is lost, it requires several hours to settle on the meridian again before it can be used. Any error is constant and equal around the horizon, and can often be reduced to less than one degree, thus effectively eliminating it altogether. Since a gyrocompass is not influenced by magnetism, it is not subject to variation or deviation. This causes the spin axis to trace a spiral instead of an ellipse and eventually settle on the meridian pointing north. (This is the period of oscillation of a pendulum with an arm equal to the radius of the earth.) To dampen this oscillation, the force is applied, not in the vertical plane, but slightly to the east of the vertical plane. Precession then causes the spin axis to trace an ellipse, one ellipse taking about 84 minutes to complete. The ballistics, usually four in number, are placed so that their centers of gravity exactly coincide with the center of gravity of the gyroscope. To make the gyro seek north, a system of reservoirs filled with mercury, known as mercury ballistics, is used to apply a force against the spin axis. With these two weights, the only possible position of equilibrium is on the meridian with its spin axis horizontal. It will tend to oscillate, so a second weight is added to the side of the sphere in which the rotor is contained, which dampens the oscillations until the gyro stays on the meridian. To make it seek the meridian, a weight is added to the bottom of the vertical ring, causing it to swing on its vertical axis, and thus seek to align itself horizontally.

First, the gyro must be made to stay on the plane of the meridian.To make it seek and maintain true north, three things are necessary. The rotor may weigh as little as half a kilogram to over 25 kg. The gyroscope in a gyrocompass can be pendulous or non-pendulous, according to design. The whole assembly is mounted on a base called the phantom. To make a gyroscope into a gyrocompass, the wheel or rotor is mounted in a sphere, called the gyrosphere, and the sphere is then supported in a vertical ring.
