The main document that regulates the staffing of ships navigating devices is SOLAS Convention.The Convention entered into force on May 25, 1980 In 1981 The International Maritime Organization adopted amendments to SOLAS-74.Under these amendments, the text of regulation 12,'The ship's navigation equipment' chapter 5 'Safety of Navigation' ,It includes requirements related to the installation on ships navigating devices.The adopted amendments entered into force on September 1, 1984.From this moment navigating devices installed on ships should have specifications no lower than those indicated in the documents.
A rose of a gyro course indicator (repeater) must be graded by one degree or part of a degree. Every 10 ° are marked with numbers from 0 to 360 ° clockwise.Lighting repeater should be sufficient for the removal of rate readings at any time(?).The brightness must be adjusted.
On the stationary vessel as well as rolling and pitching motion with a period of oscillation of 6 to 15, an amplitude of 5 ° and a maximum horizontal acceleration of 0.22 m / s2 at latitudes up to 60 ° gyro must come in meridian is not more than 6 hours following activation.
It is necessary that the gyro function reliably when subjected to vibration, moisture, temperature variations in the extent that can be positioned on the appliance installation, as well as in an alternating magnetic field.
The ship's power supply should provide continuous operation of the gyrocompass.Each device gyro must be protected from changes in current and voltage, overload in transient modes, as well as from accidental changes in supply voltage polarity.If there are multiple power supplies need to be able to quickly switch from one gyro one another.
The main instrument and gyrocompass repeaters for bearing must be installed parallel to the plane of the vessel with an accuracy of ± 0.5 °.Lubber(Heading?) line and the center of rose should be placed in the same vertical plane.Gyro must be Corrector speed deviation and signaling devices on the main fault.
