    GYROCOMPASS

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.

  • The gyrocompass has the wide range of output signals. TG-8000 developed in compact case, consists of two blocks: master-compass & control unit.

  • The gyrocompass of TG-8500 has approval for use in high-speed vessels.

  • The same type of gyro also manufactured as brand  Simrad: GC-80 (TG-8000) & GC-85 (TG-8500).

  • The cost of gyro's TG-8000 under the order on market RK lower, than at gyro's with
    the similar parameters, that in total with the simplified maintenance
    is disputable advantage of this equipment.

  • is suitable for vessel speed to 70 knots (TG-8500)
  • high speed of processing (75 о/с)
  • high speed TX serial data (IEC61162-2)
  • Possible to connect external Heading Sensor
  • More easy for installation with 2 sets ( For the moun 2 gyro )
  • Function of the timer of start-up.

   Picking can change in dependence on the requirement of the customer.
  • The TG-8000/8500 model is developed on the basis of the previous versions of TG which have been established more than in 800 vessels and have shown high reliability, excellent working capacity and compatibility with the equipment.
  • Gyro TG-8000 designed according IMO standart for the mounting on different sea & river vessels, also type TG-8500 developed  for the high-speed courts.

        Picking can change in dependence on the requirement of the customer.
    • The system configuration can easily be adapted to each vessel's specifications.
      IEC 61162-2 high-speed code is available for the heading and rate of turn (ROT) outputs.
      A unique anti-vibration system enhanced by the velocity damping effect of high viscous oil, provides superior damping of vibration and decoupling of shock at sea.
      A small and lightweight container enhances the follow up speed. The gyrocompass changes smoothly and does not lag when a small vessel rapidly changes course.
      A space-saving design: the master compass can be installed on the autopilot stand.
      The restart time can be preset from 1 to 99 hours.
