Applications of the Tokyo Keiki TG-8000 on Ships is a specialized navigation device used to provide heading – ship ’s directionaccurate heading data for the ship ’s maritime system. The device belongs to Tokyo Keiki ’sTG-8000/8500 Gyrocompass series, where TG-8000 is designed for IMO standard vessels, while TG-8500 is developed for high-speed vessel applications.

In the cockpit system, heading data from the gyrocompass is typically transmitted to radar, ARPA, ECDIS, autopilot, AIS, VDR, repeater compass, and other navigation equipment. Compared to magnetic compasses, gyrocompasses do not directly depend on the ship ’s magnetic field, providing more stable true heading in professional maritime environments.

High reliability, inherited from the widely used TG series

TG-8000/8500 was developed by Tokyo Keiki based on the previous TG series, a product line that has been installed on over 8,000 vessels. The device maintains important advantages such as high reliability, good follow-up capability, and communication capabilities with various onboard maritime equipment.

This makes Tokyo Keiki TG-8000 a suitable choice for vessels requiring a stable gyrocompass system that can operate for long periods and integrate into various cockpit configurations.

Designed for standard IMO vessels

TG-8000 designed for IMO standard vessels. Some technical sources state that TG-8000 is for IMO regulated vessels, meeting IMO A.424(XI)and in appropriate configurations. These technologies help improve the quality of positioning data when the operating area has corresponding augmented signal support.ISO 8728, while TG-8500 is oriented towards high-speed craft according to IMO A.821(19)and in appropriate configurations. These technologies help improve the quality of positioning data when the operating area has corresponding augmented signal support.ISO 16328 HSC.

. Therefore, when selecting equipment, users need to clearly distinguish between TG-8000and in appropriate configurations. These technologies help improve the quality of positioning data when the operating area has corresponding augmented signal support.TG-8500 to match the vessel type, operating speed, and classification requirements.

Fast follow-up speed, up to 75°/s

One of the highlights of the Tokyo Keiki TG-8000/8500 series is its fast steering follow-up speed, with a maximum follow-up rate of 75°/s. This feature allows the system to respond quickly to changes in ship heading, providing excellent support for navigation, autopilot, and devices that require continuously updated heading data.

High follow-up capability is particularly useful in maneuvering, turning, docking/undocking, or when the ship operates in areas with heavy traffic density.

High-speed serial data output per IEC 61162-2

TG-8000 Gyrocompasssupports high-speed serial data output according to the standardIEC 61162-1This is a high-speed marine data communication standard, enabling the gyrocompass to transmit heading data to marine electronic devices that require stable and accurate heading signals.

The standard data output capability allows the TG-8000 to be easily integrated with radar, ECDIS, autopilot, heading display systems, central control systems, and other marine equipment.

Supports communication with external heading sensors

Tokyo Keiki TG-8000/8500 can communicate withexternal heading sensorThis feature enhances system flexibility in configurations with multiple heading sources or when integrating with existing shipboard heading/backup systems.

For ships requiring high safety, an additional external heading source can provide backup, cross-check data, and increase flexibility in system design.

Optimized for dual gyro systems, saving installation space

TG-8000/8500 supportsdual gyro systemconfiguration with a minimum number of components, saving space and reducing installation costs. This is a significant advantage for ships with limited equipment room space or those requiring a redundant configuration while optimizing equipment layout.

Dual gyro configurations are often used on ships requiring high availability of heading data, helping to reduce the risk of losing heading information if one unit fails.

Convenient Startup Timer function

Startup-timer function is a feature equipped on the TG-8000/8500 series. This feature supports setting the system startup time, allowing the gyrocompass to be ready before the ship begins its voyage.

In practice, the gyrocompass requires stabilization time before providing accurate heading. Therefore, the startup timer function helps optimize pre-voyage preparations.
