TG-5000

Gyrocompass · Position & Heading

Class-certified type (DNV register) · technical data sheet not yet verified

Tokyo Keiki TG-5000 is a marine gyrocompass or electronic heading-reference unit. It is normally installed in the bridge electronics or navigation equipment space with heading outputs distributed to steering and navigation consumers. Its primary purpose is to provide a stabilized true-heading reference for navigation, radar, ECDIS, autopilot and other bridge systems. Compared with a magnetic compass, a gyrocompass does not depend on the Earth's magnetic field and requires electrical power, sensors and internal control electronics. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

Service

Service notes.

What our service work and the manufacturer documentation say about keeping this model running.

Compare master and repeater headings with independent references and check alarm history, power supply, distribution interfaces and settling behaviour after restart. Verify heading delivery to all critical consumers. Any internal calibration or alignment should follow approved service procedures. Refer to manufacturer documentation for the exact figure for permissible errors and adjustment criteria.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
