Tokimec TG-8000 Gyrocompass

Overview

The Tokimec TG-8000, also known in some markets as Simrad GC-80, is a high-precision gyrocompass system designed for IMO-compliant ships. Backed by Tokyo Keiki’s extensive legacy—with over 8,000 installations—the TG-8000 offers exceptional reliability, long service life, and advanced integration capabilities.


Key Features

  • Proven Track Record
    Built upon decades of expertise, the TG-8000 is renowned for its stability and durability in demanding maritime applications.

  • Compact Two-Unit Design
    The system comprises a master compass and a separate control unit—offering efficient use of space on modern vessels.

  • Low Maintenance & Extended Service Life
    With no need for maintenance fluids, the TG-8000 significantly reduces upkeep costs and downtime.

  • Versatile Output Interfaces
    Supports a wide range of heading outputs, including NMEA 0183, fast serial formats compliant with IEC 61162-2, analog rate-of-turn, and dry contact signals.

  • Fast Heading Response
    Designed to support dynamic navigation requirements with high follow-up rates and compatibility with external heading sensors.

  • Optimized for Dual-Gyro and Space-Conscious Installations
    The modular design eases integration into dual-gyro setups, reducing installation complexity and footprint.

  • Automatic and Alarm Functions
    Features include automatic timer startup and Bridge Alert Management (BAMS) support to help maintain navigational safety.


Applications & Benefits

  • Commercial, Naval, and Offshore Vessels
    Ideal for standard ship navigation, including those requiring integration into Integrated Bridge Systems.

  • High-Speed Craft Compatibility
    The TG-8500 variant is specifically adapted for vessels operating at speeds up to 70 knots, while maintaining similar reliability.

  • Efficient for Upgrades and Refits
    The compact, low-maintenance design makes the TG-8000 well-suited for both new builds and modernizing existing gyro systems.
