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.
