Description
The Highlander HLD-GC 100 is an all-solid-state 3-axis Fiber Optic Gyrocompass (FOG) with sub-0.2 degree secant latitude accuracy, settling time under 15 minutes, zero annual overhaul requirements, and MED Wheelmark certification.
System Overview & Engineering Architecture
The Highlander HLD-GC 100 FOG Gyrocompass represents a next-generation digital marine navigation solution developed jointly by Highlander and CSIC 455 Factory. Designed in accordance with the latest IMO specifications, it integrates over a decade of operational shipboard experience into a robust and precise heading reference system.
As the first domestically produced gyrocompass compliant with ISO 8728-1997, the HLD-GC 100 also holds CCS type approval in China. It meets the requirements outlined in Chapter 6 of IACS UR E26 Rev.1 and Section 1.4 of the CCS Guidelines for Ship Cybersecurity (2025), ensuring suitability for modern intelligent and cybersecurity-compliant maritime operations.
The system employs a Fiber Optic Gyro (FOG) as its core sensing element, enabling high stability, low maintenance, and extended service life. The modular architecture allows flexible deployment across different vessel types and configurations.
Core Features & Operational Advantages
Full Digital Design
The HLD-GC 100 utilizes digital servo control, achieving a heading accuracy of ±0.25° × secΦ. All input/output interfaces conform to the IEC 61162-1 standard, supporting plug-and-play connectivity with ECDIS, autopilots, and integrated bridge systems.
Short Settling Time
Equipped with an inertial navigation device combination, the master gyrocompass automatically presets its initial position to local magnetic north upon power-on. This reduces the static settling time to less than 2.5 hours, minimizing downtime during vessel startup.
High Dynamic Accuracy
A unique vibration-damping design and dynamic roll/pitch compensation technology enhance system performance under adverse sea conditions. The dynamic accuracy error remains within ±1.0° × secΦ, ensuring reliable heading output even in heavy weather.
Multiple Application Modes
The system supports three application configurations:
- Compact Mode: Minimal footprint for smaller vessels.
- Standard Mode: Balanced performance and expandability.
- Redundant Mode: Dual-independent systems for critical navigation safety.
- IMO Standards: Compliant with the latest IMO regulations for marine navigation equipment.
- IEC 60945: General standard for maritime navigation and radio communication equipment.
- ISO 8728-1997: Special standard for marine gyrocompasses.
- IACS UR E26 Rev.1: Chapter 6 compliance for ship cybersecurity.
- CCS Type Approval: Certified by the China Classification Society.
- No Annual Onboard Inspection Required: Unlike traditional mechanical gyrocompasses, the FOG-based system does not require yearly servicing.
- Gyrosphere Replacement Interval: The FOG sensor module has a rated lifespan of 20,000 hours, after which it should be replaced.
- Software-Based Calibration: Baseline deviations are corrected digitally, reducing the need for physical recalibration.
- Spare Parts Supply: Genuine FOG modules, distribution units, operation panels, and repeater compasses.
- Installation & Commissioning Services: Available at major ports including Jebel Ali, Khalifa Port, and Port of Fujairah.
- Maintenance Contracts: Tailored SLAs covering preventive maintenance, fault diagnostics, and emergency response.
