Marine Gyrocompass HLD-GC 100-Highlander

Product Overview

The HLD-GC 100 type marine gyrocompass is a newly developed digital marine navigation product jointly developed by Hyland and CSIC 455 Factory in strict accordance with the latest IMO specifications, drawing on more than ten years of practical ship application experience of previous products. As the first domestically produced gyrocompass compliant with the international standard ISO 8728-1997 and certified with CCS type approval in China, this product also meets the relevant requirements specified in Chapter 6 of IACS UR E26 Rev.1 and Section 1.4 of the CCS Guidelines for Ship Cybersecurity (2025), making it applicable to the navigation, intelligent and cybersecurity compliance requirements of various types of ships.

Product Features

Compliant with international standards and regulations

The HLD-GC 100 Gyrocompass System fully complies with the IEC 60945 general standard and the ISO 8728-1997 special standard.

Fully digital design

Adopting digital servo control, the heading accuracy reaches ±0.25° × secΦ. All input/output interfaces comply with the IEC 61162-1 standard. Latitude and speed errors are automatically compensated.

Short settling time

Equipped with an inertial navigation device combination, the master gyrocompass automatically presets its initial start-up position to the local magnetic north upon power-on, significantly reducing the settling time. The static settling time is less than 2.5 hours.

High dynamic accuracy

Adopting a unique vibration-damping design and dynamic roll/pitch compensation technology, the dynamic performance of the gyrocompass system is enhanced, with a dynamic accuracy error of no more than ±1° × secΦ.

Multiple application modes

Adopting a modular design, various components can be flexibly combined. The application types are divided into: Compact, Standard, and Redundant.

Easy installation and maintenance

The master gyrocompass features a compact size (380×310×452 mm) and light weight (24 kg). Installation baseline deviations can be corrected via software, reducing installation requirements. No annual onboard inspection is needed; only the gyrosphere needs to be replaced before the master gyrocompass reaches its service life.
