Marine-Grade Strapdown Inertial Navigation System

The Core Assurance of Maritime Navigation Reliability

In modern maritime operations, the growing demand for intelligence, high precision, and high reliability has made Inertial Navigation Systems (INS) a critical foundation of shipborne navigation. Especially in complex sea conditions, ocean-going operations, and GNSS-challenged environments, INS provides stable and reliable positioning, navigation, and attitude information through its fully autonomous operation, independence from external signals, and continuous output.

High-Performance Marine-Grade Inertial Navigation Solution

Our marine-grade strapdown inertial navigation system integrates advanced Ring Laser Gyroscopes (RLG) or Fiber Optic Gyroscopes (FOG) with high-precision quartz accelerometers to deliver outstanding performance. Powered by a high-performance computing core and precision strapdown algorithms, the system continuously provides accurate heading, attitude (roll, pitch, yaw), and motion data, meeting the stringent requirements of diverse maritime applications.

Multi-Mode Integration for Continuous Navigation

Unlike navigation solutions that rely solely on GNSS, this system is immune to signal blockage, interference, or short-term outages. When satellite signals degrade or become unavailable, the INS can maintain high-accuracy output for a defined period.
Supporting pure inertial, GNSS-aided, and velocity-aided modes, the system can be seamlessly integrated with gyrocompasses, speed logs, and other onboard sensors to form a high-performance integrated navigation solution, significantly enhancing safety and continuity in coastal waters, narrow channels, severe weather conditions, and open-sea operations.

Designed for Maritime and Offshore Applications

The system is well suited for a wide range of maritime and offshore applications, including:

• Dynamic Positioning (DP) vessels and offshore platforms

• Hydrographic survey and marine mapping vessels

• Unmanned Surface Vessels (USVs) and specialized workboats

By delivering high-rate, stable, and continuous navigation and attitude data, the system effectively supports precise vessel control and complex offshore operations.
