Description

The Maritime FOG Inertial Navigation System integrates high-precision fiber optic gyroscopes (FOG) or ring laser gyroscopes (RLG) with quartz flexure accelerometers as core inertial sensors. Using an optimized strapdown architecture and high-speed navigation algorithms, the system generates continuous real-time solutions for heading, attitude, velocity, and position.

The INS supports multiple operation modes, including standalone inertial navigation, GNSS-aided integrated navigation, and velocity-compensated modes. This flexibility enables the system to adapt to a variety of marine applications, providing full navigation outputs for both commercial and defense maritime platforms. Consistent performance is maintained even in GPS-denied or degraded maritime environments, ensuring mission safety and operational continuity.

Key AdvantagesINS

✔ High-stability FOG/RLG gyroscopes with low drift
✔ Quartz accelerometers for improved bias stability
✔ Robust strapdown computational architecture
✔ GNSS integration for hybrid navigation precision
✔ Reliable heading & attitude output in dynamic conditions
✔ Continuous real-time PVT (Position, Velocity, Time) data

Applications

Suitable for a wide range of maritime platforms, including:

• Hydrographic survey vessels
• Commercial ships & merchant fleets
• Offshore oil & energy platforms
• USV/AUV autonomous maritime systems
• Naval/Defense maritime operations
• Port & harbor navigation systems
