Marine Fiber-Optic Inertial Navigation System (FOG-INS) for High-Precision Maritime Guidance & Positioning

Product Description
The Marine Fiber-Optic Inertial Navigation System (FOG-INS) uses a fiber-optic gyroscope (FOG) and a quartz accelerometer as its primary sensing elements.
With strapdown inertial navigation technology and real-time computation algorithms, the system provides high-precision navigation outputs under continuous maritime operation.

It supports multiple operation modes, including standalone inertial navigation and FOG/GNSS integrated navigation, ensuring reliable performance even in GNSS-limited or offshore environments.
Real-time outputs include heading, roll, pitch, velocity, and position, enabling stable navigation control for marine platforms.

Advantages

• ✓ High-Performance FOG Sensor Architecture
  Low drift, high stability, and long-term accuracy for continuous marine use.
• ✓ GNSS + Inertial Hybrid Navigation
  Maintains situational navigation even with GNSS blockages or outages.
• ✓ Real-Time Navigation Data Output
  Supports vessel control, dynamic positioning, and stabilization systems.
• ✓ Compact Strapdown Design
  Suitable for ships, surface vehicles, and complex maritime payloads.
• ✓ Reliable Marine Operation
  Resistant to vibration, humidity, temperature changes, and long-duration motion.
