Maritime FOG INS – Military-Grade Precision Navigation for Modern Vessels

The Maritime FOG INS is a rugged, strapdown inertial navigation system (INS) designed for the most demanding maritime and naval environments. Utilizing fiber-optic gyroscopes (FOG) or ring laser gyroscopes (RLG) combined with high-precision quartz accelerometers, the system provides continuous, real-time navigation gyro outputs with unmatched accuracy in heading, roll, pitch, speed, and position—even in GNSS-denied or GPS-compromised scenarios.

Operational Modes & Features

• Autonomous inertial navigation for GPS-denied missions

• INS/GNSS integrated navigation using advanced Kalman filter algorithms

• Velocity-augmented navigation for dynamic marine maneuvers

• Attitude Heading Reference System (AHRS) capabilities

• High-speed real-time navigation processing for shipboard, USV, AUV, and offshore platforms

Key Advantages

• Reliable maritime INS performance under harsh conditions (shock, vibration, temperature extremes)

• High-precision fiber gyroscope and laser inertial navigation system accuracy

• Quick alignment and startup for mission-critical operations

• Flexible integration into existing inertial measurement systems and inertial navigation units

• Supports both commercial maritime and defense naval applications

Applications

• Shipboard navigation & gyrocompass replacement

• Tactical maritime guidance and platform stabilization

• Autonomous marine vehicles (USVs, AUVs)

• Offshore and research vessels

• Defense and naval operations requiring high-accuracy inertial guidance systems
