Product Description
Product Description
The FOG INS (Merak-01) SMALL is a compact fiber-optic inertial navigation system designed for marine environments. It combines a high-performance Fiber-Optic Gyroscope (FOG) with a precision quartz accelerometer, using a modern strapdown architecture.
With integrated real-time navigation software, the system supports both GNSS-aided and pure inertial navigation modes, providing reliable navigation even when satellite signals are unavailable or jammed.
It delivers accurate heading, attitude, speed, and position data, making it ideal for small to medium-sized vessels.
Advantages
- High Accuracy & Low Drift: Optical gyroscope and quartz accelerometer ensure exceptional precision over long periods.
- GNSS-Denied Capability: Maintains navigation without GPS, crucial for remote or hostile environments.
- Compact & Energy Efficient: Perfect for vessels with limited space and power availability.
- Real-Time Software Integration: Outputs navigation parameters instantly, compatible with standard marine interfaces.
- Flexible Connectivity: NMEA and other common protocols for easy integration.
- Rugged Marine-Grade Design: Shock, vibration, humidity, and temperature-resistant.
- Suggested images: Accuracy comparison charts, software interface screenshots, internal hardware layout.
Application
- Commercial Surface Vessels: Merchant ships, workboats, and offshore support vessels.
- Autonomous Surface Vessels (ASVs): Precise navigation and station-keeping without GNSS.
- Underwater Platforms (ROVs/AUVs): Drift-optimized navigation in GNSS-denied underwater environments.
- Harbor & Coastal Operations: Accurate navigation near coasts or in dense traffic zones.
- Defense & Tactical Missions: Reliable navigation under GNSS spoofing or jamming.
- Suggested images: ASV on water, AUV underwater, coastal operations map overlay.
