Product Description
The Merak-03 FOG INS is a high-precision fiber-optic inertial navigation system designed for maritime environments.
It integrates fiber-optic gyroscopes (FOG) with quartz accelerometers, utilizing strapdown inertial navigation technology combined with advanced real-time computational algorithms to deliver accurate navigation parameters.

The system supports both inertial/GNSS integrated navigation and pure inertial modes, ensuring reliable performance across multiple maritime operational profiles. It provides real-time outputs for heading, roll, pitch, velocity, and position, enabling stable and continuous navigation data even in environments where GNSS signals are intermittent or degraded.
