The fiber-optic inertial navigation system (FOG INS) uses fiber-optic gyroscopes (FOG) and quartz accelerometers as its core sensors, delivering high-precision navigation for a wide range of platforms. Built on strapdown technology and enhanced with advanced real-time navigation algorithms, it continuously outputs accurate position, velocity, heading, and attitude data.

This system supports multiple operational modes, including integrated inertial/satellite navigation and standalone inertial navigation, providing flexible solutions for different mission requirements. Its robust design and high accuracy make it ideal for various vessel platforms, ensuring precise heading, roll, pitch, speed, and position information even in challenging environments.
