Maritime RLG INS(Dubhe-M1)


Designed for maritime navigation challenges, our optical strapdown INS integrates precision RLG/FOG gyroscopes with quartz accelerometers in a robust sensor assembly. The system's high-speed processing unit executes real-time strapdown computations, supporting multiple operational profiles from pure inertial to GNSS/velocity hybrid modes. This ensures reliable, continuous navigation data output for diverse marine platform requirements.
