INT-D-M48 High Precision Velocity Integrated Marine Inertial Navigation System Laser Gyro


Maritime RLG INS

 

The long-endurance, high-precision marine optical INS employs laser/FOG gyros and quartz flexure accelerometers as core sensors. Utilizing a "strapdown + modulation" technical architecture with advanced navigation algorithms, it delivers real-time navigation solutions. Offering multiple operational modes (pure inertial, GNSS-aided, and velocity-integrated), the system provides enhanced full-state navigation parameters to meet various marine platform requirements.
