Gyrocompass And Kalman Filter Universal Fiber-optic Gyro SINS

The FOG-based INS employs fiber-optic gyroscopes and quartz accelerometers in a strapdown configuration to achieve high-precision maritime navigation. With real-time inertial computation and GNSS-integrated options, the system ensures accurate heading, roll, pitch, speed, and position outputs for various ship platforms.

Its multi-mode operation—standalone inertial navigation, inertial/GNSS integrated navigation, and velocity-aided navigation—allows reliable performance in complex environments, including GNSS-degraded or GNSS-denied scenarios. This makes the system suitable for marine vessels, offshore platforms, and shipboard navigation applications requiring high-accuracy inertial positioning and attitude measurement.
