NAUTILUS

Naval Inertial Navigation Family

INS/GNSS Navigation and Stabilization System

The NAUTILUS family of strapdown Fiber Optic Gyro (FOG) Naval Inertial Navigation Systems (INS) is designed for performance scalability up to high-grade position accuracy and long endurance missions.

The proprietary ITAR-free FOG-based sensor technology coupled with advanced state estimation techniques based on Kalman Filter algorithm, provides the best-value solution for Gyrocompass, AHRS (Attitude Heading Reference Systems) and Positioning in an all-in-one maintenance-free product, compact, light and reliable.

Specifically aimed at marine navigation, NAUTILUS family is engineered to guarantee performance in severe environments, both with or without GNSS and Speed Log aiding, and to allow flexible and easy integration in retrofit programs and in new vessels’ installations.
