An Inertial Navigation System (INS) is at the heart of a vessel’s navigation. It provides key position and time data without having to rely on easily disrupted GNSS signals. Such a critical role requires both high-performance, and unfaltering reliability.

iXblue is the European leader in naval navigation systems and equips over 40 navies worldwide. Our wide range of sensors and systems are designed to address the requirements of the full spectrum of naval platforms, from smaller coastal and support vessels to aircraft carriers, including main surface combatants and submarines. All of our INS are maintenance and ITAR-free.

Unmatched Performance

The performance of a fiber-optic gyroscope can be changed by altering the length and diameter of its coil, making it adaptable to a wide range of performance needs. Performance can further be increased by pushing back the technological limits of the optical components that are used within the FOG gyroscope.

Because iXblue has complete mastery over all the components that are integrated into its systems, from its own optical fiber and components, to its accelerometers and algorithms, the company can push the limits of the FOG technology to have it reach new peaks of performance.

Powered by FOG

The FOG (Fiber-Optic Gyroscope) is the result of more than 30 years of research and development and is today considered to be the best gyroscope in the world: its performance is deemed genuinely unlimited.

Based on the Sagnac effect, FOGs are passive systems that use light to calculate motion. Rotations movements are measured by sending identical laser beams, in opposite directions, through a long fiber-optic coil.The laser beam travelling against the direction of rotation experiences a slightly shorter path delay than the other beam. Measuring the phase shift between the two beams reveals changes in orientation. Objects being free to rotate in three dimensions, iXblue’s Fiber-optic based inertial navigation systems contains three FOG gyroscopes, measuring rotations on those three different axes.

Outstanding Reliability

Fiber-Optic Gyroscopes are truly solid-state passive systems. Indeed, the FOG technology does not involve any movement of mechanical parts causing dithers, vibrations, frictions and resulting in parts’ weariness and noise. This ensures many benefits for the user: acoustic stealth, robustness of the system (Power-on and Forget), cost-effectiveness and the lowest cost-of-ownership on the market

Operating as a single component and relying only on light motion, FOGs are resistant to external disruptions such as shocks, extreme temperatures, magnetism or vibrations. This is why FOGs equip systems operating in extreme environments or expecting high resistance from their sensors: satellites, strategic submarines, long-range artillery, extreme deep-water robots and vehicles.

Complete Mastery of Technology Through Vertical Integration

iXblue has end-to-end control of its value chain, from the design work carried out in its engineering offices through to manufacturing in the company’s own production facilities. Its control over the performance of its products and its capacity to adapt are guarantees of quality and excellence.
