Marins Series

Marins M7, first rank and submersible ships Inertial Navigation System

Military strategic grade INS

1 nautical mile per 12 / 24 / 72 hr 

Pure inertial performance

Marins Series is a family of state-of-the-art naval inertial navigation systems, designed to meet the demands of the navy for the highest performance INS.

Marins Series enables stealth autonomous navigation for submarines, providing very accurate heading, roll, pitch, speed and position. These products also uniquely adresse the need for advanced naval surface vessels, operating under severe GNSS-denied environment.

Marins Series includes three performance grades and is based on the iXblue FOG technology, proven for superior reliability and performance.

iXblue high-performance navigation systems are chosen by world leading navies.
