EXAIL

Marins Series enables stealth autonomous navigation for submarines and surface vessels. It provides very accurate heading, roll, pitch, speed and position, included in GNSS-denied environments. Marins Series is based on the Exail Fiber-Optic Gyroscope (FOG) technology and offers six grades of performance. This technology is proven for superior reliability and performance. Exail high-performance Inertial Navigation Systems (INS) are chosen by world leading navies.

• Autonomous navigation without GNSS, up to 1Nq en 72H
• Low cost of ownership
• Stealth: no radiated noise during operation
• Easy to set up and to operate
• Full range of INS performances

FOG technology : Exail is globally recognized for its pioneering work in high-performance Fiber Optic Gyroscope (FOG) technology. Gyroscopes are the core sensors of inertial navigation systems (INS), and FOGs, based on the Sagnac effect, deliver highly accurate rotation measurements using light waves in fiber-optic coils. This elegant design leverages the reciprocity of light propagation to achieve exceptional reliability and precision. Today, FOG technology stands as a leading solution for the naval industry.

Building on its 60 years of expertise in providing the highest-performance unmanned systems for missions at sea (USV, UUV) and in the air (UAV), Exail offers a complete, safe, fast and cost-effective UAV system for carrying out mine countermeasures missions at sea.

UMIS is a complete UAV system developed by Exail to monitor or secure large or complex offshore and coastal areas. This turnkey, modular solution includes a wide range of unmanned vehicles such as USVs, UUVs (AUVs, ROVs, MIDS), towed systems (sonars, scans) and UAVs. UMIS also integrates a complete UMISOFT software suite enabling simple, comprehensive management of the entire unmanned mission, from preparation, planning and supervision to data acquisition, processing, analysis and management.

UMIS is particularly well suited to naval and homeland protection operators engaged in battlefield, investigative or intervention missions at sea.

Netans Data Distribution Unit (DDU) is a central component of a vessel’s navigation system.

It collects and validates essential information—position, heading, speed, attitude, bathymetry, currents—and distributes it to onboard operational systems such as radars, combat systems, and navigation software. Designed to operate even in the event of cyberattacks, failures, or disruptions, Netans incorporates anomaly detection, event logging, and redundancy mechanisms. It therefore serves as a trusted link between sensors and operational applications, ensuring continuity and reliability of maritime operations.

Gecdis-W system is an electronic navigation software (WECDIS, used by military vessels) designed to meet the specific needs of naval forces. It displays on a single screen the vessel’s position, planned routes, areas to avoid, as well as real-time operational information such as the position of allied units and weather and sea conditions.

Compliant with NATO STANAG standards—standards that facilitate cooperation between allied navies—Gecdis-W enables efficient information sharing and optimal coordination during joint missions. By providing crews with a clear and reliable view of their environment, it helps them react quickly and make the right decisions, even in complex maritime conditions.
