A leading navy has selected Exail to provide inertial navigation systems for its fleet of uncrewed surface vessels (USVs). The order, which includes systems from Exail's Marins range, is worth tens of millions of euros and represents one of the largest navigation systems orders ever received by Exail.

Navies are increasingly moving towards fleets where crewed and uncrewed vessels operate alongside one another. Deploying these autonomous platforms at scale places greater demands on the performance and reliability of navigation systems. The Marins range, Exail's highest-performance range of inertial navigation systems, is designed to meet these requirements, against a geopolitical backdrop notably marked by the increasing prevalence of GPS jamming and spoofing.

This order strengthens Exail's position in the fast-growing market for navigation systems for uncrewed surface vessels, leveraging its dual expertise in navigation systems and autonomous maritime robotics. The Group already holds a leading position in navigation for underwater vehicles, with its technologies equipping nearly 80% of AUVs and ROVs[1] worldwide. The markets for autonomous surface and underwater vehicles are both expanding rapidly, driven by applications in both defense and civilian sectors.
