DriX, Gaps and FLS: iXblue Combined Solutions to Address Marine Threats

Speaker: Guillaume Eudeline - Global Business Developer Ships & Drones, iXblue


As technologies progress, the loss of human live becomes unbearable for the public opinion in a number of warfare domains. The cost of active and passive protecting measures of the service personal themselves comes at a very high price. The use of unmanned solutions backed on efficient detection and control systems somehow simplifies this difficult equation.

Three years ago, iXblue designed and built an offshore-going, 8 metre-long compact USV, deployable thanks to a well thought launch and recovery system, from most existing surface naval assets. This USV is called DriX. DriX sports an open software and payload architecture making it really versatile and – should the need arise – national.

This open and seasoned USV is the result of a strong integration which finds its roots in iXblue’s expertise in subsea positioning and acoustic detection. In those fields, iXblue provides state of the art solutions which bring a number of interesting capabilities to DriX.

First of all, the capability of tracking underwater AUVs thanks to a number of qualities and features, amongst which iXblue’s Ultra Short Base Line (USBL) Gaps stands out. The Gaps system is a compact all-in-one USBL with hemispherical tracking capability from extreme shallow water to open ocean, with now added bidirectional acoustic communication for control command and relocation of subsea assets. And to complete the picture, iXblue also designed a military grade sonar detection system, the FLS, providing safe navigation and underwater environment monitoring. Thanks to iXblue 3D Multi-Beam core technology developed in-house, and complete visualization into ECDIS environment, the FLS system is capable of Mine and Obstacle Avoidance, Intruder Detection and Rapid Environment assessment capacities.

All three solutions, DriX, Gaps and the FLS are in existence and sea-proven. This is what this paper will highlight.

Session 8B: Undersea

Technology: Navigation & Communication

Submarine Navigation Systems: Challenges and Solutions

Speaker: Yves Paturel - Senior Principal Engineer, iXblue


Submarine technologies have evolved so much in the last decades that a submarine does not need to surface as often as they did in the past. The consequence is that the requirement for navigation system onboard submarines becomes more and more stringent in terms of performance without position updates. If you add, on top of that, that any active navigation aiding sensor is forbidden for stealthiness sake, the challenge for the navigation system is to keep performance over extremely long periods of time by relying almost only on inertial sensors.

The paper will:

 - Explain why gyroscopes are the key elements for such a navigation systems,

 - Demonstrate that Fiber-Optic Gyroscope (FOG) technology is one, if not the only, technology to allow to design strapdown, non-redundant navigation systems fitting the requirements of one or several weeks of autonomous navigation,

 - Describe design and performance (demonstrated at sea) of the latest submarine navigation systems (the Marins series which include newcomers) designed by iXblue

 - Explain how this has been made possible through vertical integration allowing development in-house of key components (like optical fiber or Integrated Optics Circuit)
