Sonars
The SeapiX-FLS Series is a range of scalable 3D multi-beam Forward Looking Sonars that are particularly suited for obstacle avoidance, real-time seabed mapping and rapid environmental assessment (REA) applications.
Offering obstacle detection from the seabed to the surface, they offer unmatched situational awareness for increased safety of navigation.
Safer navigation through unmatched environmental awareness
A unique design for real-time obstacle detection
The SeapiX-FLS Series, embedding its own Inertial Measurement Unit (IMU), provides a clear and precisely georeferenced picture of the surrounding environment. Thanks to its unique, three-dimensional coverage of the water column and bathymetric profile, the SeapiX-FLS Series offers extremely accurate, real-time obstacle detection, as well as object analysis (based on position and kinematic, target strength index, acoustic measurements, etc.). This ensures vessels safe navigation.
Obstacle detection from the surface to the seabed
Thanks to its innovative electronically steerable Mils Cross antennas, the SeapiX-FLS Series provides unrivaled coverage of the entire water column, from surface to sea bottom. Each detection is then mapped in real-time within the surrounding environment, and autonomously provided to external systems. It can also be displayed in 2D/3D within Exail’s operator oriented MMI. This ultimately provides crews with a clear picture of what lies ahead, both at the surface and subsea.

Low Target Strength object in water column (-25dB)

Water column coverage from surface to seabed
Having a long detection range and high accuracy is one thing. But SeapiX-FLS goes even further by providing a detailed scan of everything within its range using four different types of swaths. It can even track identified targets for confirmation.
A fully autonomous detection process
No need to be a sonar expert to operate SeapiX-FLS. Fully dynamic, the detection, tracking, classification, and avoidance capabilities can run in the background in full autonomy. Should operators need it, the process can also be set manually, case by case, allowing for maximum flexibility.
An intuitive and efficient User Interface
Providing real-time obstacle detection probability map
The SeapiX-FLS Series can generate a real-time obstacle detection probability map. This information is crucial for crew decision making, allowing them to adapt their speed according to their underwater environment. This provides increased navigation safety for both for the crew and the platform.
One single interface for efficient multiple FLS operations
Increased detection coverage can be reached by combining multiple SeapiX-FLS on the same vessel, with no further hassle for the operator thanks to the SeapiX-FLS user-friendly MMI. This MMI can centralize and simultaneously display information gathered by the multiple SeapiX sonars.
A FLS for all vessels and drones
SeapiX-FLS mounted on DriX USV's gondola
The SeapiX-FLS Series offers a scalable solution that can be mounted on all crewed and uncrewed surface and subsea vehicles. It can be integrated on:
Hulls
- Hoisting systems
- Gondolas
Specific integration can be discussed between integrators, shipbuilders and Exail.
The SeapiX-FLS Series can also be installed on fixed platforms (buoys, tripods on the seabed…) for port and subsea infrastructure monitoring operations.
