Defense & Security

The CAT EYE XLR is a fixed day/night vision system with high performance extra-long-range observational capacity, challenging the world of infrared and previously-available nighttime identification capabilities for defense and security forces.

This system renders a 24/7 flux of video in FULL HD, providing even more pixels and increasingly more visibility than its field-proven CAT EYE predecessors. CAT EYE XLR provides crisp, natural vision in the visible spectrum from daylight to the dark of night, making it possible to identify a vehicle or vessel at up to 20 kilometers away in pitch black or conditions of low visibility. Its daytime range of vision is 40 kilometers when the system is mounted at an elevated position.

Range-gated active imaging is the mode allowing for target identification in the dark of night and this is a technology in which LERITY possesses true expertise; Active Imaging also provides improved quality of vision in rain, snow, fog, heavy pollution or even sandstorms. The CAT EYE XLR’s 200 W laser sources, illuminating the target with one thousand pulses of light per millisecond, are divided into two fields of illumination: narrow and ultra-narrow, to allow for precise target designation.

All the features of a ruggedized and modern surveillance camera (gyro-stabilized turret, telemetry, GPS, recording and playback on control screen…) make this technological jewel an unparalleled asset for coastal surveillance, border surveillance or perimeter surveillance, and for the protection of critical infrastructure (nuclear parks, oil facilities, and more).

Since the launch of the product line in 2015, CAT EYE vision systems have received very positive feedback from homeland security and military forces. They are the subject of extensive testing campaigns and have been integrated as security solutions in several countries including France. The development of the CAT EYE XLR is supported by the French Navy. It is compatible with various sensors (Radar, AIS...) and can be integrated with various C2 command systems.

HEMISPACE, a hemispheric optronic imaging system, is a state-of-the-art vision system designed by LERITY for the 360° detection, localization and tracking of UAVs. Composed of 12 very high-resolution cameras evenly distributed across a half-sphere structure, HEMISPACE ensures full-sky coverage and the rapid detection of any flying object including micro-UAVs measuring 30 cm × 30 cm. Each of the 12 cameras can detect and track up to 10 targets, for a total of 120 possible threats processed by HEMISPACE. This allows for effective surveillance against the topical threat of both single drones and drone swarms, increasingly used for hostile purposes.

Multiple HEMISPACE systems can be combined in a network for increased coverage of the detection zone (up to 6 km), interconnected either by a private and secure IP network or by wireless communication (secure 3G/4G/5G). This mesh of HEMISPACE makes it possible to triangulate data in order to measure the distance of the potential drone threats from the site under HEMISPACE protection.

HEMISPACE can be implemented both at night and during the day, including in glaring sun, rain, fog and other difficult environments thanks to its robust sensors and high-performing algorithms. Two modes, passive and active, allow the operator working at night to choose when to illuminate the sky around the system with HEMISPACE’s embedded light sources (emitting flashes of light lasting just tenths of a millisecond, in order to preserve stealth). The entire system can be illuminated or the illumination can be implemented by sector.

HEMISPACE is operable 24/7 with a command and restitution GUI (Graphic User Interface). The operator chooses to view an image of the target by clicking on the dots representing the target. The real-time visualization of the target allows for quick decision making in the face of potential danger.

HEMISPACE is transportable and can be quickly deployed. It can also be connected to other sensors or equipment, making up a global system in the fight against drones. HEMISPACE is suitable for the protection of military sites but also for the protection of civilian infrastructure such as airports, industrial facilities, power plants, sporting complexes and more.

ALSEAMAR designs and manufactures portable trajectography systems for devices moving under water, torpedoes or drones, under the GIB product line.

Consisting of a control unit and a set of buoys, they receive the signals transmitted by the acoustic transmitter mounted on the underwater device being tracked. The buoys measure distances and use a local radio network to periodically transmit their GPS position and the distances measured to a control unit installed on a support or land vehicle. This unit triangulates the positions of the underwater device and displays them on a map in real time and with great precision.

GIB portable trajectography systems are used by manufacturers in the naval sector to qualify their subsea machinery and by naval forces to train their crews and to intervene in the event of a stricken submarine in order to accurately locate it.

ALSEAMAR X-SUB buoys allow submarines to communicate with above the sea’s surface without raising a periscopic communications antenna. The submarine continues its course, undetectable at its operational depth.

The X-SUB buoy is a device released via the standard ejector (sippican). The buoy then rises to the surface and remains connected to the submarine by a wire connection.

The buoy acquires the GPS and the AIS positions, which are transmitted to the submarine. The GPS and the AIS positions are visible on board the submarine on a designated operating unit screen.

Once the wire connection is broken, the buoy automatically scuttles and sinks.

ALSEAMAR designs and manufactures subsea propulsion vehicles used to transport frogmen (2 to 6 combat divers— depending on the type of vehicle) during special operations: expansion of their scope of operations, strategic target attacks on land and at sea, infiltration or exfiltration of commando units, intelligence, surveillance and reconnaissance missions, and maritime counter-terrorism.

These antennas and multi-couplers can be used to create a subsystem of antennas for surface vessels that incorporate the most stringent radar cross-section reduction requirements.

ALSEAMAR designs, manufactures and operates autonomous, high-endurance subsea drones: the SeaExplorer gliders.

Designed to collect data over large areas (thousands of kilometers), over long periods (months) and at great depths (up to 1,000 m), SeaExplorer gliders are propelled by buoyancy variation. SeaExplorer vehicles silently glide along the water column, collecting physical, chemical, biological and/or acoustic data, depending on the sensors installed. Their major added value lies in their low procurement and operating costs compared to the vessels or other means traditionally used for the same type of mission.

SeaExplorer gliders are easy to operate and can be deployed and recovered by a smaller crew, using small boats in coastal waters. Remotely controlled via satellite communication, they receive orders from the control PC at an ALSEAMAR site or at another designated site and transmit navigation information and collected data to land.

SeaExplorers are used by scientists and oceanographers, by environmental agencies responsible for protecting seas and oceans, by operators in the oil sector and by navies.

ALSEAMAR operates Gliders for its clients on a  24/7 basis and in every sea of the world.

The MURENE subsea light vehicles are a new grade of subsea diver propulsion systems. They have been designed to provide the best ergonomics and performance standards for combat swimmers.
