Proven in a wide range of industries in a variety of challenging deployments around the world, our products are ideal for naval and defense forces and OEMs looking to adopt cutting-edge solutions that deliver the utmost in performance for mission-critical underwater operations.

All our products are fully software-configurable, doing away with the need to open them in the field and eliminating risks of contamination and water ingress.

Imaging Sonars

Featuring the world’s most compact imaging sonar, the ISS360 range provides ROVs, AUVs and other subsea naval vehicles with real-time 360° high-resolution acoustic imaging capabilities. Utilizing a mechanically-scanned broadband composite transducer and advanced CHIRP acoustics (Compressed High Intensity Radar Pulse), the sonars are ideal for precision navigation,  obstacle avoidance, and target identification for applications such as ISR (intelligence, surveillance and reconnaissance) or MCM (mine countermeasures).

The ISS360 imaging sonars are rated to depths of 6000 meters and the ISS360HD also provides enhanced angular resolution and range. Both variants feature a rugged titanium housing and can be equipped with an optional pitch and roll measurement capability based on MEMS inertial sensors.

Profiling Sonar

The high-performance mechanically-scanned ISP360 profiling sonar offers cutting-edge subsea measurement capabilities, delivering unparalleled accuracy for applications such as 3D seabed and terrain mapping, structural profiling, and UXO and target scanning.

Housed in a rugged titanium enclosure and depth rated to 4000 meters, the versatile ISP360 offers a frequency range of 650kHz to 1.25MHz, and supports Continuous Wave (CW), Compressed High-Intensity Radar Pulse (CHIRP), and the proprietary Impact Subsea Signalling Scheme (IS3) for superior signal clarity and reliability.

Altimeters

Impact Subsea altimeters provide millimeter-accurate underwater distance measurements in a compact, durable form. Designed for seamless integration, they are available in housings rated to 11,000 meters and support forward-looking or right-angled configurations, with digital and analog interfaces suited to a wide range of subsea defense applications.

These systems offer optional Echogram capability for detailed sonar backscatter data at up to 2,000 samples per ping, as well as an integrated Attitude and Heading Reference System (AHRS) for reliable heading, pitch, and roll data.

Depth Sensors

The ISD4000 is a survey-grade depth and temperature sensor that provides high-accuracy data for submarines and underwater vehicles, naval sensors and equipment, and tactical environmental intelligence applications. Depth data can be provided to ±0.01% or 0.005% full scale accuracy, with multiple options available for range. Temperature data can be provided to 0.1 or 0.05 degrees C accuracy.

The sensor can also be fitted with a MEMS-based AHRS for heading, pitch and roll measurement.

Attitude & Heading Reference System

The ISM3D is an advanced AHRS that provides high-accuracy real-time orientation and heading information for stabilization and control of naval equipment and manned/unmanned underwater vehicles, as well as for navigation aiding in underwater GNSS-denied environments. It delivers heading data with accuracy to ±1° of local magnetic north, and pitch and roll data to ±0.07° accuracy. In environments with large amounts of ferrous metals or other magnetic disturbances, the magnetometers can be deactivated, and heading accuracy can be boosted thanks to a built-in soft and hard iron calibration feature.

The underwater AHRS can be provided in an acetal housing depth-rated to 1000 meters, a rugged 6000 meter-rated titanium housing, or as an OEM system.

Flooded Member Detection System

The ISFMD flooded member detection system is a diver- or ROV-deployed solution based entirely on high-accuracy ultrasonic technology, doing away with the logistical and safety issues posed by radiation-based systems. The system is ideal for rapid integrity assessment, inspection and maintenance, and damage investigation of subsea structures, and automatically adjusts acoustic settings to ensure that both small and large members can be tested accurately and repeatedly. An optional depth sensor can be integrated to automatically record the depth of each check point.

The system is available with a 100 or 200 meter cable reel, and includes a topside box that enables easy plug-and-play connection for all components. Configuration, data reading and visualization, and automatic reporting are all provided by our powerful seaView software.
