Subsea Sentinel

Subsea Sentinel Overview

A cableless array of long-endurance, autonomous seabed sensors collects and communicates critical real-time ocean information. The node is configurable with custom sensor packages, ranging from acoustics for military detection to marine mammal detection and environmental sensing.

Advanced Detection and Analysis

The system monitors, detects, and characterizes mobile objects, both anthropogenic and natural, using advanced in-situ processing built on proven technology. This enables real-time analysis, classification, and response to detected objects, enhancing situational awareness and security.

Versatile Deployment and Communication

The system offers a 10-kilometer range between nodes for sensing and inter-node communication. It can be deployed by vessel or large AUV and boasts a one-year operating life. Sensor expansion options, including LBL, and a CTD sensor are available, offering versatility and adaptability.

Advanced Underwater Surveillance with Subsea Sentinel

These nodes offer a cutting-edge solution for underwater surveillance and security. Deployed across large areas, these autonomous nodes form intelligent networks that detect, classify, and track underwater sound sources. With their long endurance and low-power operation, They provide persistent monitoring in remote and challenging environments. By integrating seamlessly with underwater systems, such as AUVs, our Subsea Sentinel enables comprehensive situational awareness and timely response to emerging threats.
