Vigilus Cableless Underwater Surveillance Array

Overview

Originally conceived as a solution for marine life monitoring, Vigilus is a subsea acoustic surveillance array that collects, interprets, and acts on acoustic and environmental data. Vigilus can be deployed as a single node or as an array of acoustically-meshed nodes spread multiple kilometers apart from one another. Its compact and cableless design allows it to be deployed easily from small boats or covertly, even under ice, from a large autonomous underwater vehicle (AUV).

With an endurance of over one year, Vigilus provides persistent subsea monitoring in hard-to-reach locations without requiring significant infrastructure installation.


Array Overview

Vigilus nodes deployed on the seafloor are spaced multiple kilometers apart. The sensors connect acoustically to establish a “fence” or “array” for observation in a location, and work together intelligently to provide persistent surveillance underwater.

Each Vigilus node autonomously collects and processes acoustic and environmental sensor data in its area; the data collected can be pattern matched onboard to a library of sound sources. Vigilus can be programmed to automatically make decisions, based on the classification and confidence of the match, to pass on events, messages, and locations in near real-time between itself and other in-area assets, such as AUVs or topside communication equipment.

Benefits

Easy, Covert Deployment

Vigilus can monitor maritime choke points, including hard-to-reach areas like under ice or challenging topographical environments, for over one year without maintenance.

Battlespace Shaping

Vigilus can periodically send acoustic pings when dropped at key chokepoints, serving as a deterrent for unwanted vehicles entering the area.
 

Real-Time Monitoring

High bandwidth data can be transferred via a blue light modem when AUVs or other assets are nearby. When connected to central command via a shoreside gateway, events are passed over in near real-time, allowing for timely decision making without having to recover the node.
