Eyra Acoustic
Array 8.0
Eight-hydrophone arrays with embedded PARse processing for autonomous platforms and custom installations.
Hear What Others Can’t
Most hydrophone arrays were designed for manned platforms. Eyra arrays are built for autonomous and distributed sensing, with embedded PARse processing running onboard. No operator in the loop. No shore-side dependency. Choose a proven rigid-mount configuration for uncrewed vehicles, or specify a custom geometry built to your mission.
Built for Autonomy. Flexible by Design
Embedded Processing
PARse acoustic signal processing runs onboard, performing beamforming, detection, and angle estimation. Noise goes in. Signal comes out.
Mission-Fit Geometry
Choose a rigid-mount array optimized for uncrewed platforms, or define a custom layout (horizontal line, circular, planar, or custom).
Multi-Array Fusion
Deploy multiple arrays across platforms. Data Fusion software localizes acoustic contacts in geo space using combined detections.
Platform Integration
Works across UUVs, USVs, fixed installations, and mission-specific platforms.
Choose the Configuration
Eyra 8.0 (Custom Geometry)
Eight-hydrophone system built to your specifications. You define the configuration and mounting approach. Vatn handles manufacturing, data acquisition, and embedded processing.
Eyra 5.1 (Rigid-Mount Standard)
Rigidly mounted beneath an uncrewed vehicle to resolve left-right ambiguity through geometry. Designed to operate while the platform holds position. No tow body. No shape estimation required.
The Numbers
What Ships With the Array
Where It Works
Harbor Defense
Persistent acoustic monitoring of ports and anchorages. Tailor coverage to port geometry and threat profiles.
Underwater Barrier Defense
Distributed arrays across USVs or fixed nodes for persistent area monitoring.
Sentry Operations
Unattended acoustic barrier defense across chokepoints and high-value areas.
Drug Interdiction
Detection of narco-submarines and semi-submersibles across patrol areas.
Experimental Data Collection / Sensor Development
Rapid prototyping and mission-driven array development for unique acoustic requirements.
Environmental Monitoring
Detection and tracking of marine mammals. Underwater noise monitoring for offshore wind and shipping compliance.
