SEAEXPLORER 1000-M CONOPS

Concepts of Operations for SEAEXPLORER Defense and Security Underwater Glider

Acoustic intelligence - ACOUSTINT

Stealth collection of acoustic signatures in remote strategic locations

Payload options:

AURIS : recording and in-situ detection and alert with ability to identify navigation direction
PORPOISE: long-term recording

Concept of Operations

Stealth long-distance navigation in strategic areas (ports, naval bases)
Navigation without propellers in deep waters
Final approach with stealth propellers in very shallow waters
Bottom-landing mode for long duration signature recording
Recovery of glider and collected data outside of the recording zone
Analysis of recordings by intelligence services

Stealth System

Hybrid navigation without propellers or with stealth propellers in very shallow waters
Surface communication with an antenna having a very low radar and visual signature
Acoustic recording landed on the seafloor

Autonomous Platform

Range : ability to reach a target up to 1000km away and return autonomously
Recording for up to 2 months in bottom landing mode (with single channel) once the target has been reached
Easy to deploy from any platform
Supervision and piloting from shore

High-Quality and Reliable Data

Timestamping
Outstanding signal-to-noise ratio
Wide band frequency range

Passive Acoustic Monitoring - PAM

Stealth persistant detection of acoustic threats

Payload: recording and in-situ detection and alert with ability to identify navigation direction

Concept of Operations

Stealth deployment of the acoustic barrier over long distances
Persistent and movable acoustic barrier
Quick and easy barrier deployment
On-board detection of acoustic anomalies and periodic transmission of collected data
Positioning and tracking of threats

Stealth System

Hybrid navigation without propellers or with stealth propellers in very shallow waters
Surface communication with an antenna having a very low radar and visual signature
Bottom-landing and water column drifting capabilities

Autonomous Platform
