Autonomous Operations
Autonomous Acoustic Data Harvesting
The intelligent bridge between subsea assets and surface autonomy.
Solution Overview
As offshore operations transition to full autonomy, traditional data retrieval, relying on expensive telemetry buoys or manual diver intervention, has become a significant bottleneck.
Subnero’s Acoustic Data Harvesting Solution transforms any Unmanned Surface Vehicle (USV) into an intelligent data mule. By offloading the complexity of underwater connectivity to our smart modems, we enable seamless, end-to-end, high-speed data collection from seafloor assets with zero human-in-the-loop.
The Subnero Advantage
The Mission Workflow
Bridging the gap from seafloor to cloud in six seamless steps.
01. Easy Integration (Plug-and-Play)
Rapidly integrate Subnero technology into any USV platform. Seafloor assets are deployed using ready-to-go SWIS-integrated landers.
02. Autonomous Logging & Standby
Landers autonomously log sensor data (ADCP, CTD, etc.) while conserving power to maximize deployment longevity.
03. Proximity Activation
As the USV enters the deployment zone, it autonomously triggers the lander via an acoustic wake-up signal.
04. Smart Data Harvest
Modems establish an optimized link and manage the handshake, error correction, and adaptive modulation in real-time to download the relevant data.
05. Near Real-Time Relay
Harvested data is instantly uploaded to the cloud using high-speed satellite or 4G/LTE networks, delivering insights to your desktop.
06. Multi-Lander Scalability
The mission continues autonomously to the next lander, allowing one USV to harvest data from an entire underwater network in a single run.
