For Unmanned Surface Vessels
Autonomous Subsea Data Operations
Turning the seabed into a connected node, for recurring, vessel light subsea data.
Rethinking Subsea Data
The Challenge
Retrieving seabed data has always meant sending a vessel, then waiting weeks for the results. For long term monitoring, that cost and delay no longer adds up.
The Solution
Subnero's Autonomous Subsea Data Operations platform turns any USV into an intelligent data harvester, relaying seabed sensor data to your endpoint over satellite or cellular. One communication layer, managed end to end, from seabed to shore.
A Smart, Integrated System
The Autonomous Subsea Data Operations platform is built as one system, not a stack of parts. Seabed landers carry your chosen sensors. A Subnero equipped USV transits the site and harvests data acoustically. Satellite or cellular backhaul carries it to the user’s cloud or operations center, where analytics turn it into decisions.
Subnero Acoustic Smart Modems sit at every seabed sensor node and on the USV, running edge intelligence that processes data where it is generated. Above the surface, Subnero’s software defined networking stack takes over, intelligently routing that data across available links such as satellite, cellular, or terrestrial, all the way to the user’s endpoint.
One communication layer, spanning the entire path from seabed to shore.
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 the right information to your endpoint.
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.
Core Operational Advantages
One system, end to end
Seabed sensors, USV, backhaul, and user endpoint, all connected through a single Subnero communication layer.
Intelligence at the edge
Subnero Acoustic Smart Modems process data where it is generated, so what reaches you is information, not noise.
Software defined, link agnostic
Subnero’s networking stack intelligently routes data across satellite, cellular, or terrestrial links, all the way to your endpoint.
Reduced reliance on recovery vessels
Replaces routine vessel mobilization with recurring autonomous USV missions, cutting day rate, fuel, and crew costs from every campaign.
Scalable underwater networks
One mission, many landers, one site wide dataset.
USV agnostic by design
Integrate with the surface platform of your choice. No lock in to a single vessel ecosystem.

Working With Collaborators
Subnero collaborates with leading USV operators, sensor manufacturers, and survey companies to bring Autonomous Subsea Data Operations to programs worldwide. Whether you operate your own USV fleet, work with a vessel provider, or are evaluating a new deployment, the platform is designed to integrate cleanly into your existing operations.
HydroSurv
Featured Collaboration
Subnero is collaborating with HydroSurv, a UK based designer and operator of battery electric and battery hybrid uncrewed surface vessels purpose built for the global survey industry. Together, the two companies are demonstrating a complete operational offering for persistent subsea monitoring.
