Solus-LR Autonomous Underwater Vehicle

Quick Information

Solus-LR is a long-range hydrogen fuel cell powered Autonomous Underwater Vehicle (AUV) with an operational range greater than 2000 km.

Designed for port-to-port missions, Solus-LR provides a persistent subsea capability supporting ASW, ISR & MCM missions in addition to traditional subsea survey and inspection.

Used by the following organizations:

 
 

Design Highlights

Long Range

With a base range of 2000 km, the Solus-LR’s endurance enables port to port missions. This range can be further upgraded to over 4000 km for travelling even more impressive distances.

High Energy Density

A high-pressure Hydrogen and Oxygen fuel cell with a Li-Ion battery enables hybrid operation, allowing for the Solus-LR to complete multi-month submerged missions.

PERSISTENCE

Our patented suction anchor enables the vehicle to hold station at a surveillance location in a low power, quiet state for weeks or months - a feature unique to the Solus-LR.


Applications

Solus-LR’s architecture is inherently modular and flexible; the vehicle design can be customized to meet specific mission objectives.

Port to Port Missions

Solus-LR can be launched and recovered from boat ramps and docks, eliminating the need for vessels and saving your company money on expensive ship time. When powered by Solus-LR’s fuel cell, the AUV can travel long distances from one port to another.

Surface and subsurface surveillance

When at anchor, Solus-LR can operate in a quiet mode with the fuel cell shut down over long periods of time. With minimal acoustic emissions, Solus-LR is able to hold station in currents up to 2 m/s, covertly listen for a range of targets, and communicate back to base if a defined signature is observed.

Deployment and Recovery of payload packages

Solus-LR can be loaded with a payload package to be deployed from its bay doors. A variable buoyancy engine is used to offset the mass of the payload when deployed. The payload can be recovered by Solus-LR at a later time.

Geophysical Survey

Solus-LR is capable of surveying subsea areas and terrain using its sidescan sonar and magnetometer. A bathymetric chart of the target area can be generated using multibeam sonar, and analyzed for terrain features, slope angles and surface roughness.

Anti-Submarine Warfare

Solus-LR can be used to safely deploy anti-submarine warfare (ASW) barriers using a towed array. If a defined signature is observed during a mission, Solus-LR can communicate to headquarters and switch to an active mode to further locate the target.

Benefits

Longest-endurance survey AUV

Solus-LR’s novel suction anchor and fuel cell enables Solus-LR to hold station at a surveillance location in a low-power state for multiple months.

Powered by clean technology

The fuel cell is powered by hydrogen: a high-efficiency green fuel. The vehicle can operate without a fully manned surface vessel, reducing your carbon footprint and ensuring your operations are environmentally sustainable.

IHO compliant

Solus-LR is compliant with IHO standards for hydrographic surveys.
