Commercial Options

The LAUV can be configured according to the costumer needs. The system is operated with NEPTUS (Command and Control User Interface), there is no need to use third party software to review collected data. Multi-vehicle operations are also supported.

Distinguishable features

The LAUV is a Lightweight AUV targeted at innovative standalone or networked operations for cost-effective oceanographic, hydrographic and security and surveillance surveys. NEPTUS is the LAUV Command and Control User Interface. As a complete software framework was designed to support all user’s actions in all stages of the mission life cycle: plan and design, simulation, execution, monitoring and data analysis.
