Marine Instruments

Marine Instruments is a Spanish technology company specialized in advanced sensing solutions and unmanned systems for maritime and underwater operations.

Building on more than two decades of experience developing autonomous ocean platforms, acoustic sensors and satellite-connected monitoring systems, the company focuses on enhancing situational awareness across the maritime domain — from seabed to airspace. Its technologies enable persistent monitoring of the ocean environment through distributed networks of sensors and autonomous platforms designed to operate in complex maritime conditions.

These capabilities support missions such as maritime ISR, protection of critical subsea infrastructure, and wide-area ocean surveillance.

The M5D-AIRFOX unmanned aerial system, deployed aboard Spanish Navy offshore patrol vessels, extends surveillance reach by providing long-endurance aerial ISR and rapid deployment of sensing payloads.

By integrating autonomous systems, underwater acoustics, and satellite communications, Marine Instruments is helping shape scalable, networked sensing architectures for the future digital maritime domain.
