Subsea Modem (SuM) – The World’s First Low-Cost, Software-Defined Underwater Acoustic Modem is Made in Italy

We at SubSeaPulse SRL have recently developed SuM, the world’s first low-cost, software-defined underwater acoustic modem tailored for research and industrial applications. This innovative modem can function either as a low-power acoustic modem, employing our robust modulation and coding scheme, or as an analog front-end for testing your acoustic signals in accordance with the JANUS NATO standard.

SuM-HAT

The first Raspberry PI HAT that transforms your Raspberry non only in an analog front-end to pilot your underwater acoustic transducers, but in a complete software-defined underwater acoustic modem for all your subsea applications!

Advanced Customization

We craft bespoke solutions for marine monitoring to enhance research and promote sustainability.

Easy to Use

It’s plug-and-play and compatible with any Raspberry Pi model.

Exceeding Expectations

Our solutions are designed for precise underwater exploration and comprehensive environmental analysis.

Operational Efficiency at Sea

With its low power consumption, the SuM-HAT is the optimal choice for cost-effective, dense underwater network deployments.

Networking Abilities

The SuM-HAT can be natively integrated into complex multi-hop networks and is fully compatible with the open-source DESERT Underwater framework, developed by the University of Padova. It has been successfully tested in data-muling operations.
