Low cost CTD

The low coast CTD unit is available either as an OEM module or enclosed in a underwater casing. Once wired to a host, it streams temperature and depth readings over a simple UART interface. The optional casing houses a rechargeable battery, a microSD storage and a management software, allowing fully autonomous operation and on‑board data logging.

Ethernet Digitizer

The Ethernet Digitizer captures analog signals from up to four acoustic sensors and streams the digitized data in real time over a standard 100 Mbps Ethernet link. Designed for modularity, the unit can be used bare or fitted in an underwater casing.

Long Range Modem

An eDPC‑enabled embedded solution integrates with LORAAL’s firmware, delivering low‑power, real‑time communication scheduling, adaptive modulation, and fault‑tolerant operation.

This compact solution guarantees reliable acoustic links on embedded devices.

Smart-Recorder

Introducing the Seagnal Smart Recorder, a compact, underwater audio logger designed for marine application. With a user‑mounted hydrophone, the system delivers high‑bandwidth acoustic recordings from deep‑sea to shore. Its rugged enclosure and built‑in motion sensors continuously track position and depth.

Smart-Pinger

A configurable acoustic beacon that produces any user‑defined waveform with precise timing. Leveraging surface‑GPS synchronization, it delivers sub‑millisecond accuracy during 8h, enabling reliable triangulation and time‑of‑flight measurements for underwater navigation and monitoring systems.
