EvoLogics has announced the new USBL buoy, a fully integrated solution based on the company’s S2C USBL devices.

The buoy comprises a USBL transceiver with a built-in battery, mounted to a floating unit

The buoy comprises a USBL transceiver with a built-in battery, mounted to a floating unit with an on-board PC, GNSS receiver with dual antennas, and a Wi-Fi access point.

The design concept of the system derives from fishing floats that remain highly stable even in rough seas thanks to their long stems and minimal cross-section near the surface.

This integrated system eliminates the need to use external GNSS receivers for geo-referenced positioning of underwater targets. Dual GNSS antennas provide accurate yaw measurements without being affected by magnetic interferences. The on-board PC runs the pre-installed SiNAPS, EvoLogics positioning software.

The buoyant body of the unit is made of carbon and glass fibre composites, making it lighter, more compact and robust than conventional designs with foam-based floatation collars.

Launching in December 2020, the buoy is available with all models of the EvoLogics S2C USBL range.

MJ Glossary: Ultra Short Baseline (USBL) is a widely used tracking system for ROVs (Remotely Operated Vehicles- underwater) and autonomous or remotely operated surface vessels.
