About

● The EvoLogics USBL Buoy is a fully integrated, plug-and-play surface gateway for real-time tracking of underwater assets: all in one single, compact system.
Simply unfold its antennas, set it into the water, and it’s ready to go - no pre-deployment calibration required.

Equipped with a USBL transceiver, AHRS, dual GNSS antennas, onboard PC, wireless access point and rechargeable battery, the buoy delivers accurate geo-referenced USBL positioning and seamless data exchange straight out of the box.

The design of its lightweight, robust carbon and glass fiber housing is inspired by fishing floats, ensuring stable operation in coastal and offshore environments. Designed for rapid deployment, it can be transported, assembled, and operated by a single person.

The buoy runs EvoLogics’ SiNAPS software onboard, and is a full-fledged EvoLogics modem inside - allowing live data exchange, custom scripting, and integration with your own software to adapt the unit to the specifics of your application.

Key Components

The EvoLogics USBL Buoy combines USBL positioning essentials:

Single-Body All-In-One Unit

A compact, floating system that contains all core components for underwater positioning and communication. Simply unfold the antennas, set the buoy into the water, power up – and it is ready. Its rugged carbon and glass fiber housing ensures stability and reliability in diverse weather conditions.

SiNAPS Positioning Software

SiNAPS is the onboard software platform for processing positioning data and mission control. It calculates and outputs locations of tracked assets, accessible via the SiNAPS GUI through wireless connection from shore. No client app is necessary - simply open the interface in a modern web browser for a map-based view and full mission control.
