Diver Navigation System

EvoLogics is proud to launch our innovative   communication and tracking system for divers:

the system offers map-based navigation, allows to set map waypoints both before and during the mission, and enables two-way text communication for divers and the dive supervision team

Diver consoles enable diver-to-diver communication with position tracking and short messages exchange.

This efficient communication and tracking system builds on an EvoLogics S2C underwater data network and integrates USBL (ultra-short baseline) positioning with simultaneous data transfers.

A diver tracking buoy with built-in GNSS and WiFi provides a bidirectional link from land or a support vessel to divers equipped with lightweight trackers based on compact EvoLogics 18/34 modems.


  • encrypted acoustic communication, range up to 1.5 km, acoustic frequency18-34 kHz

  • positioning in absolute geocoordinates, slant range accuracy +/- 10 cm

  • battery duration up to 8 hours

  • max. depth rating 50 m

  • simultaneous tracking of up to 5 divers

  • messaging to/from up to 100 divers


  • Surface team can track divers, monitor their positions, send messages, and define/change waypoints
    Divers can see their own positions and the position of the team members on a visual map

  • Divers can set and receive waypoints and points of interest and share with all team members

  • Locations can be marked in absolute geo-coordinates for later use and/or vehicle deployment

  • Divers can communicate with each  other and with the surface team

EvoLogics aimed to streamline complex underwater tasks such as search and rescue, salvage operations, recovery efforts, and cleanup operations. The Diver Navigation system enhances coordination, improves task management, and fosters efficient information sharing, ultimately increasing the effectiveness of diver operations.

The battery-powered diver unit is compatible with all EvoLogics 18/34 modems and USBL-Systems. It comes with mounts to attach it either on the diver’s scuba tank or to most of the common underwater scooters. The molded unibody design of the tracker ensures broad compatibility with various diving equipment and facilitates straightforward installation.

The diver console is a compact wrist tablet that connects to the modem tracker by cable. It provides the diver access to the SiNAPS user interface, visualizing the map of the current operations area, the positions of all divers and the support vessel, and running the text chat tool.

At the surface, the USBL buoy acts as the acoustic node for operations: the device is a mono-unit with a USBL antenna, an integrated PC running SiNAPS positioning software, a dual-antenna GNSS receiver, and a WiFi access point. Designed for mobile scenarios, the buoy ensures rapid setup and fully supports bidirectional diver tracking and message exchange.
