Description

DiveNET: Commander is a compact, multi-function and multi-target Ultra-Short Base Line (USBL) underwater navigation solution designed for diver and unmanned applications.

Commander provides multi-function service:

  • Relative Bearing tracking
  • Absolute coordinate tracking with track recording
  • Underwater navigation support (distance and direction to base station)
  • Autonomous or carrier-integrated operation
  • Transmission of remote code commands and telemetry

The Commander Transponder (COMT) subsea unit is available with a battery pack for autonomous operation or in standalone configuration for integration with carrier systems. Transponders are available for 300 m and 1,000 m (OEM) maximum depths.

Each COMT beacon supports 16 system commands, 16 user commands and provides own telemetry to the base station.

Each COMT beacon receives the base station azimuth from the MAST topside antenna while independently measuring range, water depth and temperature. 

The Master Transceiver (MAST) topside base station antenna supports interfacing with surface GNSS to enable absolute coordinate operation and track recording.

DiveNET: Commander is designed for effective, robust operation in real-world conditions, requiring minimal configuration and maintenance. The system is supplied with dedicated, open-source code operating software.
