Overview

The Underwater "Beidou" Positioning System developed by Wisdom Ocean adopts the LBL-like positioning principle to track and position the underwater UAV in real time and accurately through advanced hydro-acoustic communication technology.
Through advanced hydro-acoustic communication technology, it can track and position the underwater unmanned aerial vehicle accurately in real time and display the running information and trajectory of the unmanned aerial vehicle on the screen of the ground demonstration center.

System Features
◉ Support long-term deployment and long-term work;
◉ Large coverage area, high positioning accuracy and multi-target tracking;
◉ Convenient system expansion and support for customization.
