In a marine area near Luhuitou, Sanya, Ocean Plan collaborated with multiple research institutions to carry out an underwater ecological monitoring mission. Leveraging core functions such as underwater positioning, underwater communication, underwater data collection, and task coordination, the system played a vital role in target localization, mission interaction, and path planning. It enabled researchers to obtain real-time environmental data and collaboratively conduct coral health assessments and ecological monitoring, significantly enhancing the efficiency and safety of scientific diving operations.
