Recently, Ocean Plan 'Underwater Communication and Navigation System' has been applied in the Underwater scientific research project ' The Global Estuaries Monitoring Programme' in Port Shelter, Hong Kong. Marine scientists from City University of Hongkong have recognized the system and said that the system will be put into use in underwater scientific research to promote the improvement of the scientific diving system.
The Global Estuaries Monitoring (GEM) Programme belongs to The United Nations Decade of Ocean Science for Sustainable Development (2021-2030) program, with a view to developing a global network to monitor environmental contaminants (e.g. pharmaceutical residues, emerging pollutants of concern, micro-plastics, pathogens etc.) in major urbanized estuaries worldwide.
The Underwater Communication and Navigation System effectively guarantees the safety of divers in underwater scientific research, marine research and other activities, and satisfies divers' underwater real-time positioning, underwater 3D navigation, wireless messages sending and receiving, one-key SOS alarm, abnormal status warning, flexible networking form and other functional requirements. By using professional underwater acoustic communication, the system effectively solve the problems of divers being easily lost, limited communication methods, difficulties in calling for help, which improves the efficiency of underwater scientific research activities.

During this underwater scientific research, marine scientists used the Underwater Communication and Navigation System 400D series, which is composed of dive navigation computer, underwater locator beacon, control center and other products. The positioning and communication range is 400 meters, supports 2 -6 devices to be grouped and interconnected.
The interconnection networking ways include independent networking between underwater divers, and underwater divers and the surface networking, which is to build a 3D underwater positioning communication network. System's advantages like easy to operate, fast to deploy, and excellent performance like stability, flexibility and portability also received unanimous praise from experts in this activity.
