Commercialization of AIS, it make be possible to provide VTS service efficiency and to decide quickly navigational action among vessels. Communications at sea mostly doing by communicating equipments(SSB, VHF, etc.). Especially, it is impossible to provide VTS service to non-listening vessels and non-reponse vessels. These vessels are main reason that make the problems communcating among vessels at sea. Solution of these, Displaying stand by channel of each vessels in real time, it can be improve response rate(factor) to non-listening vessels and non-response vessels. It will bhe helpful to improve safety at sea.
