With the development of maritime ICT, the introduction of e-navigation and the MASS (maritime autonomous surface ship), the types and scope of maritime communication networks are expanding, and the need for digital AtoN services is increasing. However, due to problems such as the aging of fishing crews, coastal backlight, weather conditions, and inexperience with regard to the use of advanced navigation equipment on board, the visual and electronic perception of AtoN is degraded, and it is difficult to ensure safe ship navigation. In this study, in response to the introduction of the MASS, a plan for the development of an active customized virtual digital AtoN service system in consideration of ship operating conditions and geographic conditions is proposed. The proposed service system may facilitate electronic identification of AtoN and contribute to preventing marine accidents by ensuring the safe navigation of ships.
