Given the technological innovations of the fourth industrial revolution, cutting-edge ICT technology has been applied in research on aids to navigation, and due to the emergence of new types of equipment and technological advancements, it is necessary to apply realistic standards to the designation of service lifetimes to aids to navigation facilities' equipment and components. In addition, it is necessary to prepare a legal basis for the effective operation of aids to navigation facilities' equipment and component. Therefore, in this paper, improvements in the designation of realistic service lifetimes are suggested by investigating the service life management and operation status of domestic and foreign aids to navigation, providing on-site surveys on the management status of aids to navigation facilities in Korea, and with a questionnaire survey to gather expert opinions.
