AIS Aids to Navigation represent a critical component of modern maritime systems aimed at enhancing navigation safety and efficiency. AIS technology enables automatic vessel identification, precise tracking of their positions, and provision of important information about sea lanes and maritime hazards. AIS AtoNs srerve as autonomous navigation aids by providing vital signals about the geographical positions and operational status of physical and virtual navigation markers. Their integration into global maritime information systems improves coordination and navigational safety, making them pivotal in the modernization of maritime navigation. The aim of this study is to explore the importance and role of AIS navigation aids, with a specific focus on AIS AtoN devices, in enhancing maritime navigation safety and efficiency. The paper will analyze the architecture, operations, and application of AIS systems in marking sea lanes, as well as investigate their role in coordinating and securing maritime traffic. The introduction of AIS navigation aids significantly enhances maritime navigation safety and efficiency through precise vessel tracking and timely warning of maritime hazards.
