Navigational aids are tools and devices that help people find their way while traveling, whether on land, at sea, or in the air. Common examples include lighthouses, buoys, and road signs. These aids provide important information about directions, distances, and hazards, making navigation safer and more efficient. In addition to physical markers, navigational aids also include technology like GPS (Global Positioning System) and compasses. These tools use signals and magnetic fields to help users determine their location and orientation. Together, these aids play a crucial role in guiding travelers and ensuring they reach their destinations accurately.
