navigation aids
Tools for orientation
Navigation aids are devices, systems, or markers that help travelers determine position or course.
The term covers everything from lighthouses and buoys to radio beacons, GPS satellites, and runway lights.
Pilots and mariners rely on navigation aids to stay on track, especially in poor visibility: The fog was thick, but the navigation aids brought us safely into harbor.
