Constellations can be used as a rough guide for navigation by using them to determine direction based on their position in the sky. By recognizing specific constellations and their orientation, such as the North Star in the Northern Hemisphere, navigators can orient themselves and find cardinal directions to help guide their way. However, relying solely on constellations for navigation may not be as precise as using modern tools like GPS.
