LORAN S, or Long Range Navigation System, is a navigational aid used for maritime and aviation purposes. It relies on radio signals for determining position and providing guidance. While LORAN S is the commonly recognized term for this system, there are synonyms and related terms worth noting. One such synonym is LORAN C, a previous version of the system used until the early 2000s. Additionally, terms like hyperbolic radio navigation, Hiperbólica, and Decca Navigator System are variations used in different parts of the world. Though these terms may differ, their purpose remains the same: assisting navigators in accurately determining their location and reaching their destinations safely.
