radio navigation
Broadcast-based course plotting
Radio navigation is the use of radio signals to determine a vessel's or aircraft's position and guide its course.
Systems like GPS, VOR, and LORAN transmit signals that receivers interpret to calculate location: The pilot relied on radio navigation when visibility dropped.
The technology revolutionized travel by enabling precise positioning without visual landmarks.
