Modern Navigation Techniques: The Digital Revolution
Te 20 th century saw nawigation transformed by elektronics, radio, and satellites. While celestial navigation restaved a fallback, new technologies offered faster, more closate positioning, even in adverse weathers. The evolution from radio beacons to GPS represents the culmination of centiies of human ingenuity.
