Transatlantic radio navigation

Transatlantic radio navigation is a method used by ships and aircraft to determine their position across the Atlantic Ocean using radio signals. It relies on powerful radio beacons or navigation stations positioned along the coastlines and across the ocean, which emit precise signals. Receivers aboard vessels or aircraft pick up these signals and measure the time and direction they arrive, allowing navigators to calculate their location by triangulating multiple signals. This technique was especially vital before GPS, providing a reliable way to navigate vast ocean distances safely and accurately.
