Radio Navigation is the process of determining a position on the surface of the Earth by means of radio signals send from land-based transmitters. Position information is obtained typically by measurements performed on the locally received radio signal. Similar to optical observations, this includes determining the angular direction (bearing) of the transmitter station as well as estimating the distance (ranging) to the transmitter station.

Bearing-measurement systems

These systems used some form of directional radio antenna to determine the location of a broadcast station on the ground. Conventional navigation techniques are then used to take a radio fix. These were introduced prior to World War I, and remain in use today.
