Radio navigation or radionavigation is the application of radio frequencies to determine a position on the Earth. Like radiolocation, it is a type of radiodetermination.
The basic principles are measurements from/to electric beacons, especially
- directions, e.g. by bearing, radio phases or interferometry,
- distances, e.g. ranging by measurement of travel times,
- partly also velocity, e.g. by means of radio Doppler shift.

Famous quotes containing the word radio:
“Now they can do the radio in so many languages that nobody any longer dreams of a single language, and there should not any longer be dreams of conquest because the globe is all one, anybody can hear everything and everybody can hear the same thing, so what is the use of conquering.”
—Gertrude Stein (1874–1946)
