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:
“from above, thin squeaks of radio static,
The captured fume of space foams in our ears—”
