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:
“England has the most sordid literary scene I’ve ever seen. They all meet in the same pub. This guy’s writing a foreword for this person. They all have to give radio programs, they have to do all this just in order to scrape by. They’re all scratching each other’s backs.”
—William Burroughs (b. 1914)
