Radio navigation or radionavigation is the application of radio frequencies to determine a position of an object 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.
Usage examples of "radio navigation".
Not because you couldn't fly, but because we have no radio navigation aids to guide us to landing and because they aren't really equipped for instrument flying.
They even alter their radio navigation beacons to transmit false navigational information to aircraft near their shores, hoping to get a reconnaissance plane to fly into a restricted area.
Without TACAN, the radio navigation aid, finding the carrier would be possible only with the bomber's radar.
But he was prouder of the listening devices in his helmet, and his skill with radio navigation, and his reckonings by the stars.
The instrument panel was overloaded with switches, dials and radio navigation aids, plus a video screen which showed the aircraft's position as a dot on a moving map which had to be programmed before take-off.
The regular time variation of the radio emission from quasars and, especially, pulsars had at first been thought, tentatively, tremulously, to be a kind of announcement signal from someone else, or perhaps a radio navigation beacon for exotic ship that plied the spaces between the stars.
If aircraft had unlimited fuel supplies they could rely on radio navigation and spend as much time as they wanted cruising from destination to destination at whatever altitudes they wanted.
Surface Survival Shelters, containing food, life-support gear, medical kits, and other essentials, usually located at radio navigation beacons, were dotted all over Mars for use in emergencies.
It was nearing lunchtime when a voice came crackling over the plane's radio navigation frequency.
Luftnachrichten Battalion 350, with 800 men, served as the Luftwaffe center for basic cryptanalysis and traffic analysis, as well as for the study of new enemy radars and radio navigation systems to find the best means of jamming or deceiving them.
The thumping Stalinist scale of it made me wonder whether the sign had been built before radio navigation, so that pilots could read it while still only half-way across the Atlantic.
