Non-Directional Beacon
NDB
  • a low or medium radio navigation service transmitting signals whereby the pilot of a suitably equipped aircraft can determine bearings, 'home in' on, and/or track to or from the station
Good to know
  • Valdkond ICAO lisade põhjal loodud klassifikaatori järgi: Lennundusside (telekommunikatsioon)
  • HF alas töötav raadiomajakas, lähenemisalas ka LO ja LOC
Good to know
  • The radio frequencies assigned to an NDB shall be selected from those available in that portion of the spectrum between 190 and 1750 kilohertz (kHz).

NDB
  • raadiomajakas, mis ei sisalda olemuslikku suunateavet
  • radio beacon which does not include inherent directional information
suunata raadiomajakas preferred
Usage examples
  • Suunata raadiomajakas ehk ringsuunaline raadiomajakas on lühimaa raadionavigatsiooniseade, mille abil on õhusõidukil võimalik kindlaks määrata oma asukoht, kuna see raadiomajakas levitab enda ümber igas suunas kindla sagedusega raadiolaineid, mis on vahemikus 190 kHz kuni 535 kHz, ja edastab oma sagedusel morse koodis pikkade ja lühikeste helisignaalidega määratud kolmekohalist tunnuskoodi.
non-directional radio beacon preferred
Usage examples
  • A non-directional radio beacon (NDB) or omnidirectional radio beacon is a short-range radio navigation aid that allows an aircraft to determine its position; the beacon radiates radio waves in all directions at a specific frequency within the 190 kHz to 535 kHz range and transmits an assigned three-character identification code in Morse code using long and short audio signals.
