Circular (non-directional) marine or aero-marine radiobeacon
|
omnidirectional
|
A radio station which need not necessarily be manned, the emissions of which, radiated around the horizon, enable its bearing to be determined by means of the radio direction finder of a ship.
|
|
Directional radiobeacon
|
directional
|
A special type of radiobeacon station, the emissions of which are intended to provide a definite track for guidance.
|
|
Rotating pattern radiobeacon
|
rotating_pattern
|
A special type of radiobeacon station emitting a beam of waves to which a uniform turning movement is given, the bearing of the station being determined by means of an ordinary listening receiver and a stop watch. Also referred to as a rotating loop radiobeacon.

A radio station intended to determine only the direction of other stations by means of transmission from the latter.
|
|
Coast radio station providing QTG service
|
qtg
|
A radio station which is prepared to provide QTG service, that is to say, to transmit upon request from a ship, a radio signal, the bearing of which can be taken by that ship.
