Where more than one value applies, the tag value should be a semi-colon separated list.

Category (CATROS) seamark:radio_station:category Definition Rendering
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. RadioRC.png
Directional radiobeacon directional A special type of radiobeacon station, the emissions of which are intended to provide a definite track for guidance. RadioRD.png
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. RadioRW.png
Consol beacon consol A type of long range position fixing beacon. RadioConsol.png
Radio direction-finding station rdf A radio station intended to determine only the direction of other stations by means of transmission from the latter. RadioRG.png
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. RadioR.png
Aeronautical radiobeacon aeronautical A radio beacon designed for aeronautical use. RadioAero.png
Decca decca The Decca Navigator System is a high accuracy, short to medium range radio navigational aid intended for coastal and landfall navigation. RadioDecca.png
Loran C loran Loran-C is a low frequency electronic position fixing system using pulsed transmissions at 100 Khz. RadioLoran.png
Differential GPS dgps A radiobeacon transmitting DGPS correction signals. RadioDGPS.png
Toran toran Toran is an electronic position fixing system used mainly by aircraft. RadioToran.png
Omega omega Omega is a long-range radio navigational aid which operates within the VLF frequency band. The system comprises eight land based stations. RadioOmega.png
Syledis syledis Syledis is a ranging position fixing system operating at 420-450 MHz over a range of up to 400 km. RadioSyledis.png
Chiaka (Chayka) chiaka Chiaka is a low frequency electronic position fixing system using pulsed transmissions at 100 kHz. RadioChiaka.png

Time signal time_signal Time signal. RadarStation.png
AIS base station ais_base An onshore AIS unit that monitors traffic in the waterways. RS-AIS.png
Physical AIS ais An AIS radiobeacon on a seamark that reports its own position RS-AIS.png
