Categories
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. | 
|
| 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. | 
|
| Consol beacon | consol | A type of long range position fixing beacon. | 
|
| Radio direction-finding station | rdf | 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. | 
|
| Aeronautical radiobeacon | aeronautical | A radio beacon designed for aeronautical use. | 
|
| Decca | decca | The Decca Navigator System is a high accuracy, short to medium range radio navigational aid intended for coastal and landfall navigation. |

|
| Differential GPS | dgps | A radiobeacon transmitting DGPS correction signals. | 
|
| Toran | toran | Toran is an electronic position fixing system used mainly by aircraft. | 
|
| Omega | omega | Omega is a long-range radio navigational aid which operates within the VLF frequency band. The system comprises eight land based stations. | 
|
| Syledis | syledis | Syledis is a ranging position fixing system operating at 420-450MHz over a range of up to 400Km. | 
|
| Chiaka (Chayka) | chiaka | Chiaka is a low frequency electronic position fixing system using pulsed transmissions at 100 Khz. |

|
| Physical AIS | ais | An AIS radiobeacon on a seamark that reports its own position | 
|
| Synthetic AIS | s-ais | An AIS radiobeacon that transmits the position of a seamark, but where the transmitter is elsewhere. |
|
| Virtual AIS (IALA function unknown) | v-ais | An AIS radiobeacon that transmits the position of a virtual aid to navigation. No physical seamark is present at the this location. | 
|
| Virtual AIS (North Cardinal Mark) | v-ais_north_cardinal | An AIS radiobeacon that transmits the position of a virtual north cardinal mark. | 
|
| Virtual AIS (South Cardinal Mark) | v-ais_south_cardinal | An AIS radiobeacon that transmits the position of a virtual south cardinal mark. | 
|
| Virtual AIS (East Cardinal Mark) | v-ais_east_cardinal | An AIS radiobeacon that transmits the position of a virtual east cardinal mark. | 
|
| Virtual AIS (West Cardinal Mark) | v-ais_west_cardinal | An AIS radiobeacon that transmits the position of a virtual west cardinal mark. | 
|
| Virtual AIS (Port Lateral Mark) | v-ais_port_lateral | An AIS radiobeacon that transmits the position of a virtual part lateral mark. | 
|
| Virtual AIS (Starboard Lateral Mark) | v-ais_starboard_lateral | An AIS radiobeacon that transmits the position of a virtual starboard lateral mark. | 
|
| Virtual AIS (Isolated Danger Mark) | v-ais_isolated_danger | An AIS radiobeacon that transmits the position of a virtual isolated danger mark. | 
|
| Virtual AIS (Safe Water Mark) | v-ais_safe_water | An AIS radiobeacon that transmits the position of a virtual safe water mark. | 
|
| Virtual AIS (Special Purpose Mark) | v-ais_special_purpose | An AIS radiobeacon that transmits the position of a virtual special purpose mark. |
