Radio stations
The tags defined on this page will render in various nautical charts.
This page defines tags and values for Radio Station objects.
| Type | S100 | seamark:type | Definition | Rendering |
|---|---|---|---|---|
| Radio Station | RDOSTA | radio_station | A place equipped to transmit radio waves. |
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. | |
| Loran C | loran | Loran-C is a low frequency electronic position fixing system using pulsed transmissions at 100 Khz. | |
| 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 420-450 MHz over a range of up to 400 km. | |
| Chiaka (Chayka) | chiaka | Chiaka is a low frequency electronic position fixing system using pulsed transmissions at 100 kHz. | |
| Public communication (for conversations) | public_communication | Public communication (for conversations) | |
| Commercial broadcast | commercial_broadcast | Commercial broadcast. | |
| Facsimile transmission | facsimile | Facsimile transmission. | |
| Time signal | time_signal | Time signal. | |
| AIS base station | ais_base | An onshore AIS unit that monitors traffic in the waterways. | |
| Physical AIS | ais | An AIS radiobeacon on a seamark that reports its own position |
Other attributes
| Attribute | seamark:radio_station:<attribute> | Value type | Definition |
|---|---|---|---|
| Call sign (CALSGN) | callsign | Text | The designated call-sign of a radio station. |
| Communication channel (COMCHA) | channel | Text | A channel number assigned to a specific radio frequency, frequencies or frequency band. |
| Estimated range of transmission (ESTRNG) | range | Decimal | The estimated range of a non-optical electromagnetic transmission in nautical miles. |
| Orientation (ORIENT) | orientation | Decimal | The angular distance measured from true north to the maxima of the main lobe. |
| Signal frequency (SIGFRQ) | frequency | Integer | The frequency of the sound signal, in Hertz. |
| MMSI number (-) | mmsi | Integer | The MMSI digits |
