Last updated Ship station dedicated to port operation service.
Port operations service (short: POS; | also: port operations radiocommunication service') is – according to Article 1.30 of the International Telecommunication Union´s (ITU) Radio Regulations (RR)[1] – defined as «A maritime mobile service in or near a port, between coast stations and ship stations, or between ship stations, in which messages are restricted to those relating to the operational handling, the movement and the safety of ships and, in emergency, to the safety of persons. Messages which are of a public correspondence nature shall be excluded from this service.»
The International Telecommunication Union, originally the International Telegraph Union, is a specialized agency of the United Nations (UN) that is responsible for issues that concern information and communication technologies. It is the oldest among all the 15 specialised agencies of UN.
The ITU Radio Regulations regulates on law of nations scale radiocommunication services and the utilisation of radio frequencies. It is the supplementation to the Constitution and Convention of the International Telecommunication Union. In line to the ITU Constitution and Convention and the ITU International Telecommunication Regulations (ITR), this ITU Radio Regulations belong to the basic documents of the International Telecommunication Union. The ITU Radio Regulations comprise and regulate the part of the allocated electromagnetic spectrum from 9 kHz to 275 GHz.
A maritime mobile service is a mobile service between coast stations and ship stations, or between ship stations, or between associated on-board communication stations. The service may also be used by survival craft stations and emergency position-indicating radiobeacon stations.
The ITU Radio Regulations classifies this radiocommunication service as follows: Mobile-satellite service (article 1.25)
Mobile-satellite service is – according to Article 1.25 of the International Telecommunication Union's Radio Regulations – "A radiocommunication service
Maritime mobile-satellite service is – according to Article 1.29 of the International Telecommunication Union's Radio Regulations (RR) – "A mobile-satellite service in which mobile earth stations are located on board ships; survival craft stations and emergency position-indicating radiobeacon stations may also participate in this service".
Ship movement service is – according to Article 1.31 of the International Telecommunication Union´s (ITU) Radio Regulations (RR) – defined as «A safety service in the maritime mobile service other than a port operations service, between coast stations and ship stations, or between ship stations, in which messages are restricted to those relating to the movement of ships. Messages which are of a public correspondence nature shall be excluded from this service.»
