Intership navigation safety communications

Intership navigation safety communications are those VHF radiotelephone communications conducted between ships for the purpose of contributing to the safe

movement of ships. The frequency 156.650 MHz is used for intership navigation safety communications (see also RR appendix 15).

 Port operation and ship movement communication

Radio traffic belonging port operation and ship movement service is a radio traffic regarding the safety of navigation. Calls for this service do not contain the safety signal e.g.:

Hamburg Pilot this is

Use of other frequencies for safety

Radio communications for safety purposes concerning ship reporting communications, communications relating to the navigation, movements and needs of ships and weather observation messages may be conducted on any appropriate communications frequency, including those used for public correspondence. In terrestrial systems, the bands 415-535 kHz (see RR Article 52), 1606.5-4000 kHz (see RR Article 52), 4000-27500 kHz (see RR appendix 17), and 156-174 MHz (see RR appendix 18) are used for this function. In the maritime mobile-satellite service, frequencies in the bands 1530-1544 MHz and 1626.5-1645.5 MHz are used for this function as well as for distress alerting purposes.

 Routine communication

Routine communications are communications which do not require any priority.
