GMDSS operating position at the Brisbane communications centre
The GMDSS is a system put in place internationally to enable rapid alerting of a marine distress situation to take place. This in turn enables search and rescue proceedings to be implemented with the minimum of time lost.
system involves the use of one or more methods of communication including
Digital Selective Calling (DSC),
Emergency Position Indicating Radio Beacons (EPIRBS),
Search and Rescue Transponders (SARTS) as well as voice radiotelephone
and Inmarsat communications.
July 2002, DSC functions will be provided by two new stations at Charleville,
Queensland and Wiluna, Western Australia and remotely controlled from
an operations centre in Canberra. This service
will be operated by TVNZ.
Maritime Communications Stations monitor the HF GMDSS frequencies and broadcast weather reports and navigational warnings at scheduled times. From 1st July 2002, this role will be taken over by State Government Authorities.
The basic concept of the GMDSS is that search and rescue authorities ashore, as well as shipping in the immediate vicinity of the ship, or persons, in distress, will be rapidly alerted to a distress incident so they can assist in a co-ordinated search and rescue operation with the minimum delay.
The system also provides for urgency and safety communications and the promulgation of maritime safety information (navigational and meteorological warnings and forecasts and other urgent safety information).
In other words, every ship is able, irrespective of the area in which it operates, to perform those communication functions which are essential for the safety of the ship itself and of other ships operating in the same area.
