Introduction
1. Regulation 5, chapter IV of the 1988 Amendments to the 1974 SOLAS Convention to introduce the Global Maritime Distress and Safety System (GMDSS) requires each Contracting Government to make available, as it deems practical and necessary, either individually or in co-operation with other Contracting Governments, appropriate shore-based facilities for space and terrestrial radiocommunication services having due regard to the recommendations of the Organisation. These services are:
1. a radiocommunication service utilising geostationary satellites in the Maritime Mobile-Satellite Service;
2. a radiocommunication service utilizing polar orbiting satellites in the Mobile-Satellite Service;
3. the Maritime Mobile Service in the bands between 156 MHz and 174 MHz;
4. the Maritime Mobile Service in the bands between 4,000 kHz and 27 ,500 kHz; and
5. the Maritime Mobile Service in the bands between 415 kHz and 535 kHz and between 1,605 kHz, and 4,000 kHz.
Regulation 5 also provides that:
"Each Contracting Government undertakes to provide the Organisation with pertinent information concerning the shore-based facilities in the Maritime Mobile Service, Mobile-Satellite Service and Maritime Mobile-Satellite Service, established for sea areas which it has designated off its coasts."
2. The Maritime Safety Committee at its fifty-fourth session, in April-May 1987, approved for circulation to Member Governments MSC/Circ.468 -"Information on shore-based facilities in the Global Maritime Distress and Safety System (GMDSS)", requesting Member Governments to provide, as soon as possible, information in accordance with a questionnaire attached thereto to allow development of a Master Plan of shore-based facilities for the GMDSS.
3. At its fifty-fifth session, in Apri11988, the Committee authorised a meeting of an ad hoc Group to develop the GMDSS Master Plan and to prepare, mainly on the basis of information received, a report to the 1988 Maritime Safety Conference on the GMDSS containing their conclusions and recommendations. The Conference noted the Group's report and took actions as recommended therein.
4. The Sub-Committee on Radiocommunications (COM) at its thirty-seventh session, in July 1991, agreed that sufficient progress had been made in the development, of the Master Plan and that the information so far collected should be circulated as GMDSS/Circ.1 before the entry into force, on 1 February 1992, of the 1988 Amendments to the 1974 SOLAS concerning radiocommunications for the GMDSS.
5. This circular supersedes GMDSS/Circ.1 and contains the latest information on the GMDSS Master Plan based upon replies received from Member Governments in response to the questionnaire circulated by MSC/Circ.468/Rev .1 and MSC/Circ.468/Rev .2.
6. Member Governments who have responded to the questionnaire are invited to examine the details of their shore-based facilities for the GMDSS given in the attached Master Plan and to submit to the Organisation, using MSC/Circ.468 or annex 12 to GMDSS/Circ.1 , any corrections or additional information they wish to include in the Master Plan.
7. Member Governments who have not responded to the questionnaire are invited to provide the information requested in MSC/Circ.468/Rev .2 as soon as possible.
8. Additional information and corrections received from Member Governments will be circulated by the Organisation as soon as possible after receipt, as GMDSS circulars. A list thereof will be submitted periodically to the COM Sub-Committee for information and action as necessary.
9. Member Governments, ITU, ICAO, WMO, IHO, INMARSAT and the COSPAS-SARSAT Partners are requested to bring this circular, and the information annexed hereto, to the attention of maritime, aviation, telecommunication, hydrographic and meteorological authorities, SAR authorities, maritime rescue co- ordination centres (MRCCs), aeronautical rescue co-ordination centres (ARCCs), coast earth stations (CESs), coast stations (CSs), COSPAS-SARSAT mission control centres (MCCs), hydrographers, shipowners, training institutions and seafarers. |
