The Maritime Safety Committee

 RECALLING Article 28(b) of the Convention on the International Maritime Organization concerning the functions of the Committee,

 RECALLING ALSO resolution A.886(21), by which the Assembly resolved that the function of adopting performance standards and technical specifications, as well as amendments thereto, shall be performed by the Maritime Safety Committee on behalf of the Organization,

 RECALLING FURTHER regulations IV/10.1 and 14.1 of the International Convention for the Safety of Life at Sea (SOLAS), 1974, as amended, concerning radiocommunications for the Global Maritime Distress and Safety System (GMDSS), which require, respectively, that ships remaining in sea area A3 be provided with an Inmarsat ship earth station and that such ship earth stations shall conform to appropriate performance standards not inferior to those adopted by the Organization,

 FURTHER RECALLING resolution A.888(21) by which the Assembly adopted the criteria and requirements for mobile-satellite communication systems being designed for use in the GMDSS after 1 February 1999 and, in particular, the requirements for new systems to provide prioritised pre-emption,

 NOTING the transition of Inmarsat to a national law company and the consequential re-structuring of the International Mobile Satellite Organization (IMSO) to oversee certain public interests in the company's operations, including the continued provision of satellite services for the GMDSS,

 RECOGNIZING the need to prepare performance standards for Inmarsat satellite communication equipment designed in accordance with resolution A.888(21) in order to ensure the operational reliability of such equipment and to avoid, as far as practicable, adverse interaction between satellite communication equipment and other communication and navigation equipment aboard the ship,

 RECOGNIZING ALSO that Inmarsat discontinued type approval of Inmarsat-A ship earth stations in 1991,

 RECOGNIZING FURTHER that the international telex service is being discontinued in an increasing number of countries,

 HAVING CONSIDERED the recommendation made by the Sub-Committee on Radiocommunications and Search and Rescue at its sixth session,

  1. ADOPTS the Recommendation on performance standards for Inmarsat ship earth stations capable of two-way communications, set out in the Annex to the present resolution;

  2. NOTES that part A of the Inmarsat design and installation guidelines is similar to the performance standards for ship earth stations capable of two-way communications and to the general requirements for shipborne radio equipment set out in resolution A.694(17);

  3. RECOMMENDS Governments to ensure that every Inmarsat ship earth station which forms part of the GMDSS:

  • .1 if designed to operate in a system introduced after 1 February 1999, complies with the relevant requirements of resolution A.888(21) and conforms to performance standards not inferior to those specified in the Annex to the present resolution;

  • .2 if installed on or after 23 November 1996, conforms to performance standards not inferior to those specified in the Annex to resolution A.808(19);

  • .3 if installed before 23 November 1996, conforms to performance standards not inferior to those specified in the Annex to resolution A.698(17), which are in accordance with part A of the Inmarsat ship earth station design and installation guidelines;

  4. INVITES IMSO to ensure that any amendments to part A of the ship earth station design and installation guidelines are agreed with the Organization prior to their adoption.
