scope:

This part of IEC 61097 specifies the minimum operational and performance requirements, methods of testing and required test results for ship earth stations intended for operation in mobile-satellite systems and services which are recognized by the International Maritime Organization as meeting the criteria required by the IMO under regulation IV/4-1 of the International Convention for the Safety of Life at Sea, 1974, as amended, for the provision of mobile-satellite systems and services in the GMDSS. This standard incorporates the minimum criteria and performance standards of the IMO, currently prescribed in IMO resolution A.1001(25) in IMO resolution MSC.434(98) and is also associated with IMO resolution A.694(17) and IEC 60945. All text of this standard whose wording is identical to that of resolution MSC.434(98) is printed in italics and reference is made to that resolution and the sub-clause number. Matters relating to the installation of the ship earth station are given in Annex A.
