IEC 61097-10:1999 pdf download – Global maritime distress and safety system(GMDss)- Part 10: lnmarsat-B ship earth station equipment -perational and performance requirements,methods of testing and required test results.
This part 0f IEC 61097 specifies the minimum operational and performance requirements. technical characteristics, methods of testing and required test results for Inmarsat-B maritime class 1 ship earth stations (SES), capable of transmitting and receiving distress and salety communications usin9 telephony and direct-printing telegraphy. as required by regulation IV 10_i and 14.1 of the 1988 amendments to the 1974 International Convention for the Safety of Life at Sea (SOLAS), or use In the GMDSS.
In order to meet the carriage requirements of the GMDSS in respect of receipt of SafetyNET broadcasts, ii is necessary to install an addit,onal EGC receiver or a combined InmarsatC1EGC receiver.
This standard takes account of IMO Resolution A.694, to which IEC 60945 is associated. When a requirement in this standard is different from IEC 60945, the requirement in this standard takes precedence.
This standard incorporates the performance standards of IMO Resolution A.808. It also incorporates the relevant ITU Radio regulations.
This standard does not incorporate the Inmarsat system requirements needed for Inmarsat type approval. For these, the latest edition of the lnmarsat-B system definition manual (SOM) shall be consulted. When a requirement in this standard is different from one in the lnmarsat-B SDM. reference shall be made to the most recent MO and ITU applicable documents to resolve the difficulty.

4 General and operational requirements
4.1 General
This clause includes the requirements taken from SOLAS and IMO Resolutions A.808 and A694 for which no repeatable or verifiable test can be specified or for which the test is limited to the verification of documentation presented by the manufacturer. It contains all operational tests, particularly those involving subjective judgement and which shall be conducted by qualified personnel. The requirements listed in this clause are in addition to the relevant operahonal requirements of IEC 60945.
4.2 General requirements
4.2.1 (SOLAS lVIlO.1.1) An Immarsat ship earth station which is defined in the lnmarsat-B SDM as a maritime class I SES shall be capable of:
4.2.3 (A.8081A.1) The ship earth station installation capable 01 telephony and direct printing shall comply with the applicable general requirements set out in IMO resolution A.694 (17) as detailed in lC 60945, except as follows:
4.2.3.1 The equipment shall Indicate the Status of the distress alert transmission (4.2.9 of IEC 60945).
4.2.3.2 The equipment shall be provided with facilities which permit the testing of all operational indicators (warning, alarm and routine), displays, and audible devices required by the relevant equipment standard (4.2.9 of IEC 60945).
4.3 Operational requirements for lnmars.at.B maritime class I SES
4.3.1 (A.80aA,3,i) No control external to the equipment shall be available for alteration of the ship earth station identity.
4.3.2 (A,8081A.3.2) It shall be possible to initiate and make distress calls by telephony or direct printing from the position at which the ship is normally navigated and from any position designated for distress alerting. In addition, where a room is provided for radio communications, means to initiate distress calls shall also be filled in that room.
4.3.3 (A.808A.3.3) Where no other means of receiving distress, urgency and safety broadcasts or an additional distress alert relay are provided and existing levels of aural signals produced by the telephone or teletype are considered to be inadequate, the ship earth station equipment shall be configured to actuate an auralvisual alarm of appropriate level.
