WG 8 - TC 80/WG 8

IEC 61097-4:2012(E) specifies the performance requirements and methods of testing for Inmarsat-C ship earth stations (SES) capable of transmitting and receiving direct-printing communications, and for enhanced group call (EGC) receivers, for use in the GMDSS and for use for long-range identification and tracking (LRIT).

Specifies the minimum performance requirements, technical characteristics and type-testing requirements for narrowband telegraph equipment for the reception of navigational and meteorological information as required by the International Convention for Safety of Life at Sea (SOLAS), and which is associated with IEC 60945. Also incorporates the performance standards of the relevant IMO resolutions and conforms with the ITU-R regulations where applicable.

Specifies the minimum requirements for shipborne receivers intended to be connected to an external installation, including a decoder for digital selective calling (DSC), and used as receivers for watchkeeping on DSC channels on board ships operating in the maritime mobile MF, MF/HF and VHF bands.

Specifies the minimum operational and performance requirements and methods of testing for transmitters and receivers capable of voice communication, digital selective calling and narrow band direct printing telegraphy for the GMDSS operating in either the medium frequency band only or in medium and high frequency bands.

Specifies the minimum performance requirements, technical characteri stics and methods of testing of survival craft portable two-way radiotelephone apparatus as required by the 1988 amendments to the 1974 International Convention for the Safety of Life at Sea (SOLAS).

Specifies the minimum performance requirements, technical characteristics and methods of testing with required test results for VHF radio installations capable of voice communication and digital selective calling as required by the 1988 amendments to the 1974 International Convention for Safety of Life at Sea (SOLAS). Is associated with IEC 60945.

Specifies the minimum operational and performance requirements, technical characteristics, methods of testing and required test results for INMARSAT F77 ship earth stations (SES), capable of transmitting and receiving distress and safety communications, initiating and receiving distress priority calls and transmitting and receiving general radiocommunications, using radiotelephony (voice), as required within the relevant IMO Regulations.
