Maritime navigation and radiocommunication equipment and systems - Automatic identification systems (AIS) - Part 3: Repeater stations - Minimum operational and performance requirements - Methods of test and required test results

IEC 62320-3:2015 specifies the minimum operational and performance requirements, methods of testing and required test results for AIS repeater stations, compatible with the performance standards adopted by IMO Res. MSC.74 (69), annex 3, Universal AIS. It incorporates the technical characteristics of non-shipborne, fixed station AIS equipment, included in Recommendation ITU-R M.1371 and IALA Recommendation A-124. Where applicable, it also takes into account the ITU Radio Regulations. This standard takes into account other associated IEC International Standards and existing national standards, as applicable. This standard is applicable for AIS repeater stations. It does not include specifications for the display of AIS data on shore.

Matériels et systèmes de navigation et de radiocommunication maritimes - Systèmes d'identification automatique (SIA) - Partie 3: Station de répéteurs - Exigences minimales d'exploitation et de performances - Méthodes d’essai et résultats d’essai exigibles

L'IEC 62320-3:2015 spécifie les exigences minimales d'exploitation et de performances, les méthodes d'essai et les résultats exigibles pour les stations de répéteurs SIA conformes aux normes de performances adoptées par l'Annexe 3 de la Résolution MSC.74 (69) de l'OMI, SIA universel. Elle intègre les caractéristiques techniques des systèmes SIA de station fixe non embarquée, incluses dans la Recommandation UIT-R M.1371 et la Recommandation IALA A-124. Le cas échéant, elle tient compte également des réglementations de radiodiffusion de l'UIT. La présente norme s'appuie sur d'autres Normes internationales de l'IEC associées et sur des normes nationales existantes, selon le cas.
La présente norme s'applique aux stations de répéteurs SIA. Elle n'inclut pas les spécifications pour l'affichage des données SIA à terre.
