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(E) 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: Stations de répéteurs – Exigences minimales d'exploitation et de performances - Méthodes d’essai et résultats d’essai exigés

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.

Pomorska navigacijska in radiokomunikacijska oprema in sistemi - Sistemi za avtomatično identifikacijo (AIS) - 3. del: Simpleksna repetitorska postaja AIS - Minimalne obratovalne in tehnične zahteve, preskusne metode in zahtevani rezultati preskušanja

Ta del standarda IEC 62320 določa minimalne obratovalne in tehnične zahteve, preskusne metode in zahtevane rezultate preskušanja repetitorskih postaj AIS, ki so v skladu z izvedbenimi standardi, ki jih je sprejela Mednarodna pomorska organizacija v dodatku 3 k resoluciji MSC.74(69), Univerzalne bazne postaje AIS. Vključuje tehnične lastnosti neladijske opreme fiksne postaje AIS, vključene v priporočilu ITU-R M.1371 in Priporočilu IALA A-124. Upošteva tudi Pravilnik o radiokomunikacijah ITU, kjer je to primerno. Ta standard upošteva druge povezane mednarodne standarde IEC in obstoječe nacionalne standarde, kakor je primerno.
Ta standard se uporablja za repetitorske postaje AIS. Ne vključuje specifikacij za prikaz podatkov AIS na kopnem.
