Maritime navigation and radiocommunication equipment and systems - Automatic identification system (AIS) - Part 1: AIS Base Stations - Minimum operational and performance requirements, methods of testing and required test results
IEC 62320-1:2015 specifies the minimum operational and performance requirements, methods of testing and required test results for AIS Base Stations, compatible with the performance standards adopted by IMO Resolution 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 Base Stations. It does not include specifications for the display of AIS data on shore. This second edition cancels and replaces the first edition published in 2007 and its Amendment 1:2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- incorporation of the technical characteristics included in Recommendation ITU R M.1371 5;
- the BCE, BCF and CAB sentences replaced with BCG, BCL and RST;
- comment blocks replaced with TAG blocks;
- scheduled broadcast of Message 26 added;
- Message 27 control added;
- transmitter intermodulation attenuation harmonised with ITU;
- 12,5 kHz channel operation removed;
- transmission of Message 24A, Message 25 and Message 26 added;
- 90 % channel load test with VSI and TAG blocks enabled added.
Matériels et systèmes de navigation et de radiocommunication maritimes - Systèmes d'identification automatique (AIS) - Partie 1: Stations de base AIS - Exigences opérationnelles et de fonctionnement minimales, méthodes d'essai et résultats d'essai exigés
L'IEC 62320-1:2015 spécifie les exigences opérationnelles et de fonctionnement minimales, les méthodes d'essai et les résultats d'essai exigés applicables aux stations de base AIS compatibles avec les normes de fonctionnement adoptées par la Résolution MSC.74(69) de l'OMI (Annexe 3, AIS universel). Elle intègre les caractéristiques techniques des systèmes AIS 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 base AIS. Elle n'inclut pas les spécifications pour l'affichage des données AIS à terre.
