Maritime navigation and radio communication equipment and systems - Automatic identification systems (AIS) - SAR airborne equipment - Operational and performance requirements, methods of test and required test results

IEC 63135:2018 specifies the minimum operational and performance requirements, methods of testing and required test results as applicable for automatic identification systems (AIS) VHF data link (VDL) related parts of an AIS SAR airborne station. This document incorporates the applicable technical characteristics of AIS SAR airborne equipment included in Recommendation ITU-R M.1371 and takes into account the ITU Radio Regulations, where applicable.
This document also specifies the minimum requirements for the interfaces to other equipment suitable to be used as means of input and display data.
Attention is drawn on that other requirements specific for airborne equipment can exist and are beyond the scope of this document.

Matériels et systèmes de navigation et de radiocommunication maritimes - Systèmes d'identification automatique (AIS) - Equipement aéroporté SAR - Exigences d'exploitation et de fonctionnement, méthodes d'essai et résultats d'essai exigés

L'IEC 63135:2018 spécifie les exigences minimales d'exploitation et de fonctionnement, les méthodes d'essai et les résultats d'essai exigés applicables aux parties de la station aérienne AIS SAR en lien avec la liaison de données VHF (VDL) des systèmes d'identification automatique (AIS). Le présent document comporte les caractéristiques techniques applicables des équipements AIS SAR aéroportés incluses dans la Recommandation UIT-R M.1371 et tient compte, le cas échéant, du Règlement des radiocommunications de l'UIT.
Le présent document spécifie également les exigences minimales applicables aux interfaces des autres équipements appropriés pour entrer et afficher des données.
L'attention est attirée sur le fait que d'autres exigences spécifiques aux équipements aéroportés peuvent exister et ne relèvent pas du domaine d'application du présent document.
