Maritime navigation and radiocommunication equipment and systems - Class B shipborne equipment of the automatic identification system (AIS) - Part 2: Self-organising time division multiple access (SOTDMA) techniques
IEC 62287-2:2013 specifies operational and performance requirements, methods of testing and required test results for Class B "SO" shipborne AIS equipment using Self-organised TDMA (SOTDMA) techniques as described in Recommendation ITU-R M.1371. This standard takes into account other associated IEC International Standards and existing national standards, as applicable. The main differences between Class B "CS" (IEC 62287-1) and Class B "SO" units are that the Class B "SO":
- covers all 25 kHz channels listed in Recommendation ITU-R M.1084-5;
- only uses the internal GNSS, no position sensor input is allowed;
- requires use of VDL Message 17 for correction of the internal GNSS;
- has a presentation interface;
- has additional reporting intervals, down to 5 s;
- has two power settings, with a high level of 5 W;
- has the capability to transmit binary messages. It is applicable for AIS equipment used on craft that are not covered by a mandatory carriage requirement of AIS under SOLAS Chapter V.
Matériels et systèmes de navigation et de radiocommunication maritimes - Transpondeur embarqué du Système d'Identification Automatique (AIS) de classe B - Partie 2: Techniques auto-organisées d'accès multiple par répartition dans le temps (SOTDMA)
L'IEC 62287-2:2013 spécifie les exigences opérationnelles et de performance, les méthodes d'essai et les résultats d'essai exigibles pour le transpondeur embarqué du système d'identification automatique (AIS) de classe B "SO" utilisant les techniques auto-organisées TDMA (SOTDMA) telles qu'elles sont décrites dans la Recommandation UIT-R M.1371. La présente Norme prend en compte d'autres normes internationales IEC associées et des normes nationales existantes, selon le cas.
Les différences principales entre les unités de la classe B "CS" (IEC 62287-1) et de la classe B "SO" sont le fait que la classe B "SO":
- couvre tous les voies de 25 kHz énumérées dans la Recommandation UIT-R M.1084-5;
- n'utilise que le système mondial de navigation par satellite (GNSS) interne, aucune entrée provenant d'un capteur de position n’est autorisée;
- nécessite l'utilisation du message 17 sur une liaison de données en ondes métriques (VDL) pour la correction du GNSS interne;
- a une interface de présentation;
- a des intervalles de rapport supplémentaires, jusqu'à 5 s;
- a deux réglages de puissance, avec un niveau supérieur de 5 W;
- a la capacité de transmettre des messages binaires.
Elle est applicable aux équipements AIS utilisés sur le navire, qui ne sont pas visés par l'exigence relative aux AIS de bord obligatoires selon le Chapitre V de la SOLAS.
