IEC 61108-3:2010

Maritime navigation and radiocommunication equipment and systems - Global navigation satellite systems (GNSS) - Part 3: Galileo receiver equipment - Performance requirements, methods of testing and required test results

IEC 61108-3:2010 specifies the minimum performance standards, methods of testing and required test results for Galileo shipborne receiver equipment, based on IMO resolution MSC.233(82), which uses the signals from the Galileo Global Navigation Satellite System in order to determine position. It takes account of the general requirements given in IMO resolution A.694(17) and is associated with IEC 60945.

Matériels et systèmes de navigation et de radiocommunication maritimes - Système mondial de navigation par satellite (GNSS) - Partie 3: Matériel de réception Galileo - Exigences d'exploitation et de fonctionnement, méthodes d'essai et résultats d'essai exigés

L'IEC 61108-3:2010 spécifie les exigences minimales en matière de normes de fonctionnement, de méthodes d'essai et de résultats d'essai exigés pour le matériel de réception de bord Galileo, conformément à la résolution MSC.233(82) de l'OMI, et qui utilise les signaux provenant du système mondial de navigation par satellite Galileo afin de déterminer une position. Elle prend en compte les exigences générales de la résolution A.694(17) de l'OMI et est associée à l'IEC 60945. Lorsqu'une exigence de cette norme diverge de l'IEC 60945, c'est l'exigence de la présente Norme qui prévaut. Elle prend également en compte, selon le cas, les exigences de présentation des informations relatives à la navigation sur les écrans de navigation de bord explicitées dans la résolution MSC.191(79) de l'OMI et est associée à l'IEC 62288.
