BS EN 61108 discusses marine navigation and radiocommunication equipment, systems and global navigation satellite systems (GNSS).
BS EN 61108-4 is the fourth part of BS EN 61108 multi-series and discusses performance requirements, methods of testing and required test results of shipborne DGPS and DGLONASS maritime radio beacon receiver equipment.
BS EN 61108-4 may be satisfied by equipment integral with GNSS equipment. BS EN 61108-4 is applicable to HSC. BS EN 61108-4 covers the basic requirements of maritime radio beacon receiver equipment providing augmentation information to Position-fixing equipment, including health messages.
BS EN 61108-4 on shipborne DGPS and DGLONASS maritime radio beacon receiver equipment is useful for:
Differential services broadcast information for augmenting Global Positioning System (GPS) and the Global Navigation Satellite System (GLONASS) to provide the accuracy and integrity required for entrances and harbour approaches and other waters in which the freedom to manoeuvre is limited. Various service providers are broadcasting differential information applicable to localised areas.
BS EN 61108-4 provides you with the minimum operational and performance requirements, methods of testing and required test results conforming to performance standards not inferior to those adopted by the IMO in resolution MSC.114(73). In addition, it takes account of IMO resolution A.694(17) and is associated with IEC 60945. BS EN 61108-4 helps you to provide high-quality shipborne DGPS and DGLONASS maritime radio beacon receiver equipment.
