IEC released the first international standard for testing ship-borne receiver equipment of the Chinese BeiDou Navigation Satellite System (BDS). According to Wikipedia, BeiDou-3, the third generation of the Chinese satnav system, is expected to consist of 35 satellites and completion is planned for the first half of 2020. It will provide an alternative to the US-owned Global Positioning System (GPS), the Russian GLONASS or European Galileo systems. BDS is also known as the Compass Navigation Satellite System.
According to specialized press reports, BeiDou will deliver two types of services: a free service that is open for everyone with a compatible terminal and a licensed service for the Chinese government to use in military and other areas.
The IEC Standard, IEC 61108-5, was published on March 11, 2020. This receiver standard applies to navigation in the ocean, coastal, harbour entrances, harbour approaches and restricted waters, as defined in International Maritime Organization (IMO) resolution 22 and 27. IEC 61108-5 specifies the minimum performance requirements, methods of testing and required test results for BDS ship-borne receiver equipment. The document is associated with several other standards issued by IEC Technical Committee 80: Maritime navigation and radiocommunications equipment and systems, notably for Galileo GLONASS and GPS receiver systems.
IEC 61108-5 will notably help manufacturers of BDS-related maritime devices to design, produce, and test their products. “I would like to thank the project leader for this standard, Mrs Yang Wenhui of the Xi’an Research Institute of Navigation Technology, who put considerable effort into the project,” says Kim Fisher, IEC TC 80 Secretary.
Two new categories of requirements have been added, which are not included, notably in the previous IEC Standards for Galileo and GPS receiver systems. The first set of requirements concerns the presentation of navigation-related information, including positioning accuracy, capture time and sensitivity, in order to reflect the performance of the BDS; Other specifications have to do with new contents such as ship bridge alarm management, in compliance with new IMO guidelines.
