Abstract: Currently, the worldwide shipborne satellite navigation receiving equipment generally applies the IEC 61108 series standards issued by TC 80 of International Electrotechnical Commission (IEC). The issued IEC 61108 series standards include standards for performance requirements and test methods of receiving equipment of GPS, GLONASS, GALILEO, DGPS and DGLONASS. Considering the independence of receiving equipment of DGPS and DGLONASS and its less correlation with other standards, the article does not make any comparison among them. The article mainly analyzes the prevailing series standards of IEC 61108-1～3 by introducing the differences and existing problems, including inaccurate description and not applicable to current technology development. and puts forward the proposals.
