对全球导航卫星的信号体制进行了专利检索分析,综合考虑信号调制、多路复用等技术,分别以导航卫星的信号调制方式、信号生成方式、信号编码方式为检索领域,对全球导航卫星系统申请专利进行全面而系统的检索。在初检基础上,以空间段、星上技术为依据进行复检并深入分析,指出该领域未来发展方向。为我国未来全球导航卫星系统信号体制的设计提出知识产权规避措施和发展建议。
The global navigation satellite system has been patented to search and analyze the signal. Synthetically considering signal modulation and multiplexing technology, the navigation satellite signal modulation method, signal generation method and signal coding method are respectively used as the search fields. The global navigation satellite system Apply for a patent for a comprehensive and systematic search. On the basis of preliminary examination, re-examination and in-depth analysis are conducted on the basis of space segment and satellite technology, indicating the future development direction in this field. Proposed Intellectual Property Avoidance Measures and Suggestions for the Design of China’s Future GNSS Signal System.
