摘要
通过回顾总结国内外卫星导航系统的发展过程,分析提出卫星导航系统的技术特征与指标。从技术途径、系统服务的角度聚焦于空间星座、时空基准、导航信号、导航增强、多功能融合方面,系统梳理卫星导航系统的现状和建设发展过程中的技术创新,展望其发展趋势和相关关键技术方向,以期为中国卫星导航系统建设及定位导航授时体系构建提供支持。
By reviewing the development of satellite navigation systems in China and other countries, this paper discusses the technical characteristics and indexes of the systems. It focuses on spatial constellation, space-time datum, navigation signal,navigation augmentation, and multi-function integration from the perspectives of technical approach and system service. In addition to systemically introducing the present status of satellite navigation systems and their technical innovation during development, the paper also provides an outlook on their development trend and related key technologies. This review can support the construction of satellite navigation systems and positioning, navigation and timing(PNT) systems in China.
