摘要
卫星导航发展已进入百花齐放、群星争艳的时代。主要评述我国北斗卫星导航系统的发展、应用、贡献及面临的挑战。介绍北斗卫星导航系统的建设原则和建设步骤;介绍我国北斗卫星导航系统在兼容与互操作框架下在频率、坐标系统、时间系统方面的兼容与互操作实现概况;描述北斗导航系统在冗余度概念下的主要贡献;简要说明北斗导航验证系统的重要应用和面临的主要挑战。
Satellite navigation has stepped into the era of a hundred flowers in bloom. The progress, application, contribution and challenges of Compass/Beidou satellite system is reviewed and analyzed. Firstly, the construction principles and development steps are introduced. Secondly, the general realizations of signal frequency and the coordinate system as well as the time system of Beidou satellite navigation system in the frame of compatibility and interoperability are described. Thirdly, in the concept of redundancy, the main contributions of Beidou system are analyzed. At last, the applications and the main challenges of Beidou system are reviewed.
