【摘要】 北斗卫星导航系统是我国自主规划、设计、建设与应用的高技术项目的一面旗帜。2020年6月23日，北斗系统最后一颗组网卫星发射成功。7月31日，总书记习近平出席北斗三号全球卫星导航系统建成暨开通仪式，并宣布正式开通。本文梳理了中国卫星导航的发展历程，分析了自主卫星导航系统决策的背景、北斗系统各阶段建设过程中体现的特点，重点探讨了北斗系统“三步走”发展战略的形成过程及创新之处。在简述北斗系统建设过程后，对北斗系统发展中体现的工程与技术创新进行初步探讨。更多还原

【Abstract】 The BeiDou Navigation Satellite System(BDS) is a flagship high-tech project of independent planning, design, construction and application in China. On June 23, 2020, the last BDS satellite was successfully launched. This paper reviews the development history of satellite navigation systems in China, analyzes the decision-making background of the autonomous satellite navigation system, analyzes the characteristics reflected in the construction process of the BDS at each stage, and focuses on the formation process and innovation of the “three-step” development strategy of the BDS. After a brief introduction to the BDS construction process, the paper provides a preliminary discussion on the engineering innovation and technological innovation embodied in the development of BDS.更多还原
