北斗卫星导航系统（以下简称北斗系统）是中国着眼于国家安全和经济社会发展需要，自主建设、独立运行的卫星导航系统，是为全球用户提供全天候、全天时、高精度的定位、导航和授时服务的国家重要空间基础设施。
The BeiDou Navigation Satellite System (hereinafter referred to as the BDS) has been independently constructed and operated by China with an eye to the needs of the country’s national security and economic and social development. As a space infrastructure of national significance
the BDS provides all-time
all-weather and high-accuracy positioning
navigation and timing services to global users.
20世纪后期，中国开始探索适合国情的卫星导航系统发展道路，逐步形成了三步走发展战略：2000年年底，建成北斗一号系统，向中国提供服务；2012年年底，建成北斗二号系统，向亚太地区提供服务；计划在2020年前后，建成北斗全球系统，向全球提供服务。
In the late 20th century
China started to explore a path to develop a navigation satellite system suitable for its national conditions
and gradually formulated a three-step strategy of development: to plete the construction of the BDS-1 and provide services to the whole country by the end of 2000; to plete the construction of the BDS-2 and provide services to the Asia-Pacific region by the end of 2012; and to plete the construction of the BDS and provide services worldwide around 2020.
随着北斗系统建设和服务能力的发展，相关产品已广泛应用于交通运输、海洋渔业、水文监测、气象预报、测绘地理信息、森林防火、通信时统、电力调度、救灾减灾、应急搜救等领域，逐步渗透到人类社会生产和人们生活的方方面面，为全球经济和社会发展注入新的活力。
Along with the development of the BDS project and service ability

– The first step is to construct the BDS-1 (also known as BeiDou Navigation Satellite Demonstration System). The project was started in 1994
and the system was pleted and put into operation in 2000 with the launching of o Geostationary Earth Orbit (GEO) satellites. With an active-positioning scheme
the system provided users in China with positioning
timing
wide-area differential and short message munication services. The third GEO satellite was launched in 2003
which further enhanced the system’s performance.
——第二步，建设北斗二号系统。2004年，启动北斗二号系统工程建设；2012年年底，完成14颗卫星（5颗地球静止轨道卫星、5颗倾斜地球同步轨道卫星和4颗中圆地球轨道卫星）发射组网。北斗二号系统在兼容北斗一号技术体制基础上，增加无源定位体制，为亚太地区用户提供定位、测速、授时、广域差分和短报文通信服务。
– The second step is to construct the BDS-2. The project was started in 2004
and by the end of 2012 a total of 14 satellites – 5 GEO satellites
5 Inclined Geosynchronous Satellite Orbit (IGSO) satellites and 4 Medium Earth Orbit (MEO) satellites – had been launched to finish the space constellation deployment. Based on a technical scheme which was patible with the BDS-1
the BDS-2 added the passive-positioning scheme
and provided users in the Asia-Pacific region with positioning
velocity measurement
timing
wide-area differential and short message munication services.
——第三步，建设北斗全球系统。2009年，启动北斗全球系统建设，继承北斗有源服务和无源服务两种技术体制；计划2018年，面向“一带一路”沿线及周边国家提供基本服务；2020年前后，完成35颗卫星发射组网，为全球用户提供服务。
