| 摘 要： | 从PNT(定位、导航、授时)系统工程的视角介绍北斗卫星导航系统的进展和未来。北斗系统有开放服务和授权服务两种业务;开放服务免费提供定位(精度为10 m)、测速(精度为0.2 m/s)、授时(单向精度为50 ns)和短电文(120字/次)通信服务;授权服务将向授权用户提供更安全、精度更高的定位、导航(测速)、授时和通信服务以及系统完好性信息。该系统具有开放性、自主性、兼容性、渐进性等特点;它能为中国的电信网、电力网、广播电视网、计算机网提供高精度时间频率同步,并为渔业、交通运输、军事、地震、气象、科技工程诸等多领域提供各种PNT应用;有必要指出,北斗系统是中国PNT业务的核心和应用产业平台。
