北斗三号全球定位系统启动建设:中国的北斗 世界的北斗

2017-09-17 10:51:40   中国青年网

央视网消息 :北斗卫星导航系统目前已经覆盖了亚太地区,目前正处在全球组网阶段,到2020年将实现全球组网,行走的中国北斗也将逐步走向世界。

卫星导航、通信、遥感是航天技术运用的三个主要领域。在人们日常生活和国民经济建设当中,总需要不断地问“在哪里”“什么时间”两个问题,人类90%以上的信息都与时间、空间相关。卫星导航技术的作用就是给人类提供时间坐标和空间坐标。时空信息深入到人类生产生活的各个领域,跟用水用电一样不可或缺,是国民经济的重要基础设施。就像停水停电影响城市生活一样,卫星导航服务一旦失效,国家的经济运行就要受到很大的影响。在日常的运作中,天上的卫星也有可能出现这样那样的毛病,影响到地面的导航服务。因而,中国需要掌握自主、独立、可控的卫星导航技术。

孙家栋院士认为,我国在导航系统领域,鼓励各国多系统共用,但在一些关键领域要坚持自主可控,这是未来导航系统发展的必然趋势。
