服务|手可摘星辰 | 掌控北斗“脉搏” 这支“天团”正青春！_卫星导航系统|原子钟|节拍|星

<br />文章图片 <br /> <br /> 北斗卫星导航系统作为事关国计民生的大国重器，其中有一支“湖南力量”功不可没，那就是北斗三号卫星导航系统建设的核心主力——国防科技大学北斗卫星导航科研团队。今天，我们就走进国防科技大学导航中心，走近这支正青春的“北斗天团” 。<br /> 国防科技大学电子科学学院导航中心某研究室主任、副研究员龚航： <br /> <br /><img

这就是通过北斗授时获得的时间，目前北斗系统时间精度可以做到几百万年偏差一秒。在通信、电力、金融方面为国民经济、国防提供服务。<br /> <br /><img alt="服务|手可摘星辰 | 掌控北斗“脉搏” 这支“天团”正青春！" onload="javascript:ImgReSize(this)"

时间频率作为时间基准，精度越高，就能带来更高性能的服务。就像人类跳动的脉搏，没有它，卫星导航系统就无法正常运转。而让北斗的“脉搏”跳动起来的，就是国防科技大学北斗卫星导航科研团队。<br /> <br /><img alt="服务|手可摘星辰 | 掌控北斗“脉搏” 这支“天团”正青春！" onload="javascript:ImgReSize(this)"

为了让这个“节拍”更好地支撑系统服务，北斗三号时频系统设计了一种全新的技术体系架构，在完全自主可控的情况下，不仅大大提升传输距离，时间同步精度也提升了一个量级。去年7月31号，北斗三号全球卫星导航系统正式开通。这支平均年龄30出头的青年团队就贡献了不少智慧，试验阶段，项目组实行24小时“三班倒” ，模拟各种可能出现的故障场景，都一一攻关。<br /> <br /><img

目前北斗系统地面系统稳定运行，在这个场地我们做了非常重要非常关键的测试验证的工作，才能装到站里去。我们基于全国产原子钟组，加上自主设计的高精度综合原子时的算法，实现整个北斗时间基准的准确度和稳定度都提升了一个量级。</p> <div class="dede_pages"><ul><li><a href='#'>上一页</a></li><li class="thisclass"><a
