天刚亮，聂帅和同事们就已经收拾好行囊，准备出发了。 聂帅所说的卫星，叫天通卫星，是我国构建空天地海一体化网络的重要支撑。这次来阿里，就是为了排查卫星的信号强弱。 央视网消息（新闻联播）："十五五"规划建议提出，前瞻布局第六代移动通信，核心是构建空天地海一体化网络。当前的一项重要工作，就是推动天通卫星 信号实现更好覆盖。春节前夕，总台《新春走基层》记者跟随中国电信卫星工程师，前往西藏阿里地区展开信号测试。 但让人没想到的是，等车开到了测试的峡谷，小雪花已经变成了密集的雪粒。 按照流程，找不到卫星信号，就要和北京监控中心取得联系，让北京调整信号强度，聂帅他们再进行检测。但是眼下，峡谷里既没有卫星信号，也没有手机 信号，雪还越下越大，聂帅权衡再三，决定还是先到有手机信号的地方对接北京。 漫天风雪中，车灯只能照到前方三五米，原本一小时的路程，足足开了两个半小时才抵达峡谷附近。 天气预报显示今天多云，晚些时候还会有小到中雪，这样的气象条件适合检验卫星信号。 在这个罕见的暴风雪夜晚，这场天通卫星的测试顺利结束。按照计划，小团队在这里短暂休息后，将赶往下一个测试的地方，继续追寻信号的踪迹。 调整需要一个小时，可就在这个期间 ...
