“成功登顶！”5月23日，2023年珠峰科考13名科考登顶队员成功登顶珠穆朗玛峰，这是中国珠峰科考继2022年之后再次突破8000米以上海拔高度。

中国登山者无惧风雪、不懈攀登，这其中离不开一系列国产“黑科技”的加持，彰显出中国加强自主创新、加大知识产权保护力度带来的强大底气。

“硬核”科技护航冲顶

在冲顶过程中，把握海拔6000米至9000米不同高度层上的风和雪至关重要。

为了给科考队提供一路护航的气象服务，此次冲顶过程中，轻量型实时卫星应用服务平台——“风云地球”平台的使用，补全了特殊地形下的气象监测空白。该平台是中国国家卫星气象中心自主研发的一大成果，旨在运用天地一体化的智能观测与控制技术等，将云图产品服务延迟控制在分钟级，强化风云气象卫星在气象核心业务中的支柱作用。据了解，围绕风云气象卫星及相关应用，该中心已经提交了“一种风云气象卫星协同多数据源的三维云融合分析的方法”等多件专利申请，助推卫星遥感应用服务质量提升。

透过央视新闻的直播画面，中国乃至全世界的观众同步见证了科考队再次登顶的辉煌时刻，这其中得益于上海通维数码科技有限公司（下称通维数码）在前向纠错等直播前沿技术领域的专利布局和在多平台直播方案方面的经验积累。通维数码利用5G直播背包回传直播关键机位信号，并将登顶队员的第一视角画面通过手机直播应用程序实时采集并回传至中央广播电视总台北京总部，实现登顶珠峰实况全程直播。

自主创新助力科考

登顶不是唯一目标，科考任务使命在肩。早在2022年5月，中国科考队员就在珠峰北坡海拔8830米处，架设了世界上海拔最高的自动气象站，填补了中国珠峰地区极高海拔气象观测记录的空白。今年，对自动气象站进行维护与技术升级，是珠峰科考的重要任务之一。

天气变化快、风力大、气温低——珠峰极高海拔区域严峻的环境对自动气象站的运行带来极大考验。为进一步解决仪器设备供电面临的极低温、极低压等“卡脖子”问题，今年，科考队和负责探月工程供电系统的研究人员合作将月球上供电系统技术应用到极高海拔地区。其中，贵州梅岭电源有限公司（下称梅岭电源）专门为自动气象站供电配套的低温光伏储能系统发挥了重要作用。针对极低温、极低压等技术难题，梅岭电源快速组建联合研发团队，利用储备的深空探测电源技术，推动相关产品在野外环境实现自主充电。据了解，梅岭电源近年来在电源系统、方舱储能系统等关键核心技术领域的多件专利申请获得授权，相关电源产品在“神舟”飞天、“嫦娥”奔月等中国重大航天任务中落地应用。

截至目前，科考队已顺利完成雪冰样品采集、冰芯钻取等十多项既定科考任务。通过新技术和新手段的应用，中国珠峰科考正在从“登山科考”转向“科考登山”，实现从“攀登”到“了解”再到“保护”的思路转变。

如今的珠峰之巅，不仅闪耀着中国科技创新的光芒，还见证了中国科考队员不畏艰险、勇攀高峰的精神和勇气，向全世界人民带去鼓舞。（苏悦）
