Core Viewpoint - The article discusses the implications of China's BeiDou satellite navigation system, arguing that it is not a weapon but a critical technology that enhances global navigation reliability and precision, and that the U.S. risks national security and economic competitiveness by limiting access to it [1][2][3] Group 1: Technology and Security - The BeiDou system is a competitor to GPS and has raised suspicions among U.S. officials, leading to investigations by the Federal Communications Commission [1] - Limiting access to BeiDou could weaken the resilience of Positioning, Navigation, and Timing (PNT) systems, ultimately harming U.S. national security and commercial operations [1] - Tests indicate that disabling BeiDou could reduce positioning accuracy by 30% to 40%, significantly impacting navigation, logistics, and emergency services [1] Group 2: Economic Impact - Precision positioning is foundational for key industries such as logistics, agriculture, aviation, and automation; excluding foreign satellite navigation systems could lead to increased costs, deployment delays, and reduced competitiveness for U.S. companies [3] - China is likely to continue forming partnerships with countries seeking open and reliable navigation services, which could further enhance its influence in international technology standards [3] - The BeiDou system is viewed as a tool for soft power rather than a weapon, contradicting claims that it could be used as an active warfare tool [3]

没有目的，就做不成任何事情。目的渺小，就做不成任何大事。 ——狄德罗 # 我科学家领衔研究团队首次利用TTV技术在类太阳恒星宜居带发现"超级地球" 可能存在碳基生命 中国科学院云南天文台研究员顾盛宏领衔的国际联合研究团队，近期利用凌星中间时刻变化（TTV）反演技术，首次在类太阳恒星的宜居带内发现一颗质 量约为地球10倍的超级地球——开普勒725c。北京时间3日下午，国际期刊《自然·天文》发表了这一突破性成果。 开普勒725c所围绕的是一颗G9V型恒星，与太阳光谱型相似，但年龄仅16亿年，磁场活动比太阳剧烈。该行星公转周期约为207.5天，与地球公转周期相 近，且位于可存在液态水的宜居带内，具备类地生命存在的条件。 这项发现，一方面为探测系外地球提供了新途径，使TTV反演技术成为发现类太阳恒星宜居带中"隐形行星"的有力工具；另一方面，为我国未来的空间天 文任务，如中国载人航天工程巡天空间望远镜（CSST）、地球2.0（ET）项目等，提供了新的观测目标和探测技术支持。 # 工业和信息化部为新型气象探空系统提供频谱资源保障 我国自主研发的P频段北斗卫星导航新型气象探空系统于2024年7月完成第一阶段建设任务，经一年 ...

Core Viewpoint - The recent statement by U.S. Secretary of State Rubio highlights the limited influence the U.S. has over China's internal affairs, acknowledging the failure of past U.S. interference policies towards China [1][4]. Group 1: U.S.-China Relations - Rubio's comments reflect a recognition of the ineffectiveness of U.S. attempts to influence China's development through various means, including political criticism, trade wars, and cultural interventions [1][3]. - The trade war initiated during Trump's administration serves as a prime example of U.S. failure, as it quickly led to negotiations rather than the intended concessions from China [3][6]. - U.S. technology restrictions aimed at hindering China's tech development have not deterred Chinese companies, which have instead increased their investment in R&D and achieved significant advancements [3][6]. Group 2: Domestic Political Reactions - Rubio's statement has sparked significant backlash within U.S. domestic politics, particularly from Democrats who question his capabilities as Secretary of State [4][6]. - The division between the two major political parties in the U.S. regarding China policy reveals a lack of coherent strategy in addressing China's growing influence [6][9]. Group 3: Economic Context - China's robust domestic market and manufacturing capabilities position it as a critical player in global supply chains, contrasting with the U.S. challenges of industrial hollowing and debt crises [9]. - The U.S. is urged to abandon its confrontational economic policies towards China, as continued opposition may harm its own economic interests [9].

1975年，我国首次将一个高3．5米的红色金属测量觇标矗立于珠峰之巅；2005年，珠峰测量首次采用卫星大地测量技术和雪深雷达测 量技术，首次获得了珠峰岩面高程；2020年，北斗卫星和国产测绘装备担纲主力，我国首次在珠峰地区开展航空重力测量，并将重力测量 推到顶峰。 新中国成立之初，中央人民政府提出了"精确测量珠峰高度，绘制珠峰地区地形图"的要求。1966年，我国珠峰高程测量拉开帷幕。 1966年～1968年，国家两次组队在珠峰地区建立了高质量的平面坐标和高程控制网，开展三角、水准、天文、重力等测量工作，为此后的 珠峰高程测量奠定了坚实基础。 "目前为止，我国官方珠峰高程测量共开展了三次，分别在1975年、2005年和2020年，这三次珠峰测量也都是测量技术发展的代表性台 阶。"2020珠峰高程测量技术协调组组长、中国测绘科学研究院首席研究员党亚民说。 1975年珠峰高程测量是中国首次自主完成的珠峰精确测量。测量队员把大地控制网推向珠峰北麓，并在北坳完成了海拔7050米处的重 力测量和航测调绘任务。5月27日，登山测量队员在珠峰顶峰设置了测量觇标——这是人类历史上首次将觇标带到珠峰峰顶。当时精确测得 珠峰海拔高 ...

Core Viewpoint - The article commemorates the 50th anniversary of China's first independent measurement of Mount Everest's height, highlighting the significance of accurate height measurement for international standards and environmental monitoring [1][3]. Measurement Process - The precise determination of Mount Everest's height aims to resolve the inconsistencies in international height data, providing essential information for glacier monitoring and ecological studies [3]. - The 2020 measurement utilized a global elevation benchmark agreed upon by China and Nepal, incorporating gravity measurements and advanced satellite data to create a high-precision gravity field model of the Everest region [3][5]. - The measurement involved a team of climbers establishing a benchmark at the summit, with simultaneous triangulation and intersection measurements conducted from six reference points at the mountain's base [4]. Technology and Equipment - The climbers employed Beidou satellite navigation signals for accurate positioning and used ice and snow radar to measure the thickness of the snow layer at the summit [5]. - The measurement process required human presence due to the extreme conditions at the summit, which rendered helicopters and drones ineffective for stable operation [8][11]. Climatic Conditions - The measurements have historically been conducted in May, as this month offers a brief window of relatively stable weather conditions, avoiding the harsh winds and precipitation typical of other months [12][13]. - The peak's summit area is limited in size, making helicopter landings impractical, and the measurement equipment necessitates direct human operation to ensure accuracy [11][14].
