中美欧卫星互联网,“太空大战”愈演愈烈
3 6 Ke· 2025-06-11 09:03
卫星互联网"太空大战"愈演愈烈! 随着以Starlink(星链)为代表的低轨卫星互联网热潮兴起,马斯克对这项"历史规则"表达了不满。尤其是在宣布推出手机直连卫星(DTC)服务后,他 屡次寻求突破现有框架的机会。因为,若不突破现行规则对LEO卫星功率的限制,其手机直连卫星服务将仅限于短信文本,无法提供语音和数据上网功能 ——这自然是这位"科技狂人"所无法接受的。 在中国,低轨卫星互联网星座建设稳步推进。"千帆星座"目前已成功完成五个批次的组网卫星发射,标志着其部署工作全面进入常态化发射组网阶段。同 时,由中国星网集团牵头打造的"GW星座"也在不久前完成了卫星互联网低轨03组卫星的发射任务,实现了项目的第三次密集部署。 美国同样动作频频。美国联邦通信委员会(FCC)近日宣布,计划释放超过20000MHz的频谱资源,这一规模甚至超越了当前卫星系统可用的全部频谱总 量,以支持低轨卫星(LEO)和下一代卫星宽带服务的发展。在此之前,FCC还启动了一项旨在改变已有几十年历史的卫星功率限值的行动,推动低轨卫 星互联网覆盖更完善、范围更广。 另外,欧盟在去年底也宣布将斥巨资打造自己的卫星互联网系统。全球主要经济体正加速布局卫 ...

美媒:与中国的北斗系统脱钩是短视行为

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]

Core Insights - SpaceX's Starlink project aims to create a global satellite broadband network with thousands of low Earth orbit satellites, but recent satellite falls have raised concerns about the impact of solar activity on these satellites [1][5][11] Group 1: Solar Activity and Satellite Operations - Solar activity, particularly during the current solar cycle, has been linked to the recent falls of Starlink satellites, as solar storms can heat and expand the upper atmosphere, increasing drag on low-orbit satellites [1][3] - Low Earth orbit satellites, like those in the Starlink constellation, operate at altitudes between 160 km and 2000 km, making them more susceptible to atmospheric drag compared to higher geostationary satellites [3][7] - The drag effect on low-orbit satellites can lead to significant speed loss and eventual re-entry into the atmosphere, resulting in destruction [3][11] Group 2: Starlink Project Overview - The Starlink project is designed to provide high-speed internet access globally, with each satellite costing between $250,000 and $500,000 to manufacture [5][6] - Currently, there are over 7,000 Starlink satellites in orbit, with plans to expand this number to a maximum of 30,000 satellites by 2025, aiming for over 5 million users [6][9] - To achieve global coverage, a large number of satellites are required due to their limited coverage area and the need for continuous connectivity as they move rapidly across the sky [7][8] Group 3: Challenges and Future Considerations - The Starlink project faces challenges such as space debris management, international regulatory coordination, and the need for active collision avoidance strategies [9][10] - Despite its potential, Starlink is not expected to replace ground-based communication systems in the short term, as both technologies serve complementary roles in different environments [11] - From 2020 to 2024, a total of 583 Starlink satellites are projected to fall, with an increasing trend in the number of falls each year, highlighting the operational risks associated with solar activity [12][13]

Group 1 - The recent increase in the number of SpaceX's Starlink satellites falling from orbit has raised significant concerns, with a staggering 316 satellites expected to fall in 2024, a 259% increase compared to 2023 [2][6] - Since the launch of the Starlink project in 2019, the number of fallen satellites has escalated from 2 in 2020 to 78 in 2021, and 99 in 2022, totaling 583 satellites lost to date, which is approximately 1 in every 15 satellites [2][3] - NASA's research indicates a clear correlation between solar activity and satellite falls, with increased solar activity leading to atmospheric expansion that accelerates orbital decay for low Earth orbit (LEO) satellites [2][6] Group 2 - The Starlink project, initiated by SpaceX in 2015, aims to provide global internet access through a constellation of satellites, particularly targeting remote and rural areas [4] - The United States leads globally in the number of satellites in orbit, with 5,165 satellites as of May 2023, and accounted for nearly 50% of global launch attempts in 2023 [4] - SpaceX has not yet issued an official statement regarding the reasons behind the satellite falls, but studies suggest that stronger geomagnetic activity correlates with faster re-entry rates of satellites [6] Group 3 - The satellite falls have highlighted technical shortcomings in the Starlink project, raising discussions about space sustainability, the increase of space debris, and environmental impacts [3][6] - SpaceX claims that its satellites are designed to burn up upon re-entry, but actual cases have shown exceptions, posing potential threats to ground safety [3] - The limited thrust of the ion thrusters used in Starlink satellites makes it challenging to maintain stable orbits, contributing to the increased risk of satellite falls [3]
马斯克星链卫星大批坠落!
证券时报· 2025-06-10 08:51
近日,美国企业家马斯克的太空探索技术公司(SpaceX)发射的星链(Starlink)卫星接连坠落,引发外界关注。分析认为,太阳活动或是主要原因。 星链卫星(图片来源:星链官网) 星链卫星大批坠落 最近,一份由美国马里兰大学和美国航空航天局(NASA)戈达德航天中心联合发布的一项研究指出,由于当前太阳活动加剧,星链卫星正在比预期更快地坠入地 球大气层。 研究团队通过分析2020年至2024年间523颗星链卫星的轨道数据,发现了一个令人担忧的趋势:在强烈的地磁风暴期间,这些卫星坠落地球大气层的速度远超预 期。研究人员表示:"我们的结果无可争议地表明,地磁活动越强,卫星坠落的速度就越快。" 针对这一现象,由美国国家航空航天局(NASA)戈达德航天中心的物理学家丹尼·奥利维拉领导的研究小组分析认为,卫星坠落与太阳活动存在明确关联。 研究报告指出:"我们清楚地发现,当前太阳活跃度的增强对星链卫星坠入大气层产生了显著影响。这是一个研究卫星轨道阻力的绝佳时期,因为在本轮太阳活动高 峰期,地球低轨卫星的数量达到了人类历史上的最高水平。" 星链卫星的发射始于2019年,当时处于太阳活动的低谷期。NASA的统计显示,去年是太阳 ...
