许丰娜：中国一次申报20万颗卫星意味着什么

Core Viewpoint - China's recent submission to the International Telecommunication Union (ITU) for frequency and orbital resources for 203,000 satellites marks the largest international frequency and orbit application in the country's history, reflecting China's commitment to sustainable global space development [1] Group 1: Satellite Resource Application - The application covers 14 satellite constellations and is a strategic move within the framework of international space regulations, emphasizing China's adherence to the Outer Space Treaty [1] - The low Earth orbit (LEO) and frequency resources are highly sought after due to their performance advantages and scarcity, with estimates suggesting that only about 60,000 satellites can be accommodated in near-Earth orbit [2] - SpaceX's Starlink has a significant lead with over 9,000 satellites in orbit, accounting for nearly 60% of the global LEO satellite count, which poses safety challenges for other nations [2] Group 2: Deployment and Manufacturing Capabilities - The number of 203,000 satellites does not equate to the actual deployment quantity, as large-scale early applications are common in global LEO satellite development [3] - China's space industry is supported by innovations across the entire supply chain, including breakthroughs in reusable rocket technology and satellite manufacturing, significantly reducing production times [4] - The country has the capacity to support large-scale satellite networking ambitions, with a focus on sustainable development in space as LEO resources approach saturation [4] Group 3: Space Governance and Safety Measures - China is taking proactive measures to address space debris and collision risks, including the design of satellites with deorbiting devices and the initiation of collision warning systems [5] - The country firmly opposes the militarization of space, focusing its satellite constellations on civilian applications such as communication, remote sensing, and navigation [5] - China advocates for a "community of shared future in space," proposing new governance frameworks for equitable resource distribution and emphasizing cooperation over competition in space development [6]
