Core Viewpoint - The recent surge in interest surrounding satellite internet in China is driven by two main events: the rapid deployment of satellites by China Star Network and the anticipated issuance of satellite internet licenses to major telecom operators [1][19]. Group 1: Satellite Internet Development - China Star Network has accelerated its deployment of satellites, launching 38 satellites in 21 days, indicating a significant increase in the pace of its GW constellation deployment [1]. - The anticipated issuance of satellite internet licenses could include major players such as the three major telecom operators, China Star Network, and Shanghai Yuxin [1][26]. - The current landscape for satellite internet is challenging, with a low probability of success due to high costs and technical difficulties associated with low Earth orbit (LEO) satellite constellations [3][10]. Group 2: Historical Context and Technological Challenges - The development of satellite communication in China began in earnest after the Wenchuan earthquake, leading to increased investment in satellite communication technologies [4]. - China's first high-throughput satellite, Zhongxing 16, was launched in 2017, with subsequent satellites achieving higher capacities, such as Zhongxing 26, which has a capacity exceeding 100 Gbps [5]. - The operational logic and technology of LEO constellations differ significantly from medium and high orbit satellites, requiring a large number of satellites for global coverage [8][9]. Group 3: Economic and Strategic Considerations - The cost of maintaining a LEO constellation is substantial, and commercial viability is crucial for sustaining operations, especially given the need for continuous satellite replenishment [10][18]. - The establishment of China Star Network is partly driven by the need for a domestic satellite constellation, similar to the Beidou system, to enhance national capabilities in satellite communication [17]. - The demand for satellite communication is increasing due to the digital transformation of society and the need for coverage in remote areas, as well as for emergency and defense applications [14][15][16]. Group 4: Regulatory and Market Dynamics - The upcoming satellite internet licenses are linked to the first-class basic telecommunications business, indicating a move towards commercial operations in satellite internet [25]. - The three major telecom operators are unlikely to develop large-scale LEO constellations but may focus on specific services using medium and high orbit satellites [26]. - The success of domestic satellite constellations will depend on technological advancements, funding, and support from the national level and the industry chain [26].
