Core Insights - The satellite internet industry is rapidly evolving, with low Earth orbit (LEO) satellite systems emerging as the preferred choice due to their advantages in transmission delay, link loss, launch flexibility, diverse application scenarios, and lower manufacturing costs [1][10][18]. Industry Overview - Satellite internet is a hot topic in satellite communication, with a promising development outlook. It utilizes satellite transponders for communication between ground stations, differing from traditional cellular communication [1][10]. - The global satellite industry is projected to grow, with an estimated market size of $308.3 billion in 2023, reflecting a year-on-year growth of 4.5% [20][21]. Competitive Landscape - Countries are engaged in a race to deploy LEO satellites, with China planning to launch over 26,000 satellites as part of its national strategy [1][29]. - Major international players include SpaceX's Starlink, OneWeb, and Telesat, while domestic companies like China Satellite Network Group and Shanghai Yuxin Satellite Technology are also making significant strides [29][32]. Industry Chain Structure - The satellite internet industry chain consists of four main segments: satellite manufacturing, satellite launching, ground equipment, and operations/services [1][34]. - In satellite manufacturing, the costs of payload and platform each account for 50% of the total, but this can decrease to 30% or even 20% with mass production [34]. Ground Equipment and Services - Ground equipment has become increasingly valuable, accounting for 52% of the global satellite industry chain by 2022, reflecting a rising trend in its importance [23]. - Satellite services are highly regulated, requiring operational licenses from the Ministry of Industry and Information Technology in China [1][34]. Technological Advancements - Phased array antennas are critical for LEO satellite communication, offering advantages over traditional mechanical antennas, such as multi-beam forming and strong anti-jamming capabilities [2][10]. - The development of high-throughput satellite technology is enhancing communication capabilities and reducing costs, making satellite internet more accessible [19].
