国盛证券：激光通信或为商业航天新一代“核心基建” 关注产业规模化部署与成本突破

Core Viewpoint - The development of inter-satellite and satellite-to-ground high-speed communication technology using lasers is rapidly advancing, becoming a key direction for future space information networks due to its ability to provide greater communication capacity [1] Group 1: Definition of the New Era - Laser communication is an indispensable new cornerstone for low Earth orbit (LEO) constellations, as it offers high brightness, strong directionality, and excellent monochromaticity, making it an ideal communication medium [1] Group 2: Technical Mechanism - Satellite internet utilizes lasers to construct a high-speed "information highway" between satellites, requiring each satellite to connect with four surrounding satellites, with dynamic link establishment necessary for satellites in different orbital planes [2] Group 3: Application Blueprint - Laser communication enables the construction of a global "space-based Wi-Fi," providing broadband coverage and low-latency communication, and connecting land, sea, air, and space into a real-time responsive intelligent network [3] Group 4: Industry Competition - The domestic laser communication industry faces a dual competition against time and international rivals, with a significant market opportunity worth hundreds of billions, driven by the need for large-scale deployment and cost breakthroughs [4] Group 5: Investment Recommendations - Focus on six companies within two camps: 1. National Camp: Core suppliers benefiting from top-level planning and stable demand, including Aerospace Electronics, Guobo Electronics, and Fenghuo Communication [5] 2. Private Camp: Innovative companies with high elasticity and vitality, including Shanghai Hanxun, Zhenlei Technology, and Chengchang Technology [6]
