Investment Rating - The industry investment rating is "Outperform the Market," indicating an expected performance that exceeds the market by more than 5% over the next six months [20]. Core Insights - The low Earth orbit (LEO) satellite network is being established, and direct-to-device (D2D) satellite services will be crucial for the integration of space and ground communication. This service allows mobile phones to connect directly to communication satellites without intermediary devices, providing voice, text, and data exchange services [3][4]. - The report identifies three technical routes for mobile direct connection, with the 3GPP NTN standard recognized as the future direction. The three routes include: 1. "New Phone + Old Satellite" - integrating dedicated satellite communication modules into smartphones, relying on existing satellite systems [11]. 2. "Old Phone + New Satellite" - using existing mobile communication technology to connect current 4G/5G phones directly to satellites [11]. 3. "New Phone + New Satellite" - following the 3GPP NTN standard, creating new low Earth orbit constellations that work with ground 5G networks [11][9]. - The global mobile direct connection industry is advancing rapidly, with significant developments from international players like SpaceX and AST SpaceMobile. In January, a partnership between Globe Telecom and Starlink marked the launch of DTC services in Southeast Asia, covering approximately 4% of the population in areas without ground network coverage [14][16]. - The report emphasizes the importance of mobile direct connection satellites as a key entry point for connecting the general public to space-based networks, highlighting the expected growth in demand for phased array antennas, terminal communication chips, and modules [17]. Summary by Sections Industry Overview - The report discusses the ongoing establishment of low Earth orbit satellite networks and the role of mobile direct connection satellites in expanding communication capabilities, addressing gaps in ground network coverage [3][4]. Technical Routes - Three main technical routes for mobile direct connection are outlined, with the 3GPP NTN standard being the most promising for future development [9][11]. International Developments - Significant progress in the mobile direct connection sector is noted, with various international companies making strides in D2D technology and partnerships [14][16]. Investment Recommendations - The report suggests a strong outlook for the mobile direct connection satellite sector within China's commercial aerospace industry, recommending a focus on investment opportunities in this area [17].
