According to a research report from CITIC Securities, since November, the pace of China's domestic low-orbit satellite network construction has picked up significantly. Satellite payloads represent the technological heart of satellite networking communication capabilities. Within this framework, the "inter-satellite laser link" plays a pivotal role in facilitating data transmission between satellites. Compared to traditional microwave communication, this technology offers a significant upgrade, boasting high technical barriers and serving as a critical enabler for transforming space computing power from a conceptual idea into a practical, deployable reality. As the satellite fleet expands, individual satellite computing capabilities enhance, and satellite network complexity rises, the strategic importance of inter-satellite laser links will become even more pronounced. It is advisable for investors to keep a close eye on leading companies in the payload sector.
