Abstract:Under the background of the rapid development of laser communication technology and the urgent needs of commercial satellite networking applications, minisatellite laser communication technology is one of the research hotspots in the field of commercial satellite communication. First, the latest development status and performance index characteristics of minisatellite laser communication terminal technology at home and abroad are discussed in detail. Then, the four development trends such as lightweight and miniaturized, low power consumption, modular and low cost are summarized. Finally, four key technologies of minisatellite laser communication terminal are analyzed for promoting the development of China’s minisatellite laser communication
