Aiming at the shortage of space information transmission capacity of existing radio methods,in this paper the advantages of space laser communication is briefly analyzed,the development status and plan of space laser communication at home and abroad are emphatically introduced,and the future development trend of space laser communication is studied. Aiming at the development trend of satellite miniaturization and networking,a space laser communication and networking method based on retro-reflector modulation technology was proposed.Combined with the development status and insufficient of space laser communication in China,the key technologies in related fields are summarized and analyzed.
