Enlightenment for the Development of Foreign Satellite Laser Communication Technology

摘要

Due to the military and commercial demands, space activities have become more frequent, and the exploration of the space around the world has been accelerating. The demand for high-speed data communications has prompted the development of satellite laser communication technology. Satellite laser communication has the advantages of large communication capacity, low transmitting power, long transmission distance, strong anti-electromagnetic interference capability and high security, which makes it gradually become an important direction for the development of space backbone network. Satellite laser communications terminals continue to become miniaturized volume, light weight and low power consumption, which makes it possible for small satellites applying laser communications technology. This paper introduces the development history and latest research progress of satellite laser communication in foreign countries, and the development status of domestic satellite laser communication, and summarizes some inspirations for the development of satellite laser communication technology.
