Abstract

Due to the limitation of satellite payload performance and the influence of space environment, large-capacity information transmission between satellites has always been a key difficulty in the field of inter-satellite information transmission. Laser communication has the characteristics of fast transmission rate and large information capacity, which is very suitable for large-capacity inter-satellite information transmission. This article introduces the related concepts of laser communication, investigates the development status of space laser communication and laser communication relay system, briefly introduces the representative laser communication satellite system, and summarizes the advantages and disadvantages of laser communication. The inter-satellite laser communication relay system is designed based on two different application scenarios. The inter-satellite distance and information transmission window are simulated based on the SGP4 model to verify the feasibility of the relay system to extend the inter-satellite laser communication. The engineering realization of the follow-up system has a certain meaning.
