Research on satellite-to-ground laser communication system and business process

Recently with the massive explosion of remote sensing observation satellites and the deployment of low earth orbit (LEO) broadband communication satellites, the demand for data transmission of data relay satellites has increased sharply. Higher and higher capabilities have been proposed for data relay satellites. However, the current situation is the limited on-board storage capacity, the low microwave link rate. In view of the huge amount of data produced by various medium and low orbit vehicles, a satellite-to-ground laser communication application system is constructed based on the analysis of domestic and foreign relay satellite systems. The overall business process is also researched of this laser communication application system, from customer satellite resource application, link control to data return. Then the subsequent work is prospected.
