Design of FCS for Satellite Constellation

With the rapid development of commercial aerospace, the number of satellites is increasing every year. While focusing on satellite manufacturing, the demand for satellite on-orbit operation management is also increasing. To meet the increasing requirements of satellite on-orbit operation management, this paper presents a design of FCS (Flight Control System) for satellite constellation. Starting from the system architecture, it describes the front-end design of the ground station, the design of the cloud data center and the design of user center, and gives the telemetry and telecommand data flow. Using the proposed system design in this paper, the full link and high-efficiency real-time processing of satellite on-orbit management can be realized, which is more in line with the development trend of commercial satellite industry.
