A satellite ground control system (SGCS) that monitors and controls a geostationary satellite 24 hours a day has to achieve the distributed architecture assuring high-level availability and redundancy scheme. The SGCS for Communication, Ocean, and Meteorological Satellite (COMS) is currently being developed in Korea, which will be implemented to satisfy high availability, expansibility, and compatibility in design. In order to implement the system architecture to meet these characteristics, the SGCS introduces the concept of the real-time distributed system structure based on fault detection and recovery, data replication and sharing, and Fault Tolerant CORBA middleware. This paper describes each subsystem's hardware configuration and software function to perform the mission operation of geostationary satellite, and the duplicated and distributed architecture for 24-hour operation ground control system assuring high availability is presented in detail.
