- Abstract
- 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. The SGCS for communication, ocean, and meteorological satellite (COMS) is currently being developed in Korea, which is implemented to satisfy high availability, expansibility, and compatibility in design. In order to implement the system architecture to meet these characteristics, this paper introduces the concept of the real-time distributed system structure based on fault detection and recovery, data replication and sharing using CORBA middleware and redundancy scheme. This paper also describes down-sized hardware and software configuration to perform the mission operation of geostationary satellite, and the prototyped services for 24-hour operation SGCS assuring high availability is presented in detail
