- Abstract
- The so-called real-time system, which controls the satellite by sending telecommands and monitors the satellite from receiving the telemetry, is a system dependent on the satellite. The flight software running on the satellite's onboard computer and the satellite database affect a large part of the functionality that the real-time system must have. Therefore, most satellite production companies have created a ground control system that can operate their own satellites, or they are supplying it through cooperation with external organizations. However, the satellite operators have to endure an inconvenience and operational burden to use a satellite control system with new features, new user interface, and new operation concept whenever the supplier of satellites is changed. To solve this problem, even if the satellites change, a real-time system with the same user interface and operation concept should be available with only minimal customization. Electronics and Telecommunications Research Institute (ETRI) in Korea has implemented a core software platform that can be used again for other satellite and developed a real-time system running on it. Therefore, a real-time system for various satellites can be constructed using minimal customization and conversion tools and the results were applied to a real-time system for operating Koreasat-7 launched in May 2017.In this paper, we describe the implementation of core software platform and the results of the real-time system development through customization, and introduce the real-time system of Koreasat-7 to be operated by it.
