The Satellite Operation System (SOS) has been developed for a low earth orbiting remote sensing satellite, Korea Multipurpose Satellite‐I, to monitor and control the spacecraft as well as to perform the mission operation. SOS was designed to operate on UNIX in the HP workstations. In the design of SOS, flexibility, reliability, expandability and interoperability were the main objectives. In order to achieve these objectives, a CASE tool, a database management system, consultative committee for space data systems recommendation, and a real‐time distributed processing middle‐ware have been integrated into the system. A database driven structure was adopted as the baseline architecture for a generic machine‐independent, mission specific database. Also a logical address based inter‐process communication scheme was introduced for a distributed allocation of the network resources. Specifically, a hot‐standby redundancy scheme was highlighted in the design seeking for higher system reliability and uninterrupted service required in a real‐time fashion during the satellite passes. Through various tests, SOS had been verified its functional, performance, and interface requirements. Design, implementation, and testing of the SOS for KOMPSAT‐I is presented in this paper.
