It is the core of the satellite control mission to monitor the status information of the satellites for satellite operation and to transmit the commands necessary for operation. In the case of geostationary satellites, the real-time Mission Operation System required for the continuous monitoring system is indispensable because it acquires not only sensor data but also satellite status information from the satellite 24 hours a day, 365 days a year. In case of low orbit satellites, status information of satellites is acquired through TM data from overseas ground stations including domestic ground stations to monitor the operation status of satellites at all times.
