Disclosed is a command planning apparatus of a low-earth orbit satellite, and a low-earth orbit satellite control system including the same. The present invention automates the process of executing the command plan for converting the satellite task schedule planned on the ground into telecommands available by the satellite in the low-earth orbit satellite control system, and automatically selects a data set established by the parameters related to the execution task of the satellite according to the mapping rule.

Low earth orbit satellite command planning device and method, and low earth orbit satellite control system including the same

In a system for determining a precise orbit of a satellite, a satellite control system includes a tracking, telemetry and command module for receiving telemetry data from the satellite, tracking the satellite, and performing link to the satellite; a satellite operations sub module for extracting L carrier phase data by processing the telemetry data, monitoring the satellite, generating telecommand data, and controlling the satellite; and a mission analysis and planning subsystem for determining the precise orbit of the satellite using the L carrier phase data collected by a satellite, L L carrier phase data of the reference ground stations of the GPS satellites collected by an IGS, and a path error caused by the ionosphere of data, and analyzing and planning a mission of the satellite.
