Title: System for determining precise orbit of satellite and method thereof

Abstract: 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 L1 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 L1 carrier phase data collected by a satellite, L1/L2 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.
