A two-line element set (TLE) is a data format encoding orbital elements of an Earth-orbiting object for a given epoch. Using suitable prediction formula, the motion state of the object can be obtained at any time. The TLE data representation is specific to the simplified perturbations models, so any algorithm using a TLE as a data source must implement one of these models to correctly compute the state at a specific time. Accurately adjustment of antenna direction on the earth station is the key to satellite communications. With the TLE set topocentric elevation and azimuth direction angles can be calculated. The accuracy of perturbations models directly affect communication signal quality. Therefore, finding the error variations of the satellite orbits is really meaningful. In this present paper, the authors investigate the accuracy of the Geostationary-Earth-Orbit (GEO) with simplified perturbations models. The coordinate residuals of the simplified perturbations models in this paper can give references for engineers to predict the satellite orbits with TLE.
