For low-earth orbit satellites, ground station antenna control data calculated from orbit prediction have non-negligible error, mainly by uncertainty of atmospheric drag. Simple correcting method of antenna prediction error using acquisition data has been formulated. Model simulation shows that this method mitigate antenna direction error under 0.1deg, which is enough accuracy for tracking low-earth orbit satellite by X-band. More accurate antenna prediction data are expected for useful to protect radio interference from other satellites.
