Abstract
In this thesis, we realized tracking system for the purpose of receiving performance improvement of KOREASAT's signal in Korea peninsula. Using Scan-mode antenna point out receivable area without position information sensor and using step-track algorithm reach to peak level. Furthermore, the performance of the completed system was verified by physical experiments that directly receives satellite signal. And decided the optimal size of steps for tracking speed and structure of the system by reiterative approach experiments.
