Abstract

Communication satellites in the geostationary orbits possess daily motion which causes the apparent position of the satellite to wander in the sky as seen by the earth station. If uncompensated, it will cause a variation in the performance of communication link. Therefore, the movement of the satellite has to be tracked by the earth station antenna. This reports aims to give an understanding of the satellite communication system and also the requirements in the alignment and tracking method of the earth station. In this report, we will explore the functions of communication system and its subsystems. The parameters in the link budget and earth station configuration will also be discussed. Other than that, the determination of the azimuth and elevation angles and slant range will be done in order to point the earth station to the satellite by using calculation and simulation method. Then, the results will be analyzed and compared. To conclude, the alignment and tracking is important to ensure reliable communication links between satellite and earth station.
