Model validation and analysis of antenna look angles of geostationary satellite

The performance of a satellite communications system can be optimized by pointing the direction of maximum gain of an earth station antenna (referred to as boresight) directly at the satellite. To ensure that an earth station antenna is aligned with the satellite, two angles must be determined: the azimuth angle and the elevation angle. These are the co-ordinates, look angles, to which an earth station antenna must be pointed in order to communicate with a satellite. This paper describes validation and analysis of the models of antenna look angles of geostationary communications satellite. Model validation was utilized in order to determine whether the models developed were accurate representations of the real system.
