Abstract
"Nowadays, earth stations for downloading data from LEO (Low Earth Orbit) satellites use large reflector antennas. These antennas pose a number of impairments; furthermore, reflector antennas can track only one satellite at a time, so the efficiency of the earth segment is reduced. In order to improve the performance of traditional earth stations the feasibility of other antenna technologies must be evaluated, such conformal adaptive antennas based on multiple planar arrays like geodesic antenna array (GEODA). This antenna has several advantages over large dishes and the efficiency to track several satellites simultaneously is a function of the number of antenna elements, beamforming algorithm and the correct calibration of the antenna arrays. In this paper a brief introduction of the developing of the new generation of earth station is presented."
