Nueva estación terrena para seguimiento de satélites LEO

Abstract

Since earth stations for downloading data from LEO (Low Earth Orbit) satellites use large reflector antennas has a number of impairments in terms of cost and mechanical complexity; 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 a number of advantages over large dishes and the efficiency to track several satellites simultaneously depends on the number of antenna elements, beamforming algorithm and the correct calibration of the antenna arrays. In this paper a brief introduction of the development of the new generation of earth station is presente.
