Earth Station Tracking SIGSO Satellite: Analysis and Discussion
Earth station and satellite are important components of the satellite communication system, this paper analyses earth station antenna for the main measurement parameters, which include azimuth, elevation, satellite to the ground distance and AGC of beacon signal; explores the earth station antenna AGC servo tracking system; azimuth, elevation and AGC level value are calculated when the earth station in Peking aligns APstar-1 satellite. Experimental results show that the changing amplitude of azimuth, elevation and APstar-1satlellite drifts rate is increasing in the past years.
