摘要:An antenna pointing system automatically aligns an antenna with a geo-synchronous satellite using a Ku band signal, which has a relatively broad bandwidth, withsufficient accuracy for Ka band signal transmission, which has a relatively narrowbandwidth. Initially, the antenna is pointed at the selected satellite so as to receive theKu band signal. The system obtains a series of signal strength readings over a
predetermined azimuth (or elevation) region, such as plus/minus two degrees, from whicha new peak location is selected. Signal strength data is then obtained over a
predetermined elevation (or azimuth) region. Another signal peak location is selectedbased on the elevation data. Azimuth and elevation data are alternately collected forrefining the peak of the Ku signal so as to optimize Ka signal transmission capability.
