Structure of mobile active antenna system and satellite tracking method using the same

PURPOSE: A structure of a mobile active antenna system and a satellite tracking method using the same are provided to enhance tracking accuracy, reduce tracking loss, and accurately track. CONSTITUTION: A structure of a mobile active antenna system comprises an antenna radome part(51) and an active antenna signal processing part(52). The antenna radome part(51) includes four groups of m active channel parents(511,512,513,514), four signal power combiners(515,516,517,518), a beam forming block(519), a rotating power(520), a tracking signal converter(521), a beam orientation controller(522), a rotation platform(530), a rotary jointer(523), a frequency converter(524) and a driving controller(528). The active antenna signal processing part(52) includes a satellite tracking processor(527), an electronic direction sensor(526), and a power module(525). The active channel parents includes radiating array, first low noise amplifiers, a signal power combiner, a second low noise amplifier, a phase shifter, a phase shifter drive, and a signal power attenuator. The beam forming block(519) includes four low noise amplifiers, four phase shifter, four phase shifter drive, and tow signal power combiner.
