Satellite signal automatic tracker

The utility model discloses a satellite signal automatic tracker which is composed of a master control unit module, a central frequency spectrum analysis module, a satellite signal acquisition module, a power supply module and a motor drive module. The satellite signal acquisition module is connected with the central frequency spectrum analysis module and the power supply module. The central frequency spectrum analysis module is connected with the master control module and the power supply module. An acquired target satellite signal is analyzed and processed and then converted into a corresponding DC voltage signal to be transmitted to the master control unit module to be processed. The master control unit module is connected with a rotating stand module and the power supply module. According to the satellite signal automatic tracker, the satellite signal can be acquired according to a high-frequency head installed on an antenna plane, then the acquired signal is analyzed by the frequency spectrum analyzer and then transmitted to the master control unit module, and then movement, pitching and rolling rotation of two DC motors are driven so as to adjust the posture of the antenna plane, and the high-frequency head is enabled to constantly receive the satellite signal. The satellite signal automatic tracker is widely applicable to navigation.
