ABSTRACT:
In a TVRO earth station having an antenna for receiving incoming satellite signals and polarizing means associated with the antenna for adjusting the relative alignment of the antenna orientation and the polarization of the incoming signals, an automatic polarization control system comprising means for producing an electrical control signal for controlling the polarizing means to adjust the relative alignment, means for detecting the noise level in the satellite signals received by the antenna, and means responsive to the detected noise level for adjusting the control signal, and thereby adjusting the polarizing means, to minimize the detected noise level.
