发明名称 Process for resighting telecommunication antennas and apparatus for carrying it out
摘要 A process for realigning telecommunication antennas with satellites wherein the radio-electric axis of reception of the antenna which receives a signal from the satellite is periodically modulated after which the received signal is multiplied by a sinusoidal signal of the same frequency and same phase as the periodic moudulation applied to the radio electric axis during reception of the signal and wherein thre multiplied signal is filtered to remove all frequencies equal to or higher than the frequency of the periodic modulation and thereafter the filtered signal as amplified in order to deduce the direction in which the antenna should be realigned and subsequently realigning the antenna by activation of the motor control mechanisms associated with the antenna.
