The apparatus is for directing the position of the satellite antenna correctly by receiving the beacon signal generated from the satellite. The received signal is amplified in a low noise amplifier(3) through a duplexer(2). It is separated for data and beacon one in a distributor(4) and sends to a down converter(5) to form in low intermediate frequency. It is transmitted to a beacon receiver(7) through an IF filter(6). The transmitted signal is converted to low freq. DC and sent to a antenna controller(8) controlling a motor driver(9). Then motors(10,11) for elevation and direction angles are driven to the position at which the maximum input signal is received.
