Abstract

PURPOSE:To reduce the working cost of each subordinate station by reducing the power consumption of each subordinate station by constituting at a main station side a controller which determines the antenna driving directions of subordinate stations. CONSTITUTION:At subordinate station Q, a pilot signal from communication satellite 11 is received by antenna 6 and received and detected by pilot receiver 8 via low-noise amplifier 7 and its detection output is substituted by a level of a reference frequency having the base band through reference-frequency-wave transmitting means 12, thereby sending it from antenna 6 to communication satellite 11. At a master station, the signal from subordinate station Q is demodulated by demodulator 17 to detect a reference frequency signal and driving-direction assignment frequency transmitting means 18 transmits a signal of the frequency that for example, corresponds to the left direction of axis AZ, to radiate it from antenna 1 to communication satellite 11 via modulator 19 and frequency converting amplifier 20. On receiving this signal, subordinate station Q drives antenna 6 to the left direction of axis AZ on the basis of this signal.
