PURPOSE:To perform synchronizing control of low cost and high transmission efficiency, by using the angle of elevation information obtained from the angle detector of the antenna with comparatively simple addition of hard/software, calculating the delay in propagation and correcting the transmission timing. CONSTITUTION:The synchronizing control unit 14 obtains the delay in the propagation of the station with the angle of elevation information obtained from the angle detector 15 provided with each station for automatic tracking of the antenna 4, and the frame length and the waiting time until the station slot are added when the reference timing is received from the base station to determine the transmission timing. Based on the transmission timing signal, the synchronizing control unit 14 controls the start time when the data exchanger 10 sends the data to the transmission buffer 7 and controls the transmission gate 6 so that electromagnetic waves are sent by the transmission time of the data burst of the station. |
