ABSTRACT:
A control system for adjusting an antenna rotatably mounted on a vehicle to directly receive a transmitting signal from a geostationary satellite so as to apply it to a receiving equipment on the vehicle. The control system comprises a first sensor for sensing a first difference between a standard direction and a travelling direction of the vehicle, a second sensor for sensing a second difference between the travelling direction of the vehicle and a direction of the antenna, a microcomputer programmed to determine a third difference between the travelling direction of the vehicle and a direction of the satellite in accordance with the first difference on a basis of a predetermined difference between the standard direction and the direction of the satellite and to determine an adjustment angle for rotation of the antenna in accordance with the second and third differences, and an actuator for effecting for rotation of the antenna with the adjustment angle.
