PURPOSE: A vehicle satellite broadcasting antenna system is provided to always receive a satellite electric wave through a receiver by tracking a satellite even though a posture of a vehicle changes. CONSTITUTION: A receiver(17) receives a satellite electric wave. A drum(19) rotates the receiver(17). A motor(21) provides a rotating power to the drum(19). A motor controller(23) controls the motor(21) according to a signal from the receiver(17). A sensor senses a slop angle of a vehicle according to a posture of the vehicle. An operator operates a posture of the receiver(17) up and down even though a posture of a vehicle changes. An operator controller(25) controls the operator according to an input signal of the sensor. The sensor is connected to an input side of the operator controller(25) and the operator is connected to an output side of the operator controller(25).
