This paper parabolic satellite antenna aims to track the precise location of a moving ship or, in the car that can be used to design the system. That was previously used with the reaction rate of a stepping motor, BLDC motor, in order to suppress the noise two-axis control and a separate encoder to the six degrees of freedom motion system was implemented in a precise location. In order to overcome various disturbances gyro sensor Yaw, Pitch, Roll 3 axes were used. To respond immediately to the disturbance at the same time, two-axis motor by controlling the precise location of the system was designed to compensate instantaneously. In addition, the circle tracking algorithm has applied for our system. We designed that the AGC signal of digital tuner quickly had gone to up to the maximum point. In order to solve the various communication errors such as moving the antenna or ground, we had designed the control system
