The invention provides a high-precision real-time tracking shipborne antenna attitude control system, mainly composed of an outer layer protective shell, a load bearing rotation module and a trackingadjustment module, wherein the load bearing rotation module comprises a stepping motor a, a stepping motor b, a rotating steel frame a, rotating steel frame b, a supporting steel frame 3, a rotating bearing and a rotating shaft; and the tracking adjustment module comprises a stepping motor a, a stepping motor b, an electronic compass, a microprocessor, a three-axis acceleration sensor and a three-axis gyroscope, the data collected by the electronic compass, the three-axis acceleration sensor and the three-axis gyroscope are transmitted to the microprocessor in one direction, and the microprocessor controls the rotation of the stepping motor a and the stepping motor b through processing so as to actively adjust the attitude. According to the high-precision real-time tracking shipborne antenna attitude control system provided by the invention, the deviation position is obtained more accurately by using the electronic compass, the three-axis acceleration sensor and the three-axis gyroscope; and the hysteresis quality of the attitude adjustment process is eliminated by using an active predictive tracking processing method, and high-precision direct communication between a ship and theground is achieved.
