With the gradual increase of aviation users" demand for Internet access, combining with aerospace manufacturing, satellite communication and inertial stabilization platform technology, a Ku/Ka dual-frequency airborne dynamic communication system based on APT control technology is designed. The system has high dynamic response and accurate satellite acquisition and tracking capability. APT control technology integrates the key technologies of gyroscopic stability, drift compensation, multi-data fusion and precise servo control. The system adopts program tracking and dynamic tracking control strategy, Ku and Ka antenna switching and satellite alignment can be quickly completed under different carrier disturbance according to ModMan control instructions, so as to ensure normal link communication and provide multi-level communication service guarantee for aviation users with the best bandwidth service concept. At present, the prototype development, simulation of ground sports car and test of swing table have been completed. The technical performance is conformed with the overall design requirements,and it has a good application prospect.
