Design and implementation of satellite tracking control system based on software bus

Satellite tracking control is an important technology in satellite communication. A satellite tracking control system based on soft bus mechanism is designed and the key design scheme is given. Hardware platform aspect processing chip adopts FPGA+ARM ZYNQ processing platform to ensure the requirements of processing resources and interface expansion in the system. In terms of software, the data management mechanism and communication agent mechanism of the soft bus are constructed to solve the problems of high coupling degree and difficult precise control of trigger conditions in the traditional system, so that the software architecture of the tracking system is clear and the interface of each functional module is efficient, convenient and extensible. In the design of tracking process, the timing of tracking Angle adjustment is optimized, so that the tracking algorithm and peripheral control can be processed in parallel, and the processing resources are fully utilized. Finally, a testing environment is built to verify the system capability. The results show that the design is effective and reliable, and the soft bus mechanism can also be applied to other complex environment of external devices, which has high application and promotion value.
