摘要：

Space solar power station works in a geosynchronous orbit to collect the solar energy and transmit it to the ground by laser or microwave energies. Due to the Earth's rotation and revolution, the angle between space solar power station and the sun changes all the time. In order to improve the output power of the space solar power station, it needs to track the direction of the sun. Therefore, this paper first analyzes the lighting changes in geosynchronous orbit in one year to achieve high-precision orientation of the sun. Then it designs the C8051F040 chip-based high-precision tracking controller according to the results of the analysis. The controller first acquires the basic position of the sun according to the time and location of the system, and then based on the output signals of the lighting sensors, the controller calculates the exact position of the sun and adjusts the position based on the results. The experimental result on the ground is good, and the tracking accuracy is better than 0.5%.
