Abstract: Based on the research of the biaxial tracking system, the driving mechanism of the biaxial tracking system wasdesigned, and the dynamic characteristics of the driving mechanism of the altitude-angleand azimuth-angle wereanalyzed. The metering module composed of four photoelectric sensors weredesigned, which was the orthogonalmetering module. The control system wascomposed of the single chip microcomputer.The results showed that the orthogonalmetering module and the motors to realize the real-time tracking of the sunlight.

Key words: solar tracking, orthogonalmetering, double-axle transmission, dynamic analysis
