SONG (Stellar Oscillations Network Group) is a Danish initiative to design and build a global network of 1-m class telescopes, which plans to design and build a global network of small telescopes located at 8 existing observatories around the world. China SONG, as one of the eight sites, its 1-m class telescope can achieve the goal for long time continuous, uninterrupted, full automatic observation and works in the diffraction limit condition. At the same time the telescope must realize 0.3 arc second tracking precision without guide star, which is a very challenge and difficult task for 1 meter telescope tracking system .This paper discusses the design and control of the tracking system of Chinese SONG telescope in detail.
