Abstract

SONG (Stellar Oscillations Network Group) is a Danish initiative to design and build a global network of 1-m class telescopes. The plan is to design and build a global network of small telescopes located at 8 existing observatories around the world. The scientific goals of SONG need to obtain long-term and continuous observations (weeks to months). The group behind the SONG proposal has devised a new and innovative concept to overcome these problems in a cost-effective way. China, 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 analysis of Chinese song telescope control system,ecpecially, its tracking system .
