The Control System of AST3

Shihai Yang, Fujia Du, Xiaoyan Li

Due to the extreme environment in Dome A, AST3 faces severe technical challenges, especially in the control system. The electrical elements such as sensors, motors should be used at low temperature. It is too cold for them to work properly during winter. And it's difficult for the telescope to track the target precisely with ultra-low speed in harsh environmental condition. The design and development of the control system of the second Antarctic Survey Telescope will be introduced.
