Description

The Small-Sized single-mirror Telescopes (SST-1Ms) are designed to observe the gamma rays within the TeV range. The two 4-meter diameter Davies-Cotton SST-1M telescopes are operated at the Ondřejov Observatory of the Astronomical Institute of the Czech Academy of Sciences near Prague. The telescopes use White Rabbit for time synchronization, enabling the detection of coincident events in stereo mode to the performance. The telescopes are remotely operated via a graphical user interface, which allows users to define the source list, execute calibration procedures and monitor telescope subsystems during operation. Onsite data analysis is conducted after the observation provides daily analysis results. The observatory is equipped with an atmospheric monitoring system, including All Sky Camera, an infrared lidar (Ceilometer) and an environmental monitoring system, ensuring accurate measurement of observation conditions. Additionally, the optical point spread function and the pointing accuracy of the telescope are regularly checked to maintain proper operation and reliable data analysis. We present an overview of the telescope hardware, the operation framework and the calibration scheme of the stereoscopic system.
