The tracking system of the TAIGA-IACT telescope — •Dmitriy Zhurov^1,2, Oleg Gress¹, and Ralf Wischnewski³ for the TAIGA collaboration — ¹Irkutsk State University — ²Irkutsk National Research Technical University — ³DESY Zeuthen

The TAIGA Observatory is designed for ground based gamma-ray astronomy in the energy range from a few TeV to several PeV, and is located in the Tunka valley (Siberia/Russia). The TAIGA-IACT telescopes are part of the TAIGA complex hybrid detector that is under deployment. Currently we have one IACT telescope in operation and two more telescopes under construction on the TAIGA site. Observation of a gamma-source with IACT telescopes requires long exposure time, accurate pointing and specific tracking modes that are used for this type of telescope. The telescope drive system is equipped with 17-bit shaft encoders and hybrid stepper motors. A CCD-camera located on the telescope dish is intended for telescope calibration and measurements of its absolute direction by the images. Telescope hardware are controlled with software developed using EPICS control system framework. In this report we overview TAIGA-IACT telescope pointing calibration and tracking control software. Also telescope pointing precision for the 2018-2019 observation season is presented.
