Abstract

AMOS SA has been awarded of the contract for the design, manufacturing, assembly, tests and on site installation (Nainital, Devasthal site at 2540 mm altitude) of the 3,6 m Optical Telescope for ARIES (Aryabhatta Research Institute of Observational Sciences), Nainital (India). This paper describes the architecture deployed for the whole telescope control. It contains, in others, the Telescope Control System (TCS), the Active Optic System (AOS) and the Auto Guiding Unit (AGU). The TCS generates the telescope axes trajectory from the celestial coordinates selected by the operator and drives the main axes. The AOS generates the force set points for each M1 actuator and the position set point of the M2 hexapod from the data given by a wave front sensor. The AGU sends the main axes corrections from the movement of the guide star on the guiding CCD. The modules shall communicate between them to optimize the telescope behavior and with the Observatory Control System (OCS) for data reporting and synchronization with the instrument.
