TCS and peripheral robotization and upgrade on the ESO 1-meter telescope at La Silla Observatory

In this work we describe the robotization and upgrade of the ESO 1m telescopelocated at La Silla Observatory. The ESO 1m telescopewas the first telescopeinstalled in La Silla, in 1966. It now hosts as a main instrument the FIber Dual EchellE Optical Spectrograph(FIDEOS), a high resolution spectrographdesigned for precise Radial Velocity (RV) measurements on bright stars. In order to meet this project's requirements, the TelescopeControl System (TCS) and some of its mechanical peripherals needed to be upgraded. The TCS was also upgraded into a modern and robust software running on a group of single board computersinteracting together as a network with the CoolObs TCS developed by ObsTech. One of the particularities of the CoolObs TCS is that it allows to fuse the input signals of 2 encoders per axis in order to achieve high precision and resolution of the tracking with moderate cost encoders. One encoder is installed on axis at the telescopeand the other on axis at the motor. The TCS was also integrated with the FIDEOS instrument system so that all the system can be controlled through the same remote user interface. Our modern TCS unit allows the user to run observations remotely through a secured internet web interface, minimizing the need of an on-site observer and opening a new agein robotic astronomy for the ESO 1m telescope.
