Dogu Anatolu Gozlemevi (DAG-Eastern Anatolia Observatory) Project is a 4m class optical, near-infrared Telescope and suitable enclosure which will be located at an altitude of similar to 3.170m in Erzurum, Turkey. The DAG telescope is a project fully funded by Turkish Ministry of Development and the Ataturk University of Astrophysics Research Telescope - ATASAM. The Project is being developed by the Belgian company AMOS (project leader), which is also the optics supplier and EIE GROUP, the Telescope Main Structure supplier and responsible for the final site integration. The design of the Telescope Main Structure fits in the EIE TBO Program which aims at developing a Dome/Telescope systemic optimization process for both performances and competitive costs based on previous project commitments like NTT, VLT, VST and ASTRI. The optical Configuration of the DAG Telescope is a Ritchey-Chretien with two Nasmyth foci and a 4m primary thin mirror controlled in shape and position by an Active Optic System. The main characteristics of the Telescope Main Structure are an Altitude-Azimuth light and rigid structure system with Direct Drive Systems for both axis, AZ Hydrostatic Bearing System and Altitude standard bearing system; both axes are equipped with Tape Encoder System. An innovative Control System characterizes the telescope performance.

Project Management of DAG: Eastern Anatolia Observatory KESKİN, ONUR; YEŞİLYAPRAK, Cahit; Yerli, Sinan Kaan; Zago, Lorenzo; Guver, Tolga; Alis, Sinan (2016-06-28) The four meter DAG (Eastern Anatolia Observatory in Turkish) telescope is not only the largest telescope in Turkey but also the most promising telescope in the northern hemisphere with a large potential to offer scientific observations with its cutting edge technology. DAG is designed to be an AO telescope which will allow both infrared and visible observations with its two Nasmyth platforms dedicated to next generation focal plane instruments. In this paper, status updates from DAG telescope will be presen...
DAG Telescope: A New Potential for MOS Observations ALİŞ, Sinan; YEŞİLYAPRAK, Cahit; Yerli, Sinan Kaan (2015-03-06) East Anatolian Observatory (aka. DAG) is a national project supported by the Turkish Government for building a 4m class telescope which will be working in the optical and near-IR domain. As the tender process has been completed and kick-off to the telescope and the mirror production has been initiated, the project team is looking for possible collaborations for the focal plane instrumentation. This contribution is intended to describe the DAG project and to show its opportunities for a state-of-the-art MOS ...
A Microwave Kinetic Inductance Detector for the DAG Telescope GÜVER, Tolga; Mazin, Benjamin A.; O'Brien, Kieran; Kay, Burak; Alis, Sinan; Yelkenci, F. Korhan; YEŞİLYAPRAK, Cahit; Yerli, Sinan Kaan; Erol, Ayse; KESKİN, ONUR (2016-06-29) We present the details of a proposed microwave kinetic inductance detector (MKID) for the DAG (Eastern Anatolia Observatory in Turkish) telescope, DAG-MKID. The observatory will have a modern 4m size telescope that is currently under construction. Current plan to obtain the first light with the telescope is late 2019. The proposed MKID based instrument will enable astronomers to simultaneously detect photons in the relatively wide wavelength range of 4000 - 13500 ˚A with a timing accuracy of µs and spectral...
Different orbit determination algorithms for BİLSAT-1 Ural, Serkan; Karslıoğlu, Mahmut Onur; Department of Geodetic and Geographical Information Technologies (2006) This study aims to investigate different orbit determination algorithms for the first Turkish remote sensing satellite, BILSAT-1. The micro-satellite carries an onboard GPS receiver. Pseudorange measurements simulated from the position and velocity data supplied by TÜBITAK-BILTEN are used for the implementation of different orbit determination algorithms concluding to an estimate of the satellite̕s state. Satellite̕s position, velocity components and the GPS receiver̕s clock bias are selected as the state p...
EASTERN ANATOLIA OBSERVATORY (DAG): RECENT DEVELOPMENTS AND A PROSPECTIVE OBSERVING SITE FOR ROBOTIC TELESCOPES YEŞİLYAPRAK, Cahit; Yerli, Sinan Kaan; KESKİN, ONUR (2015-10-02) This document (Eastern Anatolia Observatory (DAG) is the new observatory of Turkey with the optical and near-infrared largest telescope (4 m class) and its robust observing site infrastructure. This national project consists of three phases with DAG (Telescope, Enclosure, Buildings and Infrastructures), FPI (Focal Plane Instruments and Adaptive Optics) and MCP (Mirror Coating Plant) and is supported by the Ministry of Development of Turkey. The tenders of telescope and enclosure have been made and almost al...
