The Turkish DAG 4-m telescope is currently through the final design stage. It is to be located on a 3170 m mountain top in Eastern Anatolia. The telescope will be a state-of-the art device, alt-az mount with active primary and adjustable secondary and tertiary mirrors. Its optics design is specially aimed at being compatible with advance adaptive optics instrumentation. The ultimate performance of such a telescope results of multiple concurrent effects from many different components and active functions of the complex system. The paper presents a comprehensive integrated (end-to-end) model of the telescope, comprising in one computational sequence all structural, electrodynamics and oactive optics performance that produce the image quality at the focal plane. The model is entirely programmed in Matlab/Simulink and comprises a finite element model of structure and mirrors, dynamics modal reduction, deformation analyses of structural and optical elements, active optics feedback control in the Zernike modal space.

Agile development approach for the observatory control software of the DAG 4m telescope Gucsavd, B. Bulent; Coker, Deniz; YEŞİLYAPRAK, Cahit; KESKİN, ONUR; Zago, Lorenzo; Yerli, Sinan Kaan (2016-06-30) Observatory Control Software for the upcoming 4m infrared telescope of DAG (Eastern Anatolian Observatory in Turkish) is in the beginning of its lifecycle. After the process of elicitation-validation of the initial requirements, we have been focused on preparation of a rapid conceptual design not only to see the big picture of the system but also to clarify the further development methodology. The existing preliminary designs for both software (including TCS and active optics control system) and hardware sh...
Preliminary results of the alignment and Hartmann tests of the AZT-22 telescope Aslan, Z; Bikmaev, IF; Vitrichenko, EA; Gumerov, RI; Dembo, LA; Kamus, SF; Keskin, V; Kiziloglu, U; Pavlinsky, MN; Panteleev, LN; Sakhibullin, NA; Selam, SO; Sunyaev, RA; Khamitov, I; Yaskovich, AL (2001-06-01) The AZT-22 telescope installed in Turkey (Antalia) was aligned and tested on stars by the Hartmann method. The rms normal deviation of an equivalent optical system is 0.040 +/- 0.016 mum. The circle of confusion is 0.40 +/- 0.04 arcsec in diameter at a 50% energy level.

A Comparative Study on Structural Wall Design Approach of 2007 Turkish Seismic Code Kurç, Özgür; Lulec, Andac; Ozcebe, Guney (2011-07-01) The new version of the Turkish Seismic Code was released in 2007 and the capacity design approach for high ductility structural walls was introduced for the first time. The practicing engineers, however, mentioned various problems especially related with the shear design of structural walls. Because of this reason, an in-depth comparative study was conducted to examine the differences and similarities of the design approaches of Turkish Seismic Code, American Reinforced Concrete Code and various studies in ...
Geometric Camera Calibration of BiLSAT Small Satellite Preliminary Results Friedrich, Jurgen; Leloğlu, Uğur Murat; Tunalı, Erol (null; 2006-02-14) The interior geometric calibration of the multi-spectral camera of BiLSAT satellite is aimed using three sets of images from Ankara. Each set contains four different images for channels Red, Green, Blue (RGB), and Near Infra Red (NIR) in which well-defined target points were identified and their image coordinates measured. The target points’ UTM coordinates were extracted from aerial photos or topographic maps and collected from field using hand-held GPS receiver. A least square parameter estimation was the...
Auxiliary free space optical communication project to ensure continuous transfer of data for DAG the 4m telescope KESKİN, ONUR; YEŞİLYAPRAK, Cahit; Yerli, Sinan Kaan (2016-07-01) The continuity of the amount of data that the 4m DAG (Eastern Anatolia Observatory in Turkish) telescope will produce and transfer to Ataturk University is critical not to jeopardize the science programs. Though t he fiber optics and radio link infrastructures are in place, these systems are still volatile against earthquakes, and possible excavation damages. Thus the 4m DAG telescope will be equipped with a free space optical communication system to ensure the continuity of the data transfer as a backup sy...
