COBAN (an abbreviation for "multi-spectral camera" in Turkish) is a Multi-spectral Earth observing camera system developed for BiLSAT, a 129 kg micro-satellite, which was launched into a 686 km sun-synchronous orbit in 27 September 2003. COBAN is one of the two Turkish R&D payloads hosted by BiLSAT in addition to the two primary imager payloads (a 4 band multi-spectral 26 m Ground Sampling Distance (GSD) imager and a 12 m GSD panchromatic imager). The technical specification of COBAN can be summarized as follows: Number of spectral bands: 8. Ground Sampling Distance: 12 meter. Image size (in pixels): 640 x 480 (KODAK KAI-0311 CCD) Wavelengths of the bands: 375-425 nm, 410-490 nm, 460-540 nm, 510-590 nm, 560-640 nm, 610-690 nm, 660-740 nm, 850-1000 nm Aimed primarily as a tool for improving the capabilities for instrument design for space, COBAN successfully performed in space. However, the most important outcome has been the lessons learned from mistakes during design, manufacturing and testing, that will hopefully help us avoiding serious failures in future missions.

ROTSE observations of the young cluster IC 348
Kiziloglu, U; Kiziloglu, N; Baykal, Altan (IOP Publishing, 2005-12-01)
CCD observations of stars in the young cluster IC 348 were obtained from 2004 August to 2005 January with the 0.45 m ROTSE-IIId robotic reflecting telescope at the Turkish National Observatory site, Bakirlitepe, Turkey. The timing analysis of selected stars whose X-ray counterparts were detected by the Chandra X-Ray Observatory were studied. The time series of stars were searched for rotational periodicity by using different period-search methods. Thirty-five stars were found to be periodic with periods ran...
On Orbit Modulation Transfer Function Estimation for BILSAT Imagers
Leloğlu, Uğur Murat (null; 2006-07-06)
BiLSAT, launched to its sun-synchronous orbit on 27.09.2003, is a 129 Kg small satellite carrying a panchromatic camera and a 4band multispectral camera with Ground Sampling Distances (GSD) 12.6 m and 28 m, respectively. The multispectral camera is composed of 4 totally independent cameras. All five refractive optic cameras have 2048 by 2048 frame CCDs as sensors. The overall Modulation Transfer Functions (MTF) of the imaging systems are very important for characterization of imagers. In this study, the MTF...
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...
DAG: A New Observatory And A Prospective Observing Site For Other Potential Telescopes
YEŞİLYAPRAK, Cahit; Yerli, Sinan Kaan; KESKİN, ONUR; Gucsav, B. Bulent (2016-07-01)
DAG (Eastern Anatolia Observatory is read as "Dogu Anadolu Gozlemevi" in Turkish) is the newest and largest observatory of Turkey, constructed at an altitude of 3170 m in Konakli/Erzurum province, with an optical and near-infrared telescope (4 m in diameter) and its robust observing site infrastructure. This national project consists of three main phases: DAG (Telescope, Enclosure, Buildings and Infrastructures), FPI (Focal Plane Instruments and Adaptive Optics) and MCP (Mirror Coating Plant). All these thr...
A search for supernova remnants in the nearby spiral galaxy M74 (NGC 628)
SONBAŞ, EDA; AKYÜZ, AYSUN; Balman, Şölen; Ozel, M. E. (EDP Sciences, 2010-07-01)
An optical search was carried out for supernova remnants (SNRs) in the Sc type nearby spiral galaxy M 74, using ground-based observations at the TUBITAK National Observatory (TUG, Antalya/Turkey) and the Special Astrophysics Observatory (SAO, Russia). Observations were supplemented by the spectral analysis of archived X-ray data from XMM-Newton and Chandra. The survey of M74 covered similar to 9 arcmin(2) with [S II], H alpha, and their continuum filters. Interference filter images of M 74 were obtained the...
