The satellite technology has been attracting the attention of governments and companies with increasing areas of application. For any of these application areas, reliable and rugged design of satellite is essential. In case there is a failure on satellite, according to its severity, it may lead to the loss of the mission or even the satellite. Therefore, assessing possible satellite failures that might occur during its operational life and taking precautions in the design phase is very critical for satellite programs. In general, numerical reliability analysis starts with setting numerical reliability objective at satellite level, and then allocating the numerical value within lower levels. After all, analysis is verified with performing bottom-up reliability prediction analysis. However, typical reliability prediction analysis uses failure rate data from well-known reliability libraries, statistical evaluations, probability distribution models and all of them include various uncertainties. Because of these uncertainties, reliability prediction result may be too conservative or the opposite way round too loose which can result with overdesign or under-design satellite respectively. In this study, in order to reduce these design handicaps, usage of real life data for reliability prediction analysis will be evaluated. A method to compare the reliability prediction analysis of a satellite sub-system with the results of failure estimation algorithm using the real satellite failures observed in space will be proposed.

Satellite attitude control by integrator back-stepping with internal stabilization Doruk, Resat Oezguer; Kocaoglan, Erol (2008-01-01) Purpose - This paper aims to focus on the implementation of the integral back-stepping control on the model of BILSAT - 1 satellite of the Turkish Scientific and Technological Research Council (TUBITAK).
Determination of sea level trends and vertical land motions from satellite altimetry and tide gauge observations at the Mediterranean Coast of Turkey Karabil, Sıtar; Karslıoğlu, Mahmut Onur; Demir, Coşkun; Department of Geodetic and Geographical Information Technologies (2011) A radar altimetry satellite measures the height of sea surface globally. However, tide gauges, measuring Sea Level Height (SLH), are set up on the Earth surface. Hence, SLHs are involved in vertical motion of the Earth crust. In this study, vertical motions of Earth crust have been separated from sea level variations. After clustering of SSH observations with K-means approach, two outlier detection methods Pope and Interquartile (IQR) Tests are implemented in data. Afterwards, each altimetry measurement is ...
Conceptual design optimization of a nano-satellite launcher Arslantaş, Yunus Emre; Tekinalp, Ozan; Department of Aerospace Engineering (2012) Recent developments in technology are changing the trend both in satellite design and application of that technology. As the number of small satellites built by experts from academia and private companies increases, more effective ways of inserting those satellites into orbit is needed. Among the various studies that focus on the launch of such small satellites, research on design of Launch Vehicle tailored for nano-satellites attracts special attention. In this thesis, Multiple Cooling Multi Objective Simu...
Airport runway detection in satellite images by Adaboost Learning ZÖNGÜR, Ugur; Halıcı, Uğur; AYTEKİN, Orsan; Ulusoy, İlkay (2009-09-03) Advances in hardware and pattern recognition techniques, along with the widespread utilization of remote sensing satellites, have urged the development of automatic target detection systems in satellite images. Automatic detection of airports is particularly essential, due to the strategic importance of these targets. In this paper, a runway detection method using a segmentation process based on textural properties is proposed for the detection of airport runways, which is the most distinguishing element of...
Feasibility study on thermal survivability of X-Band subsystem on RASAT microsatellite Okan, A (2005-06-11) After the launch and commissioning of the first Turkish remote sensing satellite BILSAT-1(center dot), TUBITAK BILTEN has initiated the RASAT microsatellite project. RASAT will be a remote sensing microsatellite at low Earth orbit (LEO), with a mass of around 100 kg and an orbital average power of 38W. RASAT is planned to he launched in 2007 and will be the first satellite to be designed and manufactured entirely in Turkey.
