(TAI), a new Attitude Determination Control Unit (ADCU) has been developed. The present study involves the Thermal Vacuum Cycling Tests (TVCT) performed on the ADCU and the thermal mathematical model developed in order to assess the thermal behavior of the equipment under vacuum environment. For the qualification of the ADCU, 8 cycles of TVCT has been performed in a Thermal Vacuum Chamber (TVC). By demonstrating that the functional performance of the ADCU lies within required limits, it was shown that the ADCU is a space-qualified equipment. In addition to this, a thermal mathematical model representing the ADCU and the thermal test environment are developed using THERMICA software and simulations based on this model are carried out by SINDA/G software. Transient and steady-state predictions obtained with the software are compared with the test measurements and a good agreement was observed. Based on this agreement, it is concluded that the mathematical model employed in the present study produces accurate results for the thermal behavior of the ADCU and it is an efficient tool which can be used in the design phases of future equipment with similar properties.","PeriodicalId":285002,"journal":{"name":"Proceedings of 5th International Conference on Recent Advances in Space Technologies - RAST2011","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123164286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it is possible to manually locate buildings from very high resolution images; this operation may not be robust and fast. Therefore, automated systems to detect buildings from very high resolution aerial and satellite images are needed. Unfortunately, the solution is not straightforward due to the diverse characteristics and uncontrolled imaging conditions of the scenes. To overcome these difficulties, herein we propose a novel solution to detect buildings from very high resolution grayscale aerial and panchromatic Ikonos satellite images using structural features and probability theory. For this purpose, we extract structural features from the given test image using a steerable filter set. Extracted structural features indicate geometrical properties of objects in the image. Using them, we estimate the probability density function (pdf) which indicates locations of buildings to be detected. Our extensive tests on a large and diverse data set indicate the robustness and practical usefulness of our method.","PeriodicalId":285002,"journal":{"name":"Proceedings of 5th International Conference on Recent Advances in Space Technologies - RAST2011","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127012638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
