Satellites in orbit today make use of at least one star tracker and they are also employed in Earth and space bound telescopes\, ballistic missiles\, tanks and night navigating ships. In th is talk\, I’ll be presenting the first national star tracker system deve loped by the Tubitak Space Research Center and myself for the target Turks at 6A and IMECE satellite platforms. The star tracker device has two main operating modes: Lost-In-Space Mode\, where the device cold-starts at an u nknown orientation and tries to orient itself in some number of seconds an d the Tracking Mode\, where the star tracker updates its orientation from a known initial orientation in real-time (>10Hz) using the incoming video stream. Additionally\, star tracker also needs to be able to operate in ha rsh environmental factors of space like high temperature gradients\, inten se vibrations during orbital launch and constant radiation. These environm ental factors result in shifts and decays in the calibration of the hardwa re which need to be compensated for in software. I’ll be presenting the design and development of the algorithms used in the star tracker in order to ensure the required speed and accuracy targets throughout its operatio n lifetime.\n\nBio: Engin Tola received his BS and MS degrees in Electrica l and Electronics Engineering from the Middle East Technical University in 2003 and 2005 respectively with Signal Processing as a sub-specialty. Aft er that he completed his PhD studies in Computer Vision from École Polyte chnique Fédérale de Lausanne\, Switzerland in 2010. He then founded Aurv is R&D – a computer vision and machine learning research and development company in Ankara. He is primarily interested in 3d geometrical scene und erstanding\, reconstruction\, localization and exploration problems in rea l-time and offline camera systems for land-based or flying robotic platfor ms. During his 10 years in the industry\, he developed algorithms and prod ucts for companies like Autodesk\, Dronedeploy and Tubitak Space Research Center. He is also a co-founder of Argutek – a mobile augmented reality focused company and Docu.ai – a San Francisco based AI-powered data extr action company.\n\nSpeaker(s): Dr. Engin Tola\, \n\nAnkara\, Ankara\, Tür kiye LOCATION:Ankara\, Ankara\, Türkiye ORGANIZER:ozergul@metu.edu.tr SEQUENCE:0 SUMMARY:IEEE AP/MTT/EMC/ED TURKEY CHAPTER SEMINAR SERIES -- SEMINAR 63 URL;VALUE=URI:https://events.vtools.ieee.org/m/215247 X-ALT-DESC:Description: <br /><p><strong>20 December 2019 (12:40): &nbsp\;I EEE AP/MTT/EMC/ED Turkey Seminar Series (S.63)</strong></p>\n<p>Speaker: D r.
