   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Maroš Hladký; [2018]
   Keywords : Visual Servoing; Vision Based Attitude Control; Feature detection; Feature Tracking;

   Abstract : The problematics of precise pointing and more specifically an attitude control is present sincethe first days of flight and Aerospace engineering. The precise attitude control is a matter ofnecessity for a great variety of applications. In the air, planes or unmanned aerial vehicles needto be able to orient precisely. READ MORE

3. 7. Robust and Agile Attitude Control for Triple CubeSat Eye-Sat

   University essay from KTH/Rymdteknik

   Author : Benjamin Charbaut; [2018]
   Keywords : ;

   Abstract : Eye-Sat is a student-designed 3U-CubeSat, to be launched to a sun-synchronous orbit from where it will map the zodiacal light, a faint glare caused by the reflection of Sun on interplanetary dust. Such mission requires an accurate 3-axis attitude control, for which Eye-Sat is equipped with reactions wheels, magnetorquers, magnetometers and a star tracker. READ MORE

4. 8. Adaptive filtering for maritime target tracking from an airborne radar

   University essay from KTH/Teknisk informationsvetenskap

   Author : Loïc Zimmer; [2018]
   Keywords : Bayesian estimation; nonlinearity; extended target tracking; joint tracking and classication; maritime targets; airborne radar; Bayesiansk berakning; icke-linjaritet; utstrackt malfoljning; simultan foljning och klassiering; maritima mal; luftburen radar;

   Abstract : Maritime target tracking from an airborne radar faces many issues due to the features of theenvironment, the targets to be tracked and the movement of the radar platform. Therefore, aunique tracking algorithm is not always able to reach the best possible performance for everyencountered situation. READ MORE

5. 9. Visualization of Quantified Self with movement and transport data

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : Emil Westin; [2017]
   Keywords : Visualization; Quantified Self; Sustainable HCI; Persuasive technology; Human Computer Interaction;

   Abstract : Transport systems account for a large part of the worlds CO2 emissions. In order to reach goals, set to lower emissions, we need to travel less by car and increase the use of sustainable means of transportation. READ MORE

6. 10. Development of Star Tracker Attitude and Position Determination System for Spacecraft Maneuvering and Docking Facility

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Serkan Dikmen; [2016]
   Keywords : star sensor; optical sensor; image processing; vision system; OpenCV; star tracker algorithms; voting methods; star catalog; attitude and position determination; star image; ground station; TCP communication; spacecraft maneuvering and docking facility;

   Abstract : Attitude and position determination systems in satellites are absolutely necessary to keep the desired trajectory. A very accurate, reliable and most used sensor for attitude determination is the star tracker, which orient itself in space by observing and comparing star constellations with known star patterns.
