  5. 4. Determining the Requirements for the Star Tracker on JEM-EUSO

    University essay from KTH/Fysik

    Author : Youssef Dhraief; Farid Hedayati; [2015]
    Keywords : ;

    Abstract : This work will focus on how the JEM-EUSO project, which orbits around Earth on the International Space Station and whose purpose is to detect air shower from the atmosphere caused by high energy particles from outer space, will be able to determine its positon once it detects such air shower. This is best done by adding a star tracker to it. READ MORE

  6. 5. A Method for Detecting Resident Space Objects and Orbit Determination Based on Star Trackers and Image Analysis

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion; Uppsala universitet/Bildanalys och människa-datorinteraktion

    Author : Karl Bengtsson Bernander; [2014]
    Keywords : Image analysis; Space situational awareness; Orbit determination;

    Abstract : Satellites commonly use onboard digital cameras, called star trackers. A star tracker determines the satellite's attitude, i.e. its orientation in space, by comparing star positions with databases of star patterns. READ MORE
