  1. 1. Ground Based Attitude Determination Using a SWIR Star Tracker

    University essay from Linköpings universitet/Reglerteknik

    Author : Karl Gudmundson; [2019]
    Keywords : Star Tracking; Celestial Navigation; Navigation Systems; Attitude; Orientation; SWIR; MEKF;

    Abstract : This work investigates the possibility of obtaining attitude estimates by capturing images of stars using a SWIR camera. Today, many autonomous systems rely on the measurements from a GPS to obtain accurate position and attitude estimates. READ MORE

  3. 2. Development of Star Tracker Attitude and Position Determination System for Spacecraft Maneuvering and Docking Facility

    University essay from Luleå tekniska universitet/Rymdteknik

  4. 3. 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
