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

   Master-uppsats, Linköpings universitet/Reglerteknik

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

   Sammanfattning : 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. LÄS MER

3. 2. High Resolution Filter for Stable Spacecraft Attitude Estimation

   Master-uppsats, KTH/Optimeringslära och systemteori

   Författare :Kristin Rynninger Eriksson; [2014]
   Nyckelord :;

   Sammanfattning : In this thesis a filter for attitude estimation using sensor fusion of a Star Tracker and a Gyroscope are designed and implemented for integration on the European Data Relay satellite, EDRS. The performance of three filters, Multiplicative Extended Kalman Filter, Unscented Kalman Filter and Particle filter, are evaluated in terms of attitude error, covariance convergence and change of attitude knowledge uncertainty.
