Method and Apparatus for Determining Spacecraft Attitude by Tracking Stars
Procédé et appareil permettant de déterminer l'attitude d'un astronef par suivi d'étoiles
Abstract
A method and a device for determining the attitude of a spacecraft by attitude determination using fast star identification using a so-called star tracker is proposed with an improved algorithm with pattern extraction based on rings having an equal area. In some embodiments a confidence value is attributed to the candidates of the matching process improving significantly the verification process.
