Enhancement of the centroiding algorithm for star tracker measure refinement

Acta Astronautica, 2003
Abstract The application of the hyperacuity technique to image processing of star trackers is analysed. An analytical study of the error introduced by the centroiding algorithm is presented and it is shown that a systematic contribution and a random one exist.

Universal star centroiding with stepping variant weighting integration

Guangxue Jingmi Gongcheng/Optics and Precision Engineering, 2011
In order to solve the centroiding problem of an over exposed star in star image processing,a universal centroiding algorithm was proposed with "first local calculation and then comprehensive integration".First,the existence of the over exposure stars was confirmed with real star images.Then,by analyzing the grey distribution of over exposed stars,the ...

An Autonomous Predictive Centroiding Algorithm for Star Sensor

Applied Mechanics and Materials, 2011
Of all current methods for measuring spacecraft attitude, the use of star sensors produces the most accurate measurements. Conventional star sensors repeat these processes with Lost-In-Space case. To advance the methods available to solve these problems, this paper presents an autonomous predictive centroiding algorithm for the star sensor.
