Abstract

In this paper, a novel solution is introduced for accurate subpixel star centroiding of the focused geostationary Earth observing sensor on a three-axis stabilized satellite. A small 2-dimensional array is utilized to better capture the star spot than the linear array of detectors. The popular center of mass method is used to compute star centroid in a single frame. Then the subpixel accuracy of star centroiding can be improved by fitting the linear trajectory of the observed star according to exact imaging time produced from time awarding system of the satellite. Experimental results on simulated star images in various conditions validate the effectiveness and robustness of our star centroiding method.
