Paper Abstract
Nano-JASMINE is a very small satellite mission for global space astrometry with milli-arcsecond accuracy, which
will be launched in 2011. In this mission, centroids of stars in CCD image frames are estimated with sub-pixel
accuracy. In order to realize such a high precision centroiding an algorithm utilizing a least square method is
employed. One of the advantages is that centroids can be calculated without explicit assumption of the point
spread functions of stars. CCD centroiding experiment has been performed to investigate whether this data
analysis is available, and centroids of artificial star images on a CCD are determined with a precision of less than
0.001 pixel. This result indicates parallaxes of stars within 300 pc from Sun can be observed in Nano-JASMINE.
