Abstract: We investigate the periodic systematic error found out in ground-based measurements of the star sensor BOKZ-M60. This error can be explained by periodic pixel structure of the sensor CCD matrix. Our conclusion is based on processing sufficiently long series of measurement data. The measurements were processed in a few stages. First, we approximate the motion of star images in the matrix plane and trace the development of some individual stars. Using spectral analysis, we found periodic components of their motion. The period of those components allow us to make the above conclusion.
