Abstract
We investigate the periodic systematic error found in ground-based measurements of the BOKZ-M60 star sensor. This error can be explained by the periodic pixel structure of the sensor CCD matrix. Our conclusion is based on processing a sufficiently long series of measurement data. The measurements are processed in a few stages. First, we approximate the stellar sky motion on the matrix plane using an appropriate mathematical model. Then, we trace the motion of some particular stars relative to the model sky motion. Using spectral analysis, we then find the periodic components of their motion. The period of those components allow us to make the conclusion given above.
