Description
Summary:	The paper considers problems of creation and control associated with the manufacturing process of BOKZ family star trackers intended for determining attitude (orientation) of space vehicles of various purpose. The hardware and software complex (HSC) was designed for BOKZ control. In addition to determining the elements of internal orientation, this complex, allows to determining the methodical error - the discrepancy found in the calculated center-weighted center of the point source image. Analysis of the methodical error manifestation is presented, the connection of its appearance with the ratio of the image sensor pixel size and star image is shown. A number of experiments were carried out with the HSC, the errors introduced by the complex were identified and the methods for their minimization were proposed.
