Abstract. Analytic expressions describing. The accuracy of determination of motion parameters of mass center of a space robot flying at a relatively short distance from a passive orbital object is considered. The investigation is based on the theory of analytical assessment of autonomous navigation system accuracy, and accounts for simultaneous measurements of angular and linear navigation parameters carried out with ground and onboard measuring means. The calculations performed on the example of primary navigation parameters measured by astronomical angle meter and a rangefinder are presented. The results demonstrate that the measuring means assure determination of all the parameters characterizing the movement of the space robot mass. The resulting covariance matrix of the errors of the robot navigation derived in analytic form, make it possible to form the complex of the robot measuring means at the stage of substantiation of its technical appearance.

Keywords: autonomous navigation, aerospace robot, object in orbit, analytical evaluation of precision navigation simultaneous measurements
