| Abstract: | Errors in pointing and sustaining Spektr-R are estimated based on the data of star sensors and an angular velocity vector meter, and the calculated values are compared with the observed values. It has been indicated that the achieved pointing accuracy is significantly better than the required accuracy and is independent of the number of star sensors used for this purpose; finally, the stabilization parameters correspond to the anticipated parameters. The original method for processing adjustment observations of the space radio telescope in the 1.35-cm range used to find a systematic deviation of 2.5′ of the telescope real electric axis from the nominal angular position has been described. |
