520.25Abstract
In January 2012 the Observatory of Kuban State University was invited to participate in the international project Radioastron, with the aim of achieving a coordinate-time information about the spacecraft "SPEKTR-R" for transmission later to the ballistic center of Keldysh Institute of Applied Mathematics. Angular astrometric measurements are an important addition to the navigation data of the spacecraft "SPEKTR-R", allowing to improve the accuracy of spatial-temporal reference of data of the scientific experiments carried out by the space Observatory. Measurements obtained in the optical astrophysical observatory of the Kuban State University demonstrate high accuracy, the noise components of the errors are less than 0.5 arc-seconds. During 5 years the astrophysical Observatory of the Kuban state University conducted 369 sessions of observation of the spacecraft "SPEKTR-R", in which it was received 10285 measurements of the angular position of the spacecraft on the celestial sphere. The total time of observation amounted more than 440 hours, which is an absolute record among all the optical observations of the spacecraft "SPEKTR-R" in the world.
