Progress cargo spacecraft observed with the AZT-33IK optical telescope

Abstract

In this paper, we describe a telescope and measuring equipment used for optical observations of Progress cargo spacecraft (PCS), which were made during Radar–Progress space experiment sessions. We also demonstrate object tracking and measurement techniques. The observations were made with the optical telescope AZT-33IK at the Sayan Solar Observatory of ISTP SB RAS. During many of the sessions, we registered optical phenomena that occurred in regions of space surrounding the PCS and appeared due to the work of PCS onboard engines. The data we obtained can be used to independently control the geometry of the experiment and to analyze physical conditions in outer space.
