The paper presents a video data processing system application for angular measurement of the space object orbits in operating mode at the ground-based optical observation station of the Belarusian State University. The development of a sustainable detection system, localization, and identification of space objects is based on the research of the video stream difference frames in the spatial and frequency domains. The method for finding the small moving object of unknown brightness against the quasi-periodic noise background is discussed. Particularly the Fourier transform of a difference frame from a projection's weighted sum to detect and study the motion properties of faint objects is used. The multithreading in the proposed architecture of the video data processing system is realized. The read and write rate of raw video data from an active camera is up to 40 fps. Time synchronization is carried out by reference clock of remote servers and GNSS unit with an accuracy of 1 ms. The result of the experimental survey of the space object orbits angular measurement by the video data processing system in the operating mode of the ground-based optical observation station is performed. The proposed system allows obtaining the space object orbit angular measurement with an accuracy of 0.1 degree.
