Optical electronic system for detection and measurement of space debris movement parameters (OEK OKM)

OEK OKM is intended for independent search and detection of space objects in low, geostationary, circular semidiurnal and highly elliptical orbits, determination of angular coordinates and photometry of the detected spacecraft, identification of the detected spacecraft against the space objects listed in the system’s database, as well as output of the obtained coordinate and non-coordinate information to the data collection and processing center.
