OPTICAL FACILITIES FOR SPACE OBJECT OBSERVATIONS SPACE CONTROL AND ANALYSIS SYSTEM (UKRAINE)V. Lopachenko
The Space Control and Analysis System obtains data both from the optical facilities that belong to the various subdivisions of the National Space Agency of Ukraine, and from the external organizations that have contracts for spacecraft observations.
The Space Control and Analysis System receives data directly from the following instruments: AZT-28, AZT-8 (Evpatoria) and AZT-28 (Dunaevtsy). The AZT-28 telescopes have been recovered and modified in the past 5 years. It’s possible to capture and track space objects using even rough pointing data thanks to the specially developed tracking algorithms. The algorithm of the given segment scanning has been developed for the calculation of the GEO positions. These algorithms are successfully used for tracking the spacecraft in emergencies, for initial spacecraft tracking based on radar measurements, and for the annual surveys of the GEO region. During periods of the vernal equinox survey, observations of the GEO regionhave accomplished: 364 GEO tracks were obtained in 2004 and 187 GEO tracks were obtained in 2005. The set of equipment and software was designed for obtaining the photometric information on the basis of the AZT-28 telescope (Evpatoria). Joint spacecraft observations were carried out with the scientific and technical cooperation of the observatories in Odessa and L’vov. The program for photometry data processing is under development.
Measurements of selected space objects have been carried out by means of AZT-8. Currently the rotation unit has been mechanically recovered. The telescope has been equipped with CCD-cameras, and a data control and read-out system. This instrument is planned to be used for tracking space objects of low brightness and small angular motion velocities.
