Zvenigorod Observatory of INASAN
Zvenigorod observatory is located in 40 km from Moscow (φ = +550 41’ N, λ = 2 h 27 m E, H = 180 m ).
The observatory is one of the oldest optical satellite tracking stations and operates since 1959. Most of the satellite tracking instruments are photographic cameras and now not in use.
Photographic camera VAU for the satellite observations was installed in 1969. VAU has Maksutov’s menisk system optics. 3 axis mounting has 4 band tracking speed 0 – 6, 6 – 60, 60 – 600, 600-6000 arcsec per sec. Now we have replaced front guide-telescope with wide-angle Hamilton’s camera made by A. Sankovitch in OOO “Suntel-M”.

Zvenigorod Observatory Plans
In 2006 in Terskol observatory (φ = +430 16’, λ = 2h 50m E, H = 3100 m) regular observations of small-size objects in GEO have begun. Main researches are conducted on Zeiss-2000 telescope. The arrangement of the observatory and the existing equipment (CCD-receivers with reducers of focus) allow to find out and register objects up to 20-th star magnitude in the geostationary orbit. Many fragments of space debris, not presented in catalogues are found out. E.g. unknown fragment of 18 star mag. was detected on May 20, 2007 and observed next four nights.
