Okno
Okno is described as an optical-electronic facility which uses Optical telescope, telescopes to track satellites and spacecraft between and above the Earth. It is located at high altitude, above sea-level near the civilian Sanglok astronomical observatory.Plans
Little is known about Okno-S. The project started at Krasnogorsk, Russia, Krasnogorsk mechanical plant in 1980, under the direction of V S Chernova, and the initial design was completed in 1985. In 1989 Russian military contractor Vympel NPO, Vympel released a draft design of a number of space surveillance complexes including Okno-S. One analyst, Sean O'Connor, says that the original plan was for four Okno installations and four Okno-S installations. This was later reduced to one in Ukraine and one in Eastern Russia. A report by Lenta.ru in 2004 said that one Okno-S was under construction.Location
Sources agree on the rough location of the site in Primorsky Krai in the Russian Far East. It is described as being on Gora Lysaya ( rus, гора Лысая) 'Bald Mountain' near Spassk-Dalny, north of Vladivostok.. A location estimated by Allen Thomson is but there are also two other mountains called Gora Lysaya closer to Vladivostok at and .. Panoramio photos in Google Earth show a Lysaya Gora at 44.380 N, 132.946 E, quite close to Spassk Dalny. Sean O'Connor states that the lack of good satellite photography is stopping open source intelligence researchers identifying the precise location.Facility
There is speculation on the differences between Okno and Okno-S and what the facility actually consists of. Sean O'Connor says that it only covers the region between and above the Earth, providing information on satellites in geostationary orbit. Something in the Federation of American Scientists, FAS sourcebook says that the site has two components. This says that equipment with the GRAU index 60Zh6 covers craft in higher orbits and 59Zh6 and 57Zh6 covers craft in lower orbit.. The whole facility is given the name Object 2327S.Other facilities
Primorsky Krai is mountainous and has other space and astronomical facilities. Krona-N, another military space surveillance facility is near Nakhodka at . Military unit 20096 obtains coordinates and reflecting features of space objects, and transmits this information to a unified system. A civilian solar observatory, Ussuriysk Astrophysical Observatory, is in Ussuriysk.References
