Okno (Russian: Окно meaning window) is a Russian space surveillance station located in Nurak in Tajikistan. It is run by the Russian Space Forces and is part of the Centre for Outer Space Monitoring. It is located 2,216 metres (7,270 ft) above sea level in the Sanglok mountains, an area with clear night skies. Another facility, Okno-S, is in the Russian Far East.
The facility consists of a number of telescopes in domes and is similar to the US GEODSS system. It is designed for the detection and analysis of space objects such as satellites. The designers were awarded a Russian state prize for science and technology in 2004.
