Komsomolsk-on-Amur. Space echelon objects SPRN

The Russian Federation is armed with a number of SPRN stations, which are controlled from headquarters in Solnechnogorsk. There are also two control centers - the Western and Eastern SPRN space echelon control posts. The primary one is in the Kaluga Region, not far from the village of Rogovo, and the other reerve station not far from Komsomolsk-on-Amur on the shores of Lake Hummi. The 300-ton antennas installed here in radio-transparent domes continuously monitor the constellation of military satellites in highly elliptical and geostationary orbits. At the CP SPRN, information is being continuously processed from spacecraft and ground stations, followed by its transfer to headquarters in Solnechnogorsk.

Throughout the 1960s The development of a high-orbit space system for detecting launching ballistic missiles in the active part of the flight by emission of torches from rocket engines using passive optical equipment continued. This system, created at the Central Research Institute "Comet" under the leadership of Academician Anatoly Savin, was adopted as the space segment of the SPRN in 1983. The development of domestic SPRN, its means and the manufacture of technological equipment was entrusted to research institutes, design bureaus and factories of the Ministry of Radio Industry, the development of design documentation and construction of facilities - to the Ministry of Defense, installation and adjustment works - to the Head Production and Technical Enterprise of the Ministry of Radio Industry, state testing of tools and systems in general - at the Research Institute of the Ministry of Defense. The Air Defense Forces were identified as the customer of the SPRN.

The last geostationary satellite of the Oko-1 ballistic missile launch detection system (Cosmos-2479) failed in March-April of 2014. Launched in orbit in March 2012, it worked for only two years instead of the planned five to seven years. There were problems with imported batteries and, ultimately, the satellite’s power system stopped working. Two more satellites remained in highly elliptical orbits - Cosmos-2422 and Cosmos-2446. They are placed in orbits in such a way that the interval during which they can observe ballistic missile launches from the United States is not more than 12 hours a day. The devices transmit real-time information to control points: western - Serpukhov-15 (Kurilovo village, Kaluga region) - and eastern, located in the Komsomolsk-on-Amur region.
