Tselina (satellite)

Last updated

Tselina (Russian : Целина) is a Russian, formerly Soviet Union, military space-based radio surveillance system. It is capable of determining the exact location of radio-emitting objects and also their type, modes of operation, and how active they are. For instance, preparation for a military operation may raise the activity of the radio communications. Detection of these communications by a space-based surveillance system can provide early warning of this activity, warning that may be unavailable by other means.


Initially divided into "overview" (Tselina-O) and "detailed" (Tselina-D), since about 1980 the system has been integrated into a single satellite, Tselina-P, [1] which is also known as Tselina-2. The system's primary subject is enemy radar equipment. Tselina has been numbered as part of the Kosmos series. In total 130 Tselina satellites have been launched. [2]

Plesetsk Cosmodrome Spaceport in Mirny, Arkhangelsk Oblast, northwestern Russia

Plesetsk Cosmodrome is a Russian spaceport located in Mirny, Arkhangelsk Oblast, about 800 km north of Moscow and approximately 200 km south of Arkhangelsk, the cosmodrome dates from 1957. Originally developed as an ICBM site for the R-7 missile, it also served for numerous satellite launches using the R-7 and other rockets. Its high latitude makes it useful only for certain types of launches, especially the Molniya orbits, so for much of the site's history it functioned as a secondary location, with most orbital launches taking place from Baikonur, in the Kazakh SSR. With the end of the Soviet Union, Baikonur became a foreign territory, and Kazakhstan charged $115 million usage fees annually. Consequently, Plesetsk has seen considerably more activity since the 2000s.

Zenit (rocket family) Soviet (now Ukrainian) RP-1/LOX fueled rocket, for satellite launch

Zenit is a family of space launch vehicles designed by the Yuzhnoye Design Bureau in Dnipro, Ukraine, which was then part of the Soviet Union. Zenit was originally built in the 1980s for two purposes: as a liquid rocket booster for the Energia rocket and, equipped with a second stage, as a stand-alone middle-weight launcher with a payload greater than the 7 tonnes of the Soyuz but smaller than the 20 tonnes payload of the Proton. The last rocket family developed in the USSR, the Zenit was intended as an eventual replacement for the dated Soyuz and Proton families, and it would employ propellants which were safer and less toxic than the Proton's nitrogen tetroxide/UDMH mix. Zenit was planned to take over crewed spaceship launches from Soyuz, but these plans were abandoned after the dissolution of the Soviet Union in 1991.

The Tsyklon, GRAU index 11K67, was a Soviet-designed expendable launch system, primarily used to put Cosmos satellites into low Earth orbit. It is based on the R-36 intercontinental ballistic missile designed by Mikhail Yangel and made eight launches, with seven successes and one failure. All of its launches were conducted from LC-90 at the Baikonur Cosmodrome. It is sometimes designated Tsyklon-2A, not to be confused with the later Tsyklon-2 rocket. It was introduced in 1967 and was derived from the R-36 ICBM. It was retired in 1969.

State Space Agency of Ukraine

The State Space Agency of Ukraine is the Ukrainian government agency responsible for space policy and programs. Along with the Ukrainian Defense Industry and the Antonov Aeronautical Scientific-Technical Complex, it is a major state complex of the national defense industry of Ukraine. The agency was formed in 1992 based on the Soviet space program potential based in Ukraine following dissolution of the Soviet Union.

It produces spacecraft, launch vehicles (rockets), liquid-propellant rockets, landing gears, castings, forgings, tractors, tools, and industrial products. The company is headquartered in Dnipro, and reports to the State Space Agency of Ukraine. It works with international aerospace partners in 23 countries.

Zenit (satellite) Series of Soviet spy satellites

Zenit was a series of military photoreconnaissance satellites launched by the Soviet Union between 1961 and 1994. To conceal their nature, all flights were given the public Kosmos designation.

The Zenit-2M, Zenit-2SB, Zenit-2SLB or Zenit-2FG was a Ukrainian expendable carrier rocket derived from the Zenit-3SL. It was a member of the Zenit family of rockets, which were designed by the Yuzhmash.

Signals intelligence operational platforms by nation

Signals intelligence operational platforms are employed by nations to collect signals intelligence, which is intelligence-gathering by interception of signals, whether between people or between machines, or mixtures of the two. As sensitive information is often encrypted, signals intelligence often involves the use of cryptanalysis. However, traffic analysis—the study of who is signalling whom and in what quantity—can often produce valuable information, even when the messages themselves cannot be decrypted.

Gonets Russian civilian low Earth orbit communication satellite system

Gonets is a Russian civilian low Earth orbit communications satellite system. It consists of a number of satellites, derived from Strela military communications satellites. The first two satellites, which were used to test and validate the system, were launched by a Tsyklon-3 launch vehicle from the Plesetsk Cosmodrome on 13 July 1992, and were designated Gonets-D. The first operational satellites, designated Gonets-D1, were launched on 19 February 1996. After launch, the first three satellites were given military Kosmos designations, a practice which was not continued with the other satellites.

The Tsyklon-4, also known as Tsiklon-4 and Cyclone-4, was a Ukrainian carrier rocket which was being developed for commercial satellite launches. Derived from the Tsyklon-3, it had a new third stage, a larger payload fairing, and a modernised flight control system compared to its predecessor. The control system had been developed by JSC Khartron.

Strictly speaking, a satellite collision is when two satellites collide while in orbit around a third, much larger body, such as a planet or moon. This definition can be loosely extended to include collisions between sub-orbital or escape-velocity objects with an object in orbit. Prime examples are the anti-satellite tests by the United States and China.

Kosmos 955 was a Soviet ELINT satellite, launched from the Plesetsk Cosmodrome on September 20, 1977 at 01:01 UTC. The satellite's mass was 2,500 kg. Kosmos 955 had a periapsis of 631 km, apoapsis of 664 km, period inclination of 81.2° and an orbital eccentricity of 0.002346999943256378. It was launched by a Vostok-2M carrier rocket.

Kosmos 1805 was a Soviet electronic intelligence satellite which was launched in 1986. The first of four Tselina-R satellites to fly, it was constructed by Yuzhnoye with its ELINT payload manufactured by TsNII-108 GKRE. Since it ceased operations it has remained in orbit as space junk, and in April 2012 NASA's Fermi Gamma-ray Space Telescope was forced to maneuver to avoid a collision with the derelict satellite.

Kosmos 2221 is a Russian Tselina-D missile ELINT satellite which was launched in 1992.

History of the United States Space Force History of American military development

While the United States Space Force gained its independence on 20 December 2019, the history of the United States Space Force can be traced back to the beginnings of the military space program following the conclusion of the Second World War in 1945. Early military space development was begun within the United States Army Air Forces by General Henry H. Arnold, who identified space as a crucial military arena decades before the first spaceflight. Gaining its independence from the Army on 18 September 1947, the United States Air Force began development of military space and ballistic missile programs, while also competing with the United States Army and United States Navy for the space mission.

Kosmos 1408 was an electronic and signals intelligence (ELINT) satellite operated by the Soviet Union. It was launched into low Earth orbit on 16 September 1982, replacing Kosmos 1378. On 15 November 2021, it was destroyed in a Russian anti-satellite weapons test.
